suspension into an "8" shaped PE jacket. There is no need to erect hanging wires and hooks during the laying process, and the
operation efficiency is high and the laying cost is low. The GYXTC8Y figure 8 fiber cable is very easily laid overhead between
poles and poles, between poles and buildings, between buildings and buildings.

Marking
The characters printed on the optical cable shall be marked at intervals of 1m, and the length shall be numbered in sequence. The starting number of any coil ordering length should start with zero meters. The accuracy of length measurement should be controlled within 1%. Spray printing on optical cable shall include the followingcontents.
- name of manufacturer
- optical cable model
- manufacturing year and month
- Length per meter marked along the optical cable
