LanMarin® Fire Cat 7 - SHF1

Variant:

High performance offshore LAN cable with solid conductors, AWG 23/1. Also designed as fire resistant communication cable
for car and railway tunnels. Compliant with the category 7 standards, requiring bandwidths up to 600 MHz. Foil screened pairs
with an overall tinned copper braid. Tested for high-frequency and transmission measurements for class F-link. 
Female Modular plug can be connected to this cable. IEEE 802.3at-2009 Type 4 (PoE++). This cable can be used in rough environments.
