QFAI 2 UNI

QFAI 2 UNI

Variant:

A robust fibre cable suited for harsh ship- and offshore environment. It has no metal content, which leaves it immune to electric and electromagnetic shockwaves.
For LAN and WAN installations as well as telecommunication and data transmission on board. Inner jacket SHF1, outer jacket UV resistant and rodent protected SHF1. Fire resistant; operational for 90 min. if exposed to fire.
