The Fiberroad’s DWDM Passive MUX/DeMUX modules deliver the benefits of a Dense Wave Division Multiplexer in a fully passive solution. With matching MUX/DeMUX units placed at each end of an optical link,up to 16 channels can be combined and transmitted over a single-mode fiber trunk. As they operate independent of protocol and topology, these passive components remain transparent to both the network and the end user. With plug-n-play setup and a design that minimizes budget loss, they can readily and seamlessly integrate into an existing environment. Their small form factor and no power requirement means they can be placed virtually anywhere. Fiberroad‘s DWDM Mux/Demux is used to provide transport solution for DWDM networking system. The Fiberroad‘s Fiber Driver Passive MUX/DeMUX modules are available with 2, 4, 8, or 16 independent wavelengths. Each single-slot highdensity module installs in any Fiberroad‘s chassis. A powered chassis is required only for managed applications.
