CCWDM Applied in LTE

CCWDM is an integrated optical module using free-space optics platform which can significantly improve optical performance, while reducing manufacturing costs, in a package less than 1/4 the size of conventional CWDM modules. 


With a channel spacing of 20 nm and wide bandpass characteristics, it can be used for datacom / telecom network applications using low-cost uncooled lasers. The CCWDM is available in 4/8/10 channels with an extended port channels. 


   Features:

   Ultra-Low insertion loss (<1.3dB ) & Low PDL

   Wide pass band & High channel Isolation

   Good Channel Uniformity

   Compact Size( 45x325x6mm) 

   Exceptional reliability and stability

   Telcordia GR-1221/1209-CORE Compliant 


   Applications:

   Telecommunications

    Enterprise networks

    Metro WDM systems

    LTE Mobile System
