FMUX04A is a fixed design, PDH multiplexer, with 4x E1/T1 plus 4x 10/100/1000Base-T Ethernet switch that provides simultaneousmulti-service through dual (1+1) fiber. The fiber optic line is based on 1.25Gbps SFP technology that allows the flexible use ofMultimode or Single mode optics and enables support for different wavelengths and distances. The use of bi-directional SFPsmaximizes the utilization of fiber optic line and results in saving fiber line costs. The multiplexer can be equipped with optional AC andDC power supplies for redundant operation. With SNMP and Web-based management in the FMUX04A, the administrator canmonitor, configure and control both the local and remote device.
