Commonly used outdoor optical cables can be divided into:
Layer-stranded optical cable and central bundle tube type
Center bundled tube optical cable GYXTW 2~24 cores
The center of the central tube type optical cable is a
loose tube, and the reinforcing member is located around the loose tube. Such as the common GYXTW type optical cable, the number of optical cable cores is small, usually less than 12 cores.
Suitable for short-distance communications and inter-office communications, and more suitable for hot and humid areas
