The CWDM Active 16-Channel Wavelength Division Multiplexer is a carrier-class optical communication device built on coarse wavelength division multiplexing technology, featuring multi-channel integration and built-in active amplification capabilities. Simply put, it is a device which allows the user to combine up to 16 sources of data on a single fiber pair. Each channel can be linked via fiber with selected FiberPlex FOM, FOI or TD Series fiber modules, FiberPlex LightViper™ or with virtually any third-party fiber optic equipment with data rates from 50 Mbps up to 3. Wavelength Division Multiplexing (WDM) plays an important role in optical interconnection.
