Suggestions for High-Density Cable Management

People who work in data centers are familiar with cable management. Terrible cable management destroys the stability and availability of networking, especially for high-density applications. Since the advancement of technology brings us to a higher broadband network, high-density components are widely applied to data infrastructures. The importance of high-density cable management should be valued.

Useful High-Density Cable Management Components

Using the right devices for high-density connections will ease the difficulty of cable management. High-density patch panels, high-density TAB patch cables and high-density trunk cables are recommended for high-density installations.

High-Density Patch Panels

High-density patch panel provides fast, intuitive and easy deployment of high-density interconnects and cross-connects in data centers. They also conserve valuable rack space. Compared to standard patch panels, angled styles can facilitate cable management practices. Omitting the necessity of buying new components, reconfigurable panels with various mounting and attachment features can ensure that patch panels are fit for your data center configuration. For instance, the following picture shows an ultra high-density angled patch panel with 144 ports highly welcomed by the high-density network application.

High-Density Patch Cables

High-density cabling has been increased because of the deployment of higher network speeds. Installing cables with smaller overall diameter into dense patch cord trays can save lots of space to improve cable management. The high-density optical fiber also provides better airflow to maintain consistent operating temperatures, reducing the likelihood of failure or downtime. Finger access to each patch cable becomes more difficult as cable density increases. To ensure easy access, looking for high-density patch cords that are easy to remove is important. Thus, the patch cable using a flexible pull-tab efficiently solves the issue. These tabs can help increase cabling density and maintain reliability, preventing you from accidentally loosening surrounding connectors as you access the patch cable you need. The picture below is a typical HD TAB fiber patch cable.


High-Density Trunks

High-density trunks allow tighter trunk cable bends for slack storage and routing. Less space is consumed and installation is easier when using high-density trunks that offer smaller transitions. Cable pulling and cable management are improved when a cable with a smaller overall diameter is used. High-density trunks should also be marked for fast fiber type identification.


Things to Avoid During Installation & Daily Practices

  1. Avoid over-bundling the cables or placing multiple bundles on top of each other, which can degrade the performance of the cables underneath. Additionally, keep fiber and copper runs separated. The weight of the copper cables can crush fiber cables that are placed underneath.
  2. Avoid routing cables through pipes and holes. This may limit additional future cable runs.
  3. Avoid mounting cabling components in locations that block access to other equipment inside and outside the racks. For example, blocking the cooling fans will restrict airflow.
  4. Avoid leaving loose cables on the floor; this is a major safety hazard. Use the horizontal, vertical, or overhead cable managers.
  5. Avoid exposing cables to direct sunlight and areas of condensation.
  6. Avoid mixing different cable types within a bundled group.


In conclusion, a good cable management of high-density devices is very essential to extend their service life. Choose the right components will also facilitate the efficiency of cable management. There is no perfect solution for all your cable management demands. Some suggestions may help you to a certain degree, but you should still arrange your equipment according to the actual environment.

Applications of Special-Purpose Fiber Patch Cables

Fiber patch cable is an indispensable part for fiber optic communication. Signals are depending on this device to finish data transmission. Standard fiber patch cables are the most common patch cables in the market. However, there are some specific applications that need special treatment. Therefore, a range of special-purpose fiber patch cables have emerged as required. This article will recommend several unique but useful fiber patch cables. Maybe one of them will suit your needs.

HD TAB Fiber Patch Cable

As the name suggests, HD TAB fiber patch cable has a special push-pull tab which provides great convenience for high-density installations. Technicians can have easier finger access to installing or releasing the cables without using any additional tools. In today’s market, HD TAB fiber patch cables are usually terminated with LC or MTP/MPO connectors. If you are seeking for a high-density and space-saving solution, HD TAB fiber patch cable is highly recommended.


The uniboot LC fiber patch cable bundles two fibers in a single patch cord which saves much space for cabling. The changing of its LC uniboot connector polarity is easy ,which skips the using of tools. Uniboot LC fiber patch cable is available in different fiber types of single-mode, OM3 and OM4. The purpose of this cable is to deliver maximum connectivity performance in a minimal footprint. If you want to achieve an easier cable management, this is definitely a good choice.

In addition, there is an upgraded version of uniboot LC fiber patch cable – HD uniboot LC fiber patch cable. You can’t miss this one if you are looking for the extreme space saving solution. It is basically the combination of uniboot LC fiber patch cable and HD TAB fiber patch cable. Likewise, two optical fibers are wrapped together in a single strand. The difference is that its connector is attached with a push-pull tab which is more flexible for releasing the connector. It can be applied to data centers and high-density environments.


Keyed LC Fiber Patch Cable

In terms of data security, keyed LC fiber patch cable or secured LC fiber patch cable is the perfect solution. It is designed to prevent unauthorized and inadvertent changes in highly sensitive applications. Keyed LC fiber patch cable is identified by the connector color. Each color of a set of keyed LC connectivity products represents a unique keying pattern that only allows matched color mating. Multiple keyed LC connectivity products are included in this family. The picture below gives an example of the simplex keyed LC connectivity.


Originally, when bending an optical fiber by stress, there will be a bend loss. This sensitive nature of optical fiber causes low efficiency in optical transmission. But it is hard to deal with the problem as bend loss issue is difficult to locate. Fortunately, bend insensitive fiber patch cable is designed to solve this problem. In this kind of cable, a layer of glass is added around the core of the fiber which has a lower index of refraction that literally “reflects” the weakly guided modes back into the core. Many data centers and FTTH systems are deploying this cable to reach lower signal loss.


From this article, we can see that there still exists many other types of fiber patch cables. And special fiber optic cable solutions are always more effective to special applications. By the way, if you just want a standard optical cable, you may consider from the aspects of fiber type, connector type, connector polishing type, fiber count, cable jacket, etc. These options are fit for average circumstances when choosing the optical cables. Hope you choose the right one according to your requirements!
