100GHz 4-Channel Dual Fiber DWDM OADM with Monitor Port
Plug-in LGX Module, LC/UPC, West & East – ITU-T G.694.1 Compliant
The 100GHz 4CH Dual Fiber DWDM OADM (Optical Add-Drop Multiplexer) is a fully passive LGX plug-in module designed for high-capacity C-band DWDM networks. Built in accordance with the ITU-T G.694.1 100GHz (0.8nm) grid, this solution enables the drop and add of four DWDM channels in dual-fiber transmission systems while maintaining extremely low insertion loss.
