Loose Tube Optical Ground Wire(OPGW)
opgw earth wire is surrounded by single or double layers of aluminum clad steel wires(ACS) or mix ACS wires and aluminum alloy wires. are the most widely used cables ,their design is fully adapted to the most common electric line needs.
Specificaitions:
Application:Aerial/ground(earth) wire.
opgw earth wire Standards:
| ITU-TG.652 | Characteristics of a single mode optical fiber |
| ITU-TG.655 | Characteristics of a non-zero dispersion -shifted single mode fibers optical |
| EIA/TIA598 B | Col code of fiber optic cables |
| IEC 60794-4-10 | Aerial optical cables along electrical power lines-family specification for OPGW |
