CWDM Chips


Broadex Technologies PLC-based CWDM chips are used in the latest state-of-the-art transceivers to multiplex and demultiplex wavelength channels. They provide high bit rate connections over a single fiber pair.  We have a long history of successfully manufacturing CWDM chips in high volume, having made tens of thousands of complicated CWDM devices.

These chips can be offered as individual AWGs or monolithic chips that feature a mux/demux pair and other features such as taps, loopbacks and monitor channels can also easily be added.  Broadex can supply CWDM products with numerous form factors: wafer level, bare diced, fiber attached, connectorized and with 40-50 degree waveguide polishing for flip chip integration with silicon photonics engines.  

Broadex Technologies CWDM chips can also be supplied as packaged and connectorized modules for use in access and campus networks.
