Note 4)
Relative differential efficiency is defined as the differential efficiency ratio to the differential efficiency at 25°C.
Relative intencity noise does not include shot noise of receiver.
Optical return loss of the connectors should be greater than 40dB in order to get the specified performance.
Note 5) Spurious noise is defined under the following test conditions;
2 tone carrier frequency: f1=13MHz, f2=19MHz
Measurement frequency: 5 to 200MHz
Spectrum analyzer setting: Resolution bandwidth 100 kHz, video bandwidth 30 kHz and 30 second max. hold.
