Low Loss Compact CWDM Demux , Compact Coarse Wavelength Division
Multiplexer
Description:
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.
Features:
- Low Insertion Loss
- High isolation
- Low Polarization Dependent Loss
- Compact design
- Good channel-to-channel uniformity
