4x E1/T1 + FE Fiber Multiplexer

4x E1/T1 + FE Fiber Multiplexer Card: FRM220-FOM04/01

The FRM220-FOM04 is a dual slot, 4-channel E1/T1 plus 100M Fast Ethernet to 1+1 redundant fiber multiplexer card with an additional clear channel RS-232 and order wire. When the FRM220-FOM04 cards are placed in the FRM220 rack with NMC, the administrator can view the converter card's status, type, version, fiber link status and alarms. Remote, fiber connected standalone card, can also be managed through in-band management via the chassis NMC. The card can be configured to enable or disable the port, reset the port, and provide local or remote diagnostic loopback. The optical aggregate of this multiplexer employs either a fixed transceiver or industry standard pluggable optics (SFP) operating at OC3/STM-1 data rates (155M). The SFP modules can be chosen to support single-mode, multi-mode, single fiber bi-directional or Coarse and Dense Wave Division Multiplexing (CWDM and DWDM)
