Scalable 8 channel DWDM multiplexer

Scalable 8 channel DWDM multiplexer

8-channel DWDM multiplexer for bandwidths of 10 Mbps up to 100 Gbps. The SPEED-DWDM 81E-34/41-A is a purely passive Mux/Demux module providing 8 DWDM and four extension ports in one unit. In point-to-point connection up to eight applications can be transmitted without additional efforts by using one pair of fibres in a first step. Using the scalable design with four extension ports, further channels can be used for services. Each DWDM channel supports bandwidths of 10 Mbps to 100 Gbps protocol transparent. The The SPEED-DWDM 81 series represents an innovative and scalable system for transmission of up to 40 independent applications over one pair of fibre.
