Very High Performance OTDR APL-2+AOR502T2C test on a 1x4 splitter + 21km link, using 500ns pulse width, at 1310, 1550, 1625nm, with very low noise of 0.02dB.

The Need for Dynamic Range in OTDR’s

The required Signal/Noise Ratio (SNR) to the total link loss determines the dynamic range (SNR=1) required.

NOTE the dynamic range varies with the pulse width.

OTDR Index of Refraction (IOR) settings

  • Telstra: 1.4682 for 1310/1550/1625nm

  • NBN: 1310nm / 1.4672, 1625nm / 1.4683

  • TPG: 1310nm / 1.4677, 1550nm / 1.4682

3 File Saving Methods

  • Auto: automatically save after a test is completed

  • Semi Auto: user decides by press 'Save/File', (useful if the fibre link needs retesting)

  • Off: go through file naming, folder selection, and 'Save'

Use External Memroy Storage

  • At 'OTDR settings', 'Other set', set 'Auto save' to Off

  • After a test, press 'Save/File', do the file naming, select 'Save path Udisk'

  • Press 'Save'

  • Go back to 'OTDR settings', 'Other set', select either 'Auto' or 'Semi Auto'
