Product Description

1270nm 1330nm 4 6 8 Channel CCWDM With Low Polarization Dependent Loss


4 channels Compact CWDM 1270-1330 wavelength low insertion loss




Seacent Photonics offers compact CWDM modules that have a free-space structure and provide high optical performance. They come in a small-sized package and have extremely low insertion loss. These features help to significantly reduce optical power budgets for various applications. Additionally, these modules enable datacom or telecom network applications to use low-cost uncooled lasers, which also contributes to their cost-effectiveness.

These modules are available in configurations ranging from 4 to 18 channels, making them suitable for expanding the bandwidth of any network. As a single component serving as both a Mux and a Demux, the CCWDM also simplifies inventory management and can be used in the head end for outside plant.

The versatile and easy-to-install compact CWDM module provides a simple and cost-effective solution for expanding bandwidth and increasing revenue from existing optical fiber.


Compact Coarse Wavelength Division Multiplexing (CCWDM) is the use of the Fiber Optical Multiplexer to different wavelengths of light signals multiplexed to a single optical fiber for transmission, at the receiving end of the link, with the Fiber Optical Multiplexer fiber mixed signal is decomposed into different wavelengths signal, connected to the respective receiving device
