OPGW Optical Ground Wire 48core Outdoor Aerial fiber optic cable
1. Description
OPGW is a dual functioning cable performing the duties of a ground
wire and also providing a patch for the transmission of voice,
video or data signals . The fibers are protected from environmental
conditions (lightning, short circuit, loading) to ensure
reliability and longevity. The cable is designed to be installed on
transmission and distribution lines to carry voice, data and video
communications, especially in lighting waveform monitoring system,
an observation system for overhead test line, maintenance data
information system, power line protection system, power line
operation system, and unmanned substation monitoring

4. Packing and Shipping
Cable is supplied in lengths as specified in PI or as requirement.
Each length will be shipped on a separate iron-wooden drum. The
minimum barrel diameter of the drum will not be less than 30 times
the cable diameter.
The cable ends will be sealed with plastic protection caps to
prevent water penetration. The ends will be easily accessible for
testing. A final inspection test report with attenuation
performance data for each fiber is attached inside the drum.
