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. 


  • 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 


  • Telecommunications
  • Enterprise networks
  • Metro WDM systems
