High-density optical fiber management faces two challenges: protection and maintenance.

Nowadays, with the surge in data services, people have higher requirements on the number and capacity of data transmission, and the construction of large data centers is also growing, with 10 Gb transmission gradually being used. It is understood that 10g transmission methods include 10G optical fiber and 10g copper cable. Take twisted pair wires as an example. Currently, Cat6A and seven types of cables support transmission of up to 100 m in 10g. Each port consumes about power and the delay time is about 4 microseconds.

The 10GBase-SR short-wave long optical fiber module is usually used to optimize multi-mode optical fiber through OM3 laser. It can support transmission of up to 300 m 10 m. The power consumption on each port is about 3 W, and the delay time is less than 1 microsecond. Therefore, the optical fiber network has the advantages of low latency, long distance, and low power consumption.

In addition, the ADSL Broadband Based on telephone lines has been gradually replaced by "fiber-optic entry", and the cabling systems of data centers are increasingly using fiber networks, "light-to-copper withdrawal" has become a trend in data center construction. According to the Survey Report, the number of Application of Fiber ports in data centers around the world has exceeded the number of copper ports, and users are facing the situation that the number of fiber ports in the cabinet is increasing and the density is increasing. In the big data era, high-density optical fiber management is facing two major challenges.

1. Physical Protection of optical fiber cables. Excessive bending is the main cause of extra losses when optical signals are transmitted over optical fibers. The loss caused by visible bending of optical fibers becomes macro bending loss, therefore, protecting the bending radius is an important factor to ensure the performance of the optical fiber. Generally, the industry requires that the bending radius of the optical fiber should be at least 20 times the diameter of the cable during installation, and the bending radius should be at least 10 times if it is fixed, most of the time, excessive Optical Fiber Jumpers do not meet the bending radius requirements during winding.

In the aspect of optical fiber cables, especially Optical Fiber jumpers, physical protection is required. Pay special attention to the protection of Optical Fiber transition locations-pigtails and patch cord roots, the high-density optical fiber management system should have dedicated fusion node protection and redundant pigtails.

2. Data Center maintenance. Generally, the lifecycle of a data center cabling system is about 5-10 years. During this period, the cabling system will experience a lot of maintenance work, including adding and changing the cabling system. If the patch cord is neat and beautiful when the cabling system is completed, and then it becomes messy, there is a lack of planning and design for the Cable Routing, there is a lack of cabling channels, and there is no place for the jumper to be unordered, therefore, many problems may occur. For example, the bending radius is not protected, and the Jumper peer location cannot be found, which can only waste a lot of time searching. Idle ports may lead to resource waste.

Third, high-density optical fiber cabling systems should be considerate. A well-designed high-density optical fiber cabling system can minimize system maintenance time and improve reliability, so that the wiring system can provide maximum availability throughout the entire lifecycle.

To this end, we first need to provide an optimized cable cabling channel. The optimal channel design should include protection for the bending radius of the jumper, adequate cable capacity, easy to increase and remove. In addition, the optical fiber plug of the high-density optical fiber cabling system is small and closely arranged. The plugging operation on a certain optical fiber port cannot affect the adjacent Optical Fiber port.
