Optical fiber distribution frames play an important role in the safe operation and flexible use of optical fiber communication networks, which are specifically manifested in the following four aspects:
1. After the optical fiber jumper enters the rack, the optical fiber distribution frame can fix the optical fiber jumper on the rack, and mechanically fix its outer sheath and reinforcing core to protect the optical fiber jumper from external mechanical damage .
2. The optical fiber distribution frame adopts a box structure, which can save space and optimize cable management.
3. The high-density pre-termination system used in the optical fiber distribution frame can enhance the performance of the network and make the network reliable and expandable.
4. The optical fiber distribution frame can easily and quickly deploy high-density interconnection and cross-connection in the data center, simplify wiring deployment, increase wiring density, and effectively reduce wiring failures, making wiring flexible.
Take 6-core indoor multi-mode fiber and 24-port fiber distribution frame as an example:
Assuming that there is a central computer room and 5 floors of wiring closets, it can be determined that there are 5 optical fibers. At this time, the optical fiber distribution frame is 5 (one in the wiring closet on each floor) + 1 (one in the central computer room) = 6
Optical fiber distribution frame in the central computer room = 4 (4 core fibers) * 5 (5 fibers) = 20, 20 <24, so only one is enough, if it is 10 fibers, then 4 * 10 = 40, 40<48, at this time, the central computer room needs 2 light distributions.
There is also a situation that is often encountered in actual operation. There is both a central computer room and a floor wiring closet on the first floor. In this case, if everything is in the same cabinet, the optical fibers can also be combined into the same optical distribution.
