InSky OPGW S Optical Ground Wire Stranded (S)

Combines excellent mechanical and electrical properties with much higher zero fiber strain margin to enhance long-term optical reliability. It is also more flexible and crush-resistant than other design types which makes pulling it in faster and makes it possible to pull farther and through more angles.


Central strength member (aluminum-clad steel wire or aluminum alloy wire)


Optical fiber
