Questions & Answers

  • Does this 1G CWDM module support 1.25G rates?
    Yes, the actual rate of 1G CWDM SFP is 1.25 Gbit/s.
  • What is the power budget of the CWDM module #102530?
    The TX power ranges from -2 to 3dBm, and the Receiver Sensitivity is less than -32dBm. The power budget of the module equals the minimum transmit optical power minus the receiver sensitivity, which is -2 - (-32) = 30dB.
  • I need CWDM SFP modules that are compatible with my juniper switch, could you please recommend a model?
    Check #101627. Please select the reach (80km/120km) and wavelength according to your needs.
