Inner Range - Concept: Fibre Modem

Control

Terminals

The Inner Range Fibre Modem provides two separate, optically isolated ports to the Concept system LAN. A set of Fibre Modems are ideal for applications where modules in a Concept system are in different buildings and/or are separated by large distances.

In terms of a Concept system, Fibre Modem links boast maximum LAN distance whilst providing immunity to earth loops, induced electrical noise and propagation of pulses from lightning strikes by virtue of the optical isolation.

Both Single Mode and Multimode versions are available.

Features:

Multimode Fibre Modems extends Concept LAN up to 11Km
Single Mode Fibre Modems extends Concept LAN up to 13Km
Electrical isolation from the remote LAN
Fibre links immune to earth loops and induced noise
Immune to propagation of electrical pulses due to lightning
Supports loop and branch ("Y") configurations
Redundant LAN path when Fibre Modems used in 'loop' configuration
'Loop Fault' and 'Branch Fault' auxiliary outputs
