The differences between EPON SFP PX20 and PX20+

For EPON SFP Module, buyers usually ask that what is the difference between EPON OLT/ONU SFP PX20&PX20+.  Here below can give you some hints:

Firstly, the main differences are Output power and Receiver sensitivity.

  • Item
  • Average output power (MAX)
  • Average output power (MIN)
  • Receiver Sensitivity (MAX)
  • PX20 OLT
  • 7dBm
  • 2dBm
  • -27dBm
  • PX20 ONU
  • 4dBm
  • -1dBm
  • -24dBm
  • PX20+ OLT
  • 7dBm
  • 2.5dBm
  • -30dBm
  • PX20+ ONU
  • 4dBm
  • 0dBm
  • -27dBm

Then, as we all know, a PON’s distinguishing feature is that it implements a point-to-multipoint architecture, so in terms of Splitting ration and Transmission distance, there also exist some differences, and PX20+ types performance better:

  • Type
  • PX20
  • PX20+
  • 1:8
  • 20KM
  • 20KM
  • 1:16
  • 20KM
  • 20KM
  • 1:32
  • 10KM
  • 20KM
  • 1:64
  • 10KM
