4CH (8 Wavelengths) CWDM MUX/DEMUX 1471–1611nm with 1310nm Port
Single Fiber CWDM Multiplexer – 1U Rack System with 4 LGX Slots
The 4CH (8 wavelengths) CWDM MUX/DEMUX is a passive optical multiplexing system designed to combine multiple CWDM wavelengths onto a single optical fiber. The device supports CWDM channels from 1471 nm to 1611 nm, enabling efficient wavelength multiplexing for metro, access and enterprise fiber networks.
This solution allows up to 8 CWDM wavelengths to be transmitted over a single fiber, significantly increasing network capacity without requiring additional fiber infrastructure.
The system also includes a 1310 nm port, enabling integration of standard optical services alongside CWDM wavelengths. The device is delivered in a 1U rack chassis with four LGX4 slots, allowing flexible configuration and expansion.
