  • Dual-port and pass-through design
  • Ten groups threshold can be selected
  • Three indicator display the optical path state.
  • USB interface store 99 records in tester
  • Test power value of 1490nm, 1550nm and 1310nm in PON system at the same time.
  • Test burst mode of 1310nm up wavelength

a special tester to test FTTx/PON passive optical network

  • It can synchronously measure voice, data and video signal on BPON/EPON/GPON framework.
  • It can set the power threshold and indicate the pass, alarm and fail of every wavelength.
  • It can be set threshold, upload data and calibrate wavelength.
  • It can be set from 5 to 60 minutes or none to power off automatically


  • FTTx/PON open: test all PON signal during openning to prove that match the network standard.
  • FTTx/PON maintenance: test the transmission performance in daily maintenance.
  • It can easily evaluate power value of any position in network which is from OLT to ONT.
