FMUX04E is a fixed design for 4xE1 + Fast Ethernet multi-service to dual strand fiber PDH multiplexer. FMUX04E provides E1 transmissiontransparently and pure 100Mbps Fast Ethernet simultaneously. The fiber optic line is based on SFP technology that allows the flexible useof Multimode or Single mode lines and enables support for different wavelengths and distances. The use of bi-directional SFPs maximizesthe utilization of fiber optic line and results in saving line costs. The multiplexer can be equipped with optional AC and DC power suppliesfor redundant operation. With SNMP and Web-based management in the FMUX04E, the administrator can monitor, configure and controlthe activity remotely.
