InSky OPGW S part no.
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


Stainless steel tube filled with water-blocking gel


Stranded wires (aluminum-clad steel wires and/or aluminum alloy wires)


Stranded wires (aluminum-clad steel wires and/or aluminum alloy wires)

Up to 432 fibers

ACS wires are highly corrosion-resistant

Optical ground wire (OPGW) shields high-voltage conductors from lightning strikes

Aluminum alloy wires provide conductivity for fault current
