When G.657 fiber is used, the static minimum bending radius is 5h.
Fiber types: single mode G.652 A / B / C / D, G.657 or G.655 A / B / C fiber, multimode A1A or A1B fiber,
Or other types and types of optical fiber;
Number of optical fiber cores: the optical fiber belt is composed of 2-core, 4-core, 6-core, 8-core or 12 core optical fibers, which shall be specified by the user;
Sheath materials: environmental friendly flame retardant PVC, environmental friendly low smoke and halogen-free flame retardant polyolefin (LSZH), environmental friendly polyurethane (TPU)
Or other agreed materials; the loose tube material is usually polybutylene terephthalate (PBT), or
Sheath color: (including the color of optical fiber in the cable) according to the color specified in the standard, but also other agreed colors;
Cable size: nominal cable size, but also other agreed size;
Length: 1km or 2km, 3km can also be other agreed length;
A. Pay attention to the feed depth when stripping the optical cable. The key to peeling the outer sheath of optical cable is to grasp the cutting depth of sheath cutter, otherwise it is easy to break the fiber. In the actual operation, the sheath cutter should be rotated while observing the incision. If the white polyester tape can be seen, the feed should be stopped and the cutter should be removed. This step is a skilled process, which requires many exercises to master the depth of the feed.
B. Fixation of optical cable and stripping of core bundle pipe. After the cable is stripped, fix the cable in the cable connector box, strip the core bundle pipe, and make all preparations before the fiber fusion.
