 Patch Panel—the Traffic Light for Cabling Alerter l'administrateur Recommander à un ami Lien de l'article 

Patch Panel Overview

The patch panel, also known as the patch bay, patch field or jack field, is a functional unit with a number of same or similar jacks, designed to conveniently and flexibly connect, disconnect and monitor circuits in the cabling network. There is no doubt that the patch panel plays an important role in collecting data and routing it to the intended destination, with the function of enabling the ease of cabling network management and avoiding the data transmission error or failure.

At present, there are both copper and fiber patch panels available on the market, both of which are very popularly used due to their features and advantages. To better know about the patch panel, here offers a kind of 48 port cat6 patch panel in the following figure. From this figure, you can easily learn the appearance of the front and rear of the 48 port cat6 patch panel.

Patch Panel Importance to Cabling Network

We used to regard the patch panel as the "traffic light" for our cabling network. Is there any evidence to support this statement? In fact, we can't deny that no matter how large or small the patch panel is, it is always the crucial element in our cabling network that has the ability to terminate cable elements and transmit the signal to the final destination. Moreover, using the patch panel can better install and manage the multiple cables in our cabling network, for an easier cabling management.

With the mentioned above advantages and constantly improved functions, the patch panel becomes more and more commonly used in computer networking, recording studios, radio, television, etc. Since it is so important to our system, we should ensure that there is no problem with the patch panel before our system runs. Because if there is something wrong with the patch panel, the data would be transmitted wrongly or unsuccessfully.

Selecting a Suitable Patch Panel for Your Cabling Network

As the patch panel is so crucial in the administration of the telecommunications network, it is highly recommended to select a proper patch panel for better cabling management. Since there are both copper and fiber patch panel available on the market, let's discuss the advantages and disadvantages of the two kinds of the patch panels and select one type which is the most suitable for our system.

It is well known that the patch panel can be part of networks with either fiber or copper cabling. As fiber can transmit the signals faster than copper, does it mean that fiber patch panel performs better than copper patch panel in the cabling network? The answer is no. Why? Because all the patch panels are subject to the same standards that provide signal and speed performance ratings for other network components, no matter which materials the patch panels are made up of. Meanwhile, the patch panel is primarily used for directing signal traffic rather than move signal at a required speed. Hence, the materials of the patch panels do make little difference in the cabling performance. As for the manufacturing cost, fiber patch panel is much expensive than copper patch panel that can be up to 40 percent higher. In short, copper patch panel is really a good choice for cabling network if the three factors mentioned above is considered.

Is there any advantage if we choose the fiber patch panel for our cabling network? Of course. The fiber patch panel has only two ports and doesn't require the hardwiring, which is much easier to install than the copper patch panel. After all, each pair of the wires should have a port if you choose the copper patch panel, which may take more time to install.

Conclusion

The patch panel is the "traffic light" in cabling network which allows for terminating long and troublesome cables, enabling the signals to be transmitted directly through a patch code to its destination. Although there are both copper and fiber patch panel available on the market, the copper patch panel is highly recommended as an cost effective solution. Do you consider owning one copper patch panel at hand? You can simply get it from FS.COM that offers 24 port cat5 patch panel, 48 port cat5 patch panel, 24 port cat6 patch panel and 48 port cat6 patch panel.

 Comparison of Cat5e and Cat6 Ethernet Cable Alerter l'administrateur Recommander à un ami Lien de l'article 

Although the copper-based patch cable performs not so well as the fiber patch cable in Ethernet network, it is still popularly used due to its advantages of low cost, high flexibility, easy installation and operation. So far, there are various kinds of copper-based patch cables that were published and came into the market in succession, such as, cat5/cat5e, cat6/cat6a and cat7 Ethernet cable, etc. Among these copper-based patch cables, Cat5e and Cat6 Ethernet cable are two of the most commonly applied types that have similar features and functions, which may be a little hard to distinguish. Do you also feel confused? Let’s study the knowledge of these two patch cables and acquire which one is more suitable and cost effective to be used.

