Introduction
As people’s requirements for transmission speed become increasingly high, the number of equipment and cables in data centers is also gradually increasing, and disorderly cables may cause network failures. Therefore, cable management has become one of the essential tasks in data centers. When it comes to cable management, people usually think of cable managements.
A cable management, also known as a cable management, consists of two parts: a cable board and a cover plate. It is a accessory device installed in a cabinet and used in conjunction with a distribution frame. It can make the patch cords connected between the switch and the distribution panel neat; It will not cause the module or switch port to be under stress for a long time due to the weight of the patch cord itself sagging, resulting in network instability or port damage; Added the bending radius of copper patch cords or optical fibers to protect them from bending damage; It is also convenient for later operation, maintenance, and management.
Distinguished by installation direction
It is divided into horizontal cable managements and vertical cable managements, with slightly different functions depending on the placement direction. Horizontal cable management device is used to hide the excess part of the cable at the back of the cabinet; Vertical cable management is the process of placing excess cables in a vertical cable management.
If there are too many patch cords in the cabinet, you can use a combination of horizontal and vertical cable managements.
Distinguished by design type
Divided into keyboard type and D-ring type
The keyboard type focuses on clamping the cables into the neutral position separately; the D-ring type focuses on streamlining the cables, and it is less commonly used in the market because it does not have a cover plate, and if the cables are not streamlined, it will appear unattractive.
Distinguished by the number of ports opened
It is divided into 12 ports and 24 ports. The gap between 12 ports is relatively large, and two cables can be inserted into one port. The gap between 24 ports is relatively small, and generally only one cable can be inserted.
Distinguished by selected materials
It is divided into plastic cable managements and metal cable managements.
Due to being made of plastic, plastic cable handlers have poor durability. After a period of use, excessive cables may cause deformation or discoloration of the plastic cable handlers due to light exposure. However, the wiring cost is relatively low and their applications are also widespread. The metal cable management is relatively sturdy and will not experience the above situations during use, making it safer and more durable.
Distinguished by U number
It can be divided into 1U and 2U. Due to the fact that most rack mounted network devices are 19 inches wide, the width of the cable management rack is standard 19 inches, but there are various sizes of its height. We use “U” to represent the height of the cable management rack, with 1U=44.45mm.
The more common ones on the market now are 1U cable managements and 2U cable managements. When choosing the size of the cable management, we need to ensure that the cable management not only meets the existing cable management needs, but also reserves some space for future cable additions. Generally, a 48 ports patch panel or a 24 ports patch panel can have a 2U cable management placed in the middle.
