8 Channels 100GHz C21-C28, with Monitor, Expansion and 1310nm Port, LC/UPC, Dual Fiber, High Density DWDM Mux Demux, FHD Plug-in Module

The C21-C28 channel port for ITU grid DWDM traffic, EXP port for service expansion, MON port for optical performance monitoring.

Expansion port & 1310nm port make additional channels can be seamlessly added to increase capacity.

Instead of using multiple fibers for each service, a single fiber can be shared for multiple different data or services in WDM network. It maximizes the usefulness of fiber and generates substantial savings.

Usually, at a split of 1% (2%, 3%, 5% optional), the monitor port offers flexible monitoring ways to test the power, wavelength and OSNR of the optical signal without service interruption.