Introduction to Cat5e and Cat6 Ethernet Cable

Cat5e Ethernet cable is an improved version of Cat5 Ethernet cable, published in early 2001. In comparison with Cat5 Ethernet cable, it has a very similar appearance, but composed of four pairs of copper wires rather than the two pairs that cat5 Ethernet cable features. Furthermore, the pairs of copper wires in the Cat5e Ethernet cable are twisted more tightly, reducing or eliminating the crosstalk when working in Ethernet network. After the upgrades, it has become the most common type of Ethernet cabling applied in modern homes and offices, offering much faster transmission rate, wider bandwidth and higher performance. From the following figure, you can see a blue Ethernet cable on the left side which is just an example of the Cat5e Ethernet cable.

Cat5e and Cat6 Ethernet Cable

The one on the right side of the figure is a Cat6 Ethernet cable, which was introduced to the market a year later than the Cat5 Ethernet cable. It is usually made up of four unshielded twisted pairs (UTP) and terminated with RJ45 jacks, capable of supporting the 10Base-T (Ethernet), 100Base-TX (Fast Ethernet), 1000Base-T (Gigabit Ethernet) and 10GBase-T networks. Compared to the Cat5 Ethernet cable, the Cat6 Ethernet cable increases the frequency responses, tightens the crosstalk specifications and introduces more comprehensive crosstalk specifications, for a greatly enhanced performance.

Cat5e vs. Cat6 Ethernet Cable

After knowing the basic information of cat5e and cat6 Ethernet cable, you must recognize that these two Ethernet cables feature different characteristics and perform differently, even if they seem to have common in appearance and function. Then what’s the detailed information about the differences between cat5e and cat6 Ethernet cable?

Different Transmission Speed

There is no doubt that the transmission speed is always the priority if you are considering making the upgrades for your Ethernet network, so does the upgrades from cat5e to cat6 Ethernet cable. As the cat5e Ethernet cable is able to used in 1GBase-T network at most and can only performs up to 100 MHz, the cat6 Ethernet cable is improved to support 10GBase-T network with data rate of up to 250 MHz that is more than twice that of the cat5e Ethernet cable.

Different Transmission Distance

As we all know, cat5e and cat6 Ethernet cable are copper-based patch cables which are only able to transmit signals for very short distances. What’s more, the data rate also affects the transmission distance. In simple words, the higher the data rate is, the shorter the transmission distance will be. Hence, when the signals are only need to be transmitted in a low data rate, both cat5e and cat6 Ethernet cable have the ability to transmit them at lengths up to 100 meters. But if the data rate is required to be the maximum speed, the cat5e and cat6 Ethernet cable can only reach 37 meters and 50 meters, separately. If transmission distance is longer than 100 meters, you are suggested to use the repeaters or switches to amplify the signals.

Different Reliability

The network reliability is also an important factor that you should take into account when deploying your network. Because if there are serious electrical interference in your network, the network reliability may be not so good and negatively influence the performance of your network, thereby the data transmission in your network would be in a wrong way or failed. To ensure a more reliable and stable network, the reliability upgrades is also done from cat5e to cat6 Ethernet cable, with the improvement of deterring signal interference from affecting your network. By using the advanced cat6 Ethernet cable, you’ll be able to have a longer and more reliable period of uptime, regardless of how close your network is to other surrounding networks.

Conclusion

The upgrades always occur with improved features swiftly, like the copper cable upgrades, to face the increasing requirements of the Ethernet network. Since the cat6 Ethernet cable is designed with the improved features of faster transmission speed, longer transmission distance and higher reliability, it is much more commonly used than cat5e Ethernet cable that can be available at a little expensive cost. Hence, you are strongly recommended to use cat6 Ethernet cable to deploy your network with higher performance.

