Compact CWDM Modules (Compact Course Wavelength Division Multiplexers, or Low Loss CCWDM)

Lfiber’s mini / 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 compact CWDM module 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 provides a simple and low-cost method for expanding bandwidth and increasing revenue from existing optical fiber.
