Compact Form Factor Coarse WDM Optical Modules

Product ManualManual
  • New
  • Bi-directional mux/demux of up to 16 wavelengths in the 1270nm to 1610nm spectrum (ITU-T G.694.2 compliant)
  • Expandable from 8 to16 channel systems
  • Passive design for any bit rate
  • Low insertion loss to conserve system power
  • High optical isolation for low crosstalk
  • Compatible with all Evertz series CWDM Mux and Demux (3400CWDM, 3405CWDM, 7705CWDM)
  • Compact design occupies only one slot in an Evertz 7700/7800 frame per card module
  • LC/UPC and LC/APC connector options
  • Fiber protector to prevent connector damage
  • Multi-channel transport of video, audio, data, control in fiber limited applications
  • Cost reduction exercises through fewer leased fibers
  • Studio and Facility extension/expansion
  • STL and TSL links
  • Signal aggregation for outdoor and event coverage
  • Signal aggregation for security and monitoring

*7706CWDM to be used ONLY in Single Mode Fiber applications
