4CH CWDM MUX/DEMUX Dual Fiber 1U Rack Mount

The 4 channel CWDM passive MUX DEMUX modules deliver the benefits of a Coarse Wave Division Multiplexer in a fully passive solution.With matching MUX DEMUX units placed at each end of an optical link, up to 4 data channels can be combined and transmitted over a single-mode fiber trunk.

It covers all channels from 1270nm to 1610nm in 20nm increments

Features

  • Multiplexing of up to 4 channels on a fiber pair
  • Low Insertion Loss
  • Wide passband
  • High Channel Isolation
  • High Stability and reliability
  • 1U 19´´ low profile modular design
  • Compliant to ITU-T G.694.2 standard and Telcordia GR1209, GR1221
  • Standard 18-channel CWDM band 1270 nm - 1610 nm, 20 nm spacing
  • Based on thin-film filter technology
  • Passive, no electric power required. (MTBF ca. 500 years)

 

Applications

  • CWDM transmission
  • Metro and long-haul networks
  • Point-to-point CWDM fiber optimization
  • Linear add/drop CWDM fiber optimization
