Stainless steel tube optical fiber unit, HDPE inner sheath, Steel wire armored, Bitumen flooding, PP yarn roving.
Performance
Application
Submarine cable communication system
Operating Temperature
-20°C~+50°C
Features and Benefits
Central stainless steel tube Good mechanical and thermal protection
Special filling gel in loose tubes Reduce or eliminate reflection losses and prevent water penetration
Stainless steel tube is drawn and pulled out after welding Fiber excess lengths are controlled precisely
Note:
The cable is designed to protect the optical fiber from the harsh undersea environment for 25 years
Both repeaterless and repeateredtypes are available as lightweight (LW), lightweight-protected (LWP), single-armored (SA), double armored (DA) and rock armored (RA) cables
Operate up to water depths of 8,000m
