Tier 1 - Optical Loss Testing

Tier 1 Certification - Optical Loss Testing 
In its simplest form and optical loss testing is a comparison between the optical power measured in dBm at the output of the light source and the power measured at the far end of a fiber connected to that same light source. The difference is known as loss or attenuation, expressed in dB.
Combining the light source/power meter, measuring against standards and providing a pass/fail is known as an Optical Loss Test Set.

Tier 2 Testing

TIA-568: Optical Fiber Cabling and Components Standard
Tier 2 testing supplements Tier 1 testing with the addition of an OTDR characterization of the elements along the fiber cabling.
Simply put, Tier 2 is just testing the same fiber with an OLTS and an OTDR and documenting the results of both.
