1-Port E1/T1+100M Ethernet Fibre Multiplexer

1-port E1/T1+100M Ethernet Fibre Multiplexer

The FRM220-FOM01 is a modular design for E1/T1 + Fast Ethernet multi-service to single strand fibre PDH multiplexer. FRM220-FOM01 provides E1/T1 transmission transparently, pure 100Mbps Fast Ethernet simultaneously. The fibre optic line gives you the options to choose from most popular fibre cabling connectors such as, ST, SC, FC or SFP-LC. Both multi-mode and single mode models are available as well as BiDi which allows bi-directional transmissions using only a single fibre cable with SNMP and Web-based management in the FRM220, the Network administrator can monitor, configure and control the activity of each card in the chassis.
