100GHz 2-Channel Dual Fiber DWDM OADM with Monitor Port
ITU-T G.694.1 Compliant | LC/UPC | Plug-in LGX Module | West & East Line Ports
The 100GHz 2CH Dual Fiber DWDM OADM (Optical Add-Drop Multiplexer) is a fully passive LGX plug-in module designed for efficient add/drop functionality in C-band DWDM transmission systems. Built in accordance with the ITU-T G.694.1 100GHz (0.8nm) grid, this solution enables the drop and add of two DWDM channels within a dual-fiber architecture while maintaining ultra-low insertion loss and high channel isolation.
This compact and scalable DWDM OADM module is ideal for telecom operators, metro networks, broadcast and TV distribution, data centers (IDC), financial networks, government infrastructure, and cloud backbone environments.
