4xE1/T1+ GbE Fibre Multiplexer

4xE1/T1+ GbE Fibre Multiplexer

The FRM220-GFOM04 is a 4 channel E1/T1 fibre multiplexer with an additional Gigabit Ethernet trunk, plus order wire and clear channel RS-232, constructed as a two slot wide card for the FRM220 series. When the FRM220-GFOM04 card is placed in the FRM220 rack with NMC, the management can view the converter card's status, type, version, fibre link status and alarms. The card can be configured to enable or disable the port, reset the port, and provide local or remote diagnostic loopback. The 1+1 redundant optical aggregate of this multiplexer employs industry standard pluggable optics (SFP) operating at 1.25Mbps data rates. The SFP modules can be chosen to support single-mode, multimode, single fibre bi-directional or Coarse and Dense Wave Division Multiplexing (CWDM and DWDM).
