To manage bandwidth and expand capacity of existing fiber optic backbones, Wavelength Division Multiplexing (WDM) works by simultaneously combining and transmitting multiple signals at different wavelengths in the same fiber.

A key advantage of WDM is that it is protocol and bit-rate independent. WDM-based networks can transmit data in IP, ATM, SONET/SDH, and Ethernet, and handle bit rates between 100 Mb/s and 40 Gb/s. Therefore, WDM-based networks can carry different types of traffic at different speeds over an optical channel. It creates a less costly method of quick response to customers’ bandwidth demands and protocol changes.

Tengiga provides a broad range of products for Long-haul/Metro/Access WDM applications including thin-film filter based Mux/Demux, OADM modules, planar waveguide based Arrayed Waveguide Gratings (AWG) and Interleavers.  All these products are protocol and bit-rate independent.  And they can be configured and integrated with other modules to meet various customized requirements.
