FMU-MD08A/B
8 Channels Single Fiber DWDM Mux Demux, 1U Half Plug-in Module, LC/UPC
Overview
These compact DWDM Mux Demux work in a pair to provide 8 bidirectional channels
on a single strand of fiber. They use the 8 DWDM ITU grids being used in each direction.
Our DWDM Mux Demux are modular, scalable and are perfectly suited to transport
PDH, SDH / SONET, ETHERNET services over WWDM, CWDM and DWDM in optical metro
edge and access networks.
Highlights
• 8 bi-directional channels using standard 16-channels DWDM ITU grid C43–C58
• Low insertion loss
• Low-profile 1U half 19'' rack plug-in module design
• LC/UPC duplex connectors
• Compliant to ITU G.694.1, 100GHz ITU gird, 0.8 nm spacing
• High quality thin film filter technology
• Passive, no electricity needed (MTBF ca. 500 years)
