The reserved length should be reasonably set according to the actual situation and relevant standards, such as reserving 1020 meters in the incoming line room when the optical cable enters and exits the office, and reserving 610 meters at the joint and lead-up of the pipeline.

When designing a Fiber Optic Structured Cabling System, planning the length and layout of the fiber-optic cable first requires clarifying the type of communication, bandwidth requirements, data transmission rate, etc. that the Fiber Optic Structured Cabling System needs to support. This helps. In order to ensure the safety of the optical cable, the reserved optical cable should be left in the man (hand) hole of the communication pipeline as much as possible. The minimum size for the “figure-eight”. The Professional Association Of Fiber Optics www. The charter of the FOA was to promote professionalism. 2m, 3m, 10m, or Custom? Complete Guide to Fiber Patch Cord Lengths Fiber patch cords are a must-have in today's high-speed, flexible network setups, as they create "jumpers" between network equipment. Since there can be issues with even shorter fiber cables we recommend only using fibers with that minimum length. If you need a smaller cable length please.
