Telecommunications CCWDM Mux Demux Wide Operating Wavelength Range


Coarse Wavelength Division Multiplexing (CWDM) is an excellent choice for increasing bandwidth capacity while keeping costs down.

Seacent Photonics compact CWDM Modules feature free-space structure, high optical performance, small-sized package, and extremely low insertion loss. With these features, they dramatically relax the optical power budgets for your applications, allow datacom or telecom network applications to use low-cost uncooled lasers, and function in small-sized packages. Available from 4 to 18 channel configurations, the CCWDM can meet the expansion needs of any network. The module also simplifies inventory management since the same component serves as both a Mux and a Demux and can be used in the head end for outside plant. Compact and easy to install, the versatile compact CWDM module provides a simple and low-cost method for expanding bandwidth and increasing revenue from existing optical fiber.
