Wavelength division multiplexing, WDM. has long been the technology of choice for transporting large amounts of data between sites. It increases bandwidth by allowing different data streams to be sent simultaneously over a single optical fiber network. In this way WDM maximizes the usefulness of fiber and helps optimize network investments.

There are several advantages to using WDM. Individual wavelengths can be from a normal link so current equipment can be used. Laser transmitters must be chosen to match the WDM demultiplexer so each channel is properly decoded at the receiving end.
Future enhancements are expected to offer 80-128 channels.



  • Low insertion loss and excess loss
  • Excellent environmental stability
  • The ratio can be specify
  • Wide passing bands
  • High isolation between channels
  • Low insertion loss
  • High stability and reliability