 Straight-Through vs. Crossover Cable Alerter l'administrateur Recommander à un ami Lien de l'article 

It is well known that network patch cable can be commonly wired as straight-through or crossover cable, used for data transmission. Both of these two network patch cables are made up of four pairs of high performance twisted wires with different colors, terminated by the RJ45 keystone jacks at each side of the cables. As for their applications, they are designed for serving different aims, with different wire arrangements inside their cables, which will be introduced in the following text for guiding you to pick the most proper one for deploying you network.

Different Wiring Standards for Wire Arrangements

Before discussing the differences between the straight-through and crossover cable, it is necessary to introduce two wiring standards, T568A and T568B, for better understanding the different wire arrangements in each kind of the cable. These two kinds of wiring standards are recognized by ANSI, TIA and EIA for wiring the network patch cables. Generally, the T568B wiring standard is more widely used than the T568A wiring standard, as the default wiring scheme for twisted pair structured cabling. If you are unsure of which to use, then choose T568B to arrange the wires inside the cable.

T568A and T568B Wiring Standard

In general, there are eight colored wires in a straight-through or crossover cable, which should be arranged according to the corresponding order of the wiring standard T568A or T568B. That’s to say, the wires with different colors should be terminated in the right positions of the RJ45 keystone jack where the wire colors and the colors in the RJ45 keystone jack are the same, as shown in the figure above.

Comparison of Straight-Through and Crossover Cable

When choosing the network patch cable in the store, you’ll easily find the straight-through cable that is commonly used to connect computers to hubs or switches. While the crossover cable with the function of connecting a computer to another computer should be a little hard to find since this kind of network patch cable are not so commonly used as the previous one. But what are the differences between the straight-through and crossover cable? Let’s talk about this topic.

Different Wire Arrangements

As mentioned above, these two kinds of network patch cables have different wire arrangements. For a straight-through cable, there should be only one wiring standard used. It means that both ends of one straight-through cable can be only wired according to T568A wiring standard or T568B wiring standard. Since T568B wiring standard is more popular, here offers the example of a straight-through cable with T568B wiring standard in the following figure. As for the crossover cable, it is designed with two wiring standards in both ends of the cable. In simple words, if there is a RJ54 keystone jack with T568A wiring standard in one end of the crossover cable, there must be a RJ54 keystone jack with T568B wiring standard in the opposite end, as shown in the following figure.

Straight-Through and Crossover Cable
Different Applications

The two kinds of network patch cables are available in the market, used for different applications. As for the straight-through cable, it is applied in local area networks to connect different kinds of devices, for instance, connect a computer to a switch/hub's normal port or a cable/DSL modem's LAN port. It can be an alternative to wireless connections where one or more computers access a router through a wireless signal. As for the crossover cable, it's usually used to connect same type of devices, such as, connect two computers directly, connect two switches/hubs by using normal port in both switches/hubs.

Conclusion

After discussion, we can concluded that the straight-through and crossover cable are designed with different arrangements, serving for different applications. The straight-through cable is usually used for connecting two different kinds of devices, while the crossover cable is highly recommended in the applications where same kind of devices need to be connected. If you want to distinguish the two kinds of cables, you can just check the color orders for the wires inside the RJ45 keystone jacks at both ends of the cables. If the color orders of the wires are the same on both ends, it means the network patch cable is a straight-through cable. If not, it must be a crossover cable or there may be a wiring error in the cable.

 How to Make the Ethernet Patch Cable at an Exact Length? Alerter l'administrateur Recommander à un ami Lien de l'article 

Are the Ethernet patch cables you purchase from the local or online stores always at the proper length? Or not so suitable for your network because they are too long or too short that don’t meet your expectations? Have you ever considered making the improper Ethernet patch cable into a suitable one by yourself, so that you can deploy your network by using you own Ethernet patch cable and save a lot of money, time and space? In fact, terminating the Ethernet patch cables is not so difficult but very useful for fast network deployment, which will be presented in the post. Meanwhile, there are several important things you should take into consideration before making the Ethernet patch cable termination, which will be also illustrated in details. Hope these information will guide you to make your own Ethernet patch cable and then deploy your Ethernet network in a very fast, smooth and cost effective manner.

