Features

  • Cascadeable, bi-directional eight channel mux/demux modules
  • ITU-T G.694.1 compliant 0.8nm (100GHz) channel spacing
  • Capable of being inserted into CWDM 1550nm wavelength slot adding an additional 8 or 16 DWDM wavelengths to existing CWDM systems
  • Passive design for any bit rate
  • Low insertion loss to conserve system power
  • High optical isolation for low crosstalk
  • Fully hot swappable from front of frame with no fiber disconnect/reconnect required
  • SC/PC, FC/PC* connector options
  • Fiber protector to prevent connector damage

* 7705DWDM to be used ONLY in Single Mode Fiber applications

Applications
