GLOBALfiber 8-Channel Dual Fiber CWDM MUX/DEMUX
(1470–1610nm with 1310nm and Monitor port)
This 8-channel CWDM MUX/DEMUX is a passive wavelength division multiplexing solution designed for dual-fiber transmission in point-to-point networks. It supports wavelengths from 1470nm to 1610nm with 20nm channel spacing and includes a dedicated 1310nm port for legacy services as well as a monitor port.
The unit is delivered as a plug-in LGX module and can be installed in a 4-slot 1U 19-inch rack chassis. It is ideal for environments where fiber resources are limited and bandwidth expansion is required without deploying additional fibers.
Typical applications include broadcast and television, data centers (IDC), finance, government networks, cloud infrastructure, and large-scale data transport.