Selecting a Proper Ethernet Patch Cable

Before making the Ethernet patch cable termination, you should choose one kind of Ethernet patch cable which is most suitable for your network, since there are various kinds of Ethernet patch cables available on the market, such as, cat5, cat5e, cat6, cat6a, cat7, etc. Considering that cat5e, cat6 and cat7 patch cable are the most commonly used ones at present, both of which will be introduced the following text.

cat5e, cat6 and cat7 patch cable

As an upgrade version of cat5 patch cable, cat5e patch cable has the ability to support gigabit speed, allowing for a faster, more reliable and steady network. It is much commonly used in home and office applications. As for cat6 patch cable, it is an enhanced version of cat5e patch cable that has much more sophisticated structure, as shown in the above figure. It is an ideal solution to face future-proof network that supports the transmission speed up to 10 gigabit with a long transmission distance. In contrast to cat5e and cat6 patch cable, cat7 patch cable is a kind of shielded Ethernet cable that has a great improvement in the capacity and reliability. It is more expensive since it has been the most durable and longer-lifespan Ethernet patch cable at present. As for the structural differences among cat5e, cat6 and cat7 patch cable, it is very easy to learn from the above figure.

Choosing a Proper Wiring Scheme

In general, there are two common wiring schemes, T568A and T568B, which are designed to specify the arrangement of the colored wires for terminating the Ethernet patch cable. That’s to say, if you want to terminate your cable, you should arrange the colored wires in a correct order according to the standard of T568A or T568B, as shown in the following figure. As for their applications, T568A is always applied in home-networking connections, while T568B is strongly suggested for the preexisting residential network wiring or other similar projects.

Terminating the Ethernet Patch Cable You Need

There are ten detailed steps to make the Ethernet patch cable you need at an exact length, which will be presented below. Terminating the cable you need according to the following step-by- step procedures can ensure the performance of the DIY cable and the stability of your network.

  • Prepare the essential tools and materials for the cable termination, including some RJ45 connectors, a pair of wire scissors or wire strippers, a spool of Ethernet cable, a RJ45 crimping tool and a network cable tester.
  • Use the wire scissors or wire strippers to cut the Ethernet patch cable you need into a desirable one with the exact length. Besides, you’d better to add two or three inches extra no matter how long you want the Ethernet patch cable to be, for the sake of messing up.
  • Utilize the RJ45 crimping tool to shove the sheath of the cable (about 1 inch) from the end of the cable into the stripper, and lightly squeeze the crimping tool.
  • When the razors slice of the crimping tool pass through the cable jacket, you should twist the cable and pop off the cut end of jacket.
  • Once the jacket is stripped, you can see four twisted pairs of wires with four different colors. You should separate these four pairs of wires into eight individual wires and rearrange them into sequence according to the color order in T568A or T568B.
  • Cut the tips of the wires in order to match with the RJ45 connector. Then guide the wires into the plug and slip them into their own channels. The ends of the wires should reach as far as possible toward the front edge of the plug.
  • Double check and confirm whether the wires are in sequence according to the right order or not, avoiding error connection.
  • Insert the plug into the crimping slot of the crimping tool and squeeze the crimping tool to make the pins inside the plug into the wires and fasten the plug onto the cable. Hence, the RJ45 connector can be a permanent part of the new cable.
  • As for the other end of the cable, just terminate it in the same way, so that you can finish the whole termination process for your own Ethernet patch cable.
  • Test the cable by a network cable tester to confirm that it really works. In addition, if it doesn’t work, you are highly suggested to check the color order of the wires first.
Conclusion

Before making your own Ethernet patch cable, you should choose a proper Ethernet patch cable and a wiring scheme according to your network requires. As for the process of making the cable with an exact length, it is not so difficult as you consider, but easy and fast. The only thing that deserves a bit of attention is to be careful in the whole termination process, so that the Ethernet patch cable can be made at a proper length and work with your network like a charm.

