Note: (1) Maximum Input Optical Power, Pmax is defined as the optical power when the variation of F.W.H.M. of the output waveform is less than 10%

compared with that of the low input; optical power level.

(2) No data is accompanied with each device.

(3) Optical characteristics are specified on the condition that single mode fiber is used as the optical source for testing.
