FOM04 is a standalone 4xE1/T1 + Fast Ethernet Fiber Multiplexer with 1+1 fiber redundancy. FOM04 provides E1/T1 transmissions

transparently along with wire-speed 100Mbps Fast Ethernet simultaneously. The fiber optics utilize industry standard SFP technology that

allows a flexible use of Multimode or Single mode lines and enables the support of different wavelengths and distances. The use of

bi-directional SFPs maximizes the utilization of the fiber optic line and results in saving line costs. With SNMP and Web-based management in

the FMUX20, the Network administrator can monitor, configure and control the activity of each card in the chassis.
