Stranded Loose-Tube Non-Armored Optical Cable

Product Overview

Stranded loose-tube non-armored optical cable (e.g. GYTA) uses hydrolysis-resistant high-strength loose tubes filled with special jelly to protect the fibers. A specially designed compact cable core effectively prevents tube shrinkage. The PE jacket offers good UV resistance, with overall excellent mechanical and temperature performance for duct and aerial non-armored applications. Stable and reliable for telecom network build-out and O&M.
