GHLW Uni-tube Non-metallic Steel Wire Armored underwater/Submarine Fiber Optic Cable
A submarine communications cable is a cable laid on the sea bed between land-based stations to carrytelecommunication signals across stretches of ocean and sea.
The offered cable is qualified for undersea application down to 5000m ocean depth for burial or surface laid.
This Light Weight cable can be spliced using flexible joint closure or Universal Quick Join .
Feature
