8CH CWDM, 1270-1450nm (Except 1390, 1410) Dual Fiber, LC/UPC

Conventional ITU-T G.652 single-mode fibers show the significant attenuation around 1400nm caused by the water absorption peak, thus the 1390 and 1410 wavelengths are not used due to the higher attenuation.

  • Passive Transparent Any Rate, Any Service Multiplexing
  • Multiplexing of up to 8 Channels on Fiber Pair to Maximize the Using of Existing Fiber
  • Low Insertion Loss: Typical 2.5dB, Max 3.0dB(TFF)
  • Compliant with All Optical Networking Products (ITU Grid)
  • Applied to Metro, Regional and CWDM Networks
  • The Solution Can be Customized per Customer Application Requirements
