4 Channel E1/T1 Plus 100M Ethernet Multiplexer

4 Channel E1/T1 Plus 100M Ethernet Multiplexer

The FMUX04E is a modular design for 4xE1 + Fast Ethernet multi-service to dual strand fibre PDH multiplexer. FMUX04E provides E1 transmission transparently, pure 100Mbps Fast Ethernet simultaneously. The fibre optic line is based on the SFP technology that allows a flexible use of Multimode or Single mode lines and enable the support of different wavelengths and distances. The use of bi-directional SFPs maximizes the utilization of the fibre optic line and results in saving line costs. The multiplexer is equipped by default with redundant AC and DC power supplies for redundant operation. With SNMP and Web-based management in the FMUX04E, the Network administrator can monitor, configure and control the activity remotely.
