 STEP 2: SINGLEMODE WAVELENGTHS?

Which singlemode wavelengths do you need?

OTDR test applications vary widely so there are a wide range of singlemode wavelength combinations available in our OTDRs.

Longer wavelengths - especially 1625nm and 1650nm - are more sensitive to macrobends and so these wavelengths are often included in OTDRs to enable macrobend detection.

Filtered 1625/1650nm options allow live-fibre/in-service testing (see Step 3.)

In Australia, the most common combinations are dual wavelength 1310/1550nm and triple wavelength 1310/1550/1625nm with the tri-wave variant used for most Telstra, Optus and NBN work.
