1. Insertion loss over operating wavelength range at ~23°C (excluding PDL and TDL).

2. Insertion loss change over the specified wavelength range.

3. Insertion loss change over the all input polarization states

1. Insertion loss over operating wavelength range at ~23°C (excluding PDL and TDL). For S-band product, add 0.1dB due to water absorption peak of fiber.

2. Insertion loss change over the specified wavelength range. For S-band product, add 0.1dB in WDL due to water absorption peak of fiber.

3. Insertion loss change over the all input polarization states.
