High-density fiber management faces two major challenges to protect and preserve

Has gradually been "fiber to the home" replaced by ADSL-based broadband telephone lines, data center cabling systems are also increasingly using fiber-optic network, "Light of Copper" has become a trend in the data center construction. According to the survey report, worldwide data center, the number of applications over fiber optic ports copper ports, the user is faced with a growing number of fiber ports in the cabinet and more, increasing density of the status quo. Big Data era of high-density fiber management is facing two major challenges.
With the explosion of data traffic, the number of people on the data transmission and capacity have higher requirements, the construction of large-scale data centers more and more, 10G transmission is also gradually being used. It is understood that: implementation of 10G transmission including 10G and 10G copper fiber types. Twisted pair, for example, the current mainstream Cat6A and Cat 7 cables to support Gigabit transmission as far as 100 meters. Per port power consumption of about 10W, delay time is about 4 microseconds.
The 10GBase-SR short-wavelength fiber-optic module commonly employed by OM3 laser optimized multimode fiber as far as 300 meters can support Gigabit transmission, device power consumption per port about 3W, the delay time of less than 1 microsecond. So comparison, the fiber optic network has low latency, long-distance, low power consumption advantages.
First, the physical protection of optical fiber and cable. Excessive bending loss is the main reason for the extra light signals in optical fibers, optical fiber bending loss visible due to become great curved loss, thus protecting the bend radius is an important factor to ensure fiber performance. General industry requirements for fiber bend radius during installation is at least 20 times the diameter of the cable, if you want to maintain a fixed state at least 10 times, most of the time when the excess coiled fiber jumper bend radius not meet the requirements.
Particularly with regard to the fiber optic cable fiber optic patch cord is fragile, you need to pay attention to physical protection, with particular attention to the transition part of the fiber - pigtail splice and jumper root protection, high-density fiber management system should have special protection and redundant node splice I pigtail storage function.
Second, to maintain the data center. Lifecycle normal data center cabling system is about 5--10 years, in this time period cabling system will experience a lot of maintenance work, including additions and changes. If the wiring system when completed jumpers clean and beautiful, but after becoming messy, it is the lack of planning for cable routing and design, lack of alignment channel, jumpers nowhere to go only disorderly accumulation, thus causing a lot of problems , such as bend radius are not protected, you can not find the jumper on the end position can waste a lot of time to find, resulting in waste of resources unused port.
Third, high-density fiber optic cabling system to be considerate. A well-designed, high-density fiber optic cabling system to maximize the reduction of system maintenance time and improve reliability, so that the wiring system to provide maximum available capacity throughout the life cycle.
To do this, we first want to provide optimized design of the cable routing channels, channel optimization design should include jumper bend radius protection, cable has enough capacity to be easy to add and remove. In addition the size of the high-density fiber optic connector fiber management system compact and tightly packed on one fiber port swap operation can not affect the adjacent fiber port.
