Description
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. The modems have two fibre ports which enable sets of Fibre Modems to be arranged in branch or loop configurations. Each fibre port utilises a pair of fibres per link to provide full-duplex communication. Up to 5 Fibre Modems can be connected in series. Both Single Mode and Multimode versions of the Fibre Modem are available.
Features
- Single Mode Fibre Modems extend 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
Specifications
- PCB: 96mm(L) x 96mm(W)
- 11-14V DC (from LAN or separate battery backed external power supply) @ 20mA minimum operational current (max 120mA)
