MT-RJ to MT-RJ fiber testing with the SimpliFiber Pro

The following article describes how to test an MT-RJ to MT-RJ fiber link using a modified (adapted) TIA/EIA Method B for Multimode and TIA/EIA Method A.1 for Singlemode. It is not possible to use a "1 jumper reference method" when testing MT-RJ to MT-RJ links.

You will need:

SimpliFiber Pro Required Test Tools 

  • Power on the SimpliFiber Pro Source.
  • Press the AUTO key on the SimpliFiber Pro Source .
  • In AUTO mode, the SimpliFiber Pro Source will tell the SimpliFiber Pro Meter which wavelength it is transmitting at. This allows both wavelengths to be measured at the same time.

  • Leave the SimpliFiber Pro Source to stabilize for at least 5 minutes.
  • While the SimpliFiber Pro Source is stabilizing, clean and inspect your test reference cords.
  • Connect your test reference cord as shown below, making sure the fiber size is the same as the link you are about to test.

  • Press the Mode key until you see LOSS in the upper right hand screen (shown below).

  • Press the F3 key once to set the reference. When you see OK appear, the reference has been set for both wavelengths.
  • If the SimpliFiber Pro Source has been allowed to stabilize fully, you should see 0.00 dB as shown below:

  • If you start to see it change from 0.00 dB, it means the SimpliFiber Pro Source has not been allowed to stabilize. Wait until the reading stabilizes, then press the F3 key again to reset the reference.
  • Remove the reference patch cords from the adapter.

  • Add a known good short test reference cord. This is needed so that you have a pinned patch cord at each end. If you do not do this, you will have very high losses.

  • Connect to the fiber link to be tested.

  • The SimpliFiber Pro Meter will then automatically measure the loss at both wavelengths.
  • Press the F1 key to save the test result. It will save both wavelengths as one record.
  • CAUTION: Do not disconnect the fiber from the SimpliFiber Pro Source to measure the other fiber. You will need to test all of your strand As, then reset the reference to test your strand Bs.
