　　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.
