Dual Fiber 1-Channel CWDM OADM (East & West), LC/UPC, Plug-in LGX4 Module and 4-Slot 1U Rack
The 1-Channel CWDM Optical Add/Drop Multiplexer (OADM) is a passive wavelength management device designed by GLOBALfiber for CWDM networks operating from 1270 nm to 1610 nm.
This dual-fiber OADM supports bidirectional traffic with one CWDM channel assigned to the West direction and one CWDM channel assigned to the East direction. The selected wavelength can be added and dropped independently on either side, enabling flexible point-to-point and ring network deployments.
The module is available in a plug-in LGX4 form factor and can be installed in a 4-slot 1U rack chassis for high-density CWDM applications.
