4CH (8 Wavelengths) DWDM MUX/DEMUX C31–C38
Single Fiber Passive DWDM Multiplexer – LGX4 Module
The 4CH (8 wavelengths) DWDM MUX/DEMUX is a passive optical multiplexing device designed for efficient wavelength division multiplexing in fiber optic networks. The unit operates on DWDM channels C31 to C38 within the C-band, enabling multiple optical signals to be transmitted simultaneously over a single fiber.
Using 100 GHz ITU-T channel spacing, the device combines and separates up to 8 DWDM wavelengths, allowing network operators to significantly increase fiber capacity without deploying additional fiber infrastructure. The device is delivered as an LGX4 plug-in module, making it suitable for installation in 1U rack enclosures, telecom cabinets and optical transport platforms.