 An In-Depth Look at Mode Conditioning Patch Cable Alerter l'administrateur Recommander à un ami Lien de l'article 

As we all know, fiber optic cable jumper plays an important role in Ethernet network connection, which becomes more and more diversified to satisfy the different connection requirements in recent years. For instance, standard fiber patch cable like single mode patch cable and multimode patch cable, special fiber patch cable like mode conditioning patch cable and bend insensitive patch cable, etc. Among these various fiber patch cables, mode conditioning patch cable has been one of the most popularly used fiber patch cable due to its unique features and advantages, which will be introduced in the following text.

What Is Mode Conditioning Fiber Patch Cable?

Mode conditioning patch cable is a special kind of duplex fiber patch cable that consists of two fibers, a conditioned fiber and a non-conditioned fiber, capped at either end with connectors. In the conditioned fiber, a single mode fiber and a multimode fiber are fusion spliced in an offset manner, with a precise core alignment and angle, protected by a black over-wrap. While in the non-conditioned fiber, there is only a length of multimode fiber. To get a better understand of its structure, you can take the following figure as reference.

mode conditioning patch cable

As shown in the figure above, there are two multimode fibers in one end, and a multimode and single mode fiber in the opposite end. The end with two multimode fibers is designed to connect the cable plant, while the other end connects to the transceiver equipment with the single-mode leg linking to the transmit side. Hence, light signal can be launched on to the multimode fiber in the conditioned one at a specific angle, giving the patch cable its mode conditioning property. Besides, it is worth mentioning that this kind of fiber optic cable is fully compliant with IEEE 802.3z application standards.

Why Mode Conditioning Cable Is Used?

As far as our information goes, 1310nm long wave signal is always transmitted through single mode patch cable for 1000BASE-LX transmission as a cost effective solution. However, if the mentioned above transmission utilizes multimode patch cable, it will cause a phenomenon known as DMD (differential mode delay). In simple words, if the same signal is carried to a multimode patch cable, there will be multiple signals created in the multimode patch cable that may make transmission errors to some extent.

In order to solve this problem, mode conditioning patch cable is put forward that utilizes an offset between the single-mode fiber and multimode fiber to eliminate transmission errors, allowing for 1000BASE-LX signal transmission through multimode patch cable. For example, when 1000BASE-LX routers and switches are installed into existing multimode cable plants, mode conditioning patch cable is highly recommended to adapt the single-mode output of 1000BASE-LX transceivers to a multimode cable network.

Notices for Using Mode Conditioning Patch Cable

After knowing the feature and advantage of mode conditioning patch cable, do you also consider using mode conditioning patch cable to finish the conversion from single mode to multimode? Here are some notices for you so as to use the mode conditioning patch cable in a proper way.

    • Mode conditioning patch cable should be used in pairs to finish the conversion. That's to say, most orders for this kind of fiber optic cable are always in even numbers. If there is an odd number order, the single one must be used for standby application or replacement.

    • Mode conditioning patch cable is only able to convert single-mode transmission to multimode transmission. If the conversion from multimode to single-mode is required, you are suggested to choose a media converter as an easy and cost effective solution.

    • Please check and confirm the connector of your switch before application. If it is equipped with SC or LC connectors, you should connect the yellow leg (single-mode) of the cable to the transmit side and the orange leg (multimode) to the receive side of the equipment. It is imperative that this configuration should be maintained on both ends.

Conclusion

Mode conditioning patch cable enables the conversion from single-mode to multimode with the feature of fusion splicing between single mode fiber and multimode fiber. After knowing its feature and advantage, if you want to choose this kind of cable to finish the conversion in your network, you can order it from FS.COM. It is no doubt that there are various mode conditioning patch cables with different connectors available. Besides, if you cannot find one to meet you requirement, you can also order custom fiber patch cables for your network.
