18CH CWDM, 1270nm-1610nm, Dual Fiber, LC/UPC, 1U Rack Mount

CWDM technology provides the flexibility to increase capacity of existing fiber infrastructure by enabling multiple channels/wavelengths over the same fiber cabling. Each channel carries data independently from each other, allowing network designers to transport different data rates. It’s protocol and rate transparent supporting such applications as 1G/10G Ethernet, SDH/SONET and 8/4/2/1G Fiber Channel across the same fiber link.

  • Passive Transparent Any Rate, Any Service Multiplexing
  • Multiplexing of up to 18 Channels on Fiber Pair to Maximize the Using of Existing Fiber
  • Low Insertion Loss: Typical 5.0dB, Max 5.5dB (TFF); Typical 2.2dB, Max 2.5dB (Free Space)
  • Compliant with All Optical Networking Products (ITU Grid)
  • Monitor Port Taps off 1% of the Signal to Monitor the Channel Power Levels
  • Hybrid C/DWDM System via 1530nm/1550nm for Additional DWDM Channels
  • The Solution Can be Customized per Customer Application Requirements
