Arctic Grade QFCI OM3 G8 50/125

QFCI Arctic Grade (QFCU)

Variant:

Fiberoptical cable for the oil- and offshore industry and other harsh environments. The cable has excellent communication properties and is tested to be operative in at least 180 min. at 1000°C which means that it can maintain vital communication in case of a fire situation. Operational in extreme low temperatures. The fibers are protected in jelly filled loose tubes stranded around a central strength member to ensure optimum performance and long life. Each fiber and loose tube is color coded for easy identification during splicing and termination. Outer jacket Arctic Grade SHF2 for extreme environments.
