The structure type of optical fiber ribbon communication cable:

Optical fiber ribbon communication cable can be divided into layered type (GYDTA), skeleton type (GYDGA) and central tube type (GYDXTW) from the structural characteristics.

The structural characteristics of the layer-stranded optical fiber ribbon communication cable are basically the same as those of the ordinary GYTA communication optical cable. The optical fiber ribbons in the cable mainly include 12 cores, 6 cores, and 4 cores, which are the most widely used optical fiber ribbon communication cables at present.

The structural characteristics of the skeleton optical fiber ribbon communication cable, the optical fiber ribbon in the cable is generally 4 cores or 6 cores, which is a dry water blocking structure (no grease in the cable). The fiber core of the floor is connected. The structural characteristics of this communication optical cable determine that it has strong rigidity and is difficult to bend during construction; but in view of its dry structure, it has become a variety recommended by CMCC; in fact, layered stranded communication cables can also be made into Dry or semi-dry water blocking structure features.

Structural features of central tube type communication optical cable Generally speaking, the optical fiber ribbon in the cable is 12 cores and 24 cores. The central tube type communication optical cable has the characteristics of light weight, small diameter and low cost. If the number of cores of the communication optical cable is not large, it should be a better choice in engineering construction. In view of the difficult control of the excess fiber length of the central tube type communication cable, it may lead to the failure of the optical fiber in the cable under extreme ambient temperature. Therefore, whether it is optical fiber ribbon or discrete optical fiber structural features, CMCC does not like to use it; in fact, the center The environmental temperature adaptation performance of the tubular communication optical cable is not so bad, and it can fully meet the application requirements of most scenarios.
