Product Description
SHARETOP’S Coarse Wavelength Division Multiplexer (CWDM) devices demonstrate low loss and reliable performances. It can not only increase efficiency, but also reduce costs
These devices show broad passband and high isolation, making them ideal for operation with inexpensive, uncooled lasers. They are low cost products for the CATV and metro/access markets.Easily customizable, SHARETOP’S CWDM can be configured from a standard list of packaging and connector options.
Features
Low insertion loss
High channel isolation
Low polarization dependent loss
Exceptional reliability and stability
Applications
Access networks
Metro WDM Systems
Enterprise networks
