Note 1) Optical return loss of the connectors should be greater than 40dB in order to get the specified performance.
Note 2) Relative intensity noise dose not includes shot noise of receiver.
Note 3) Spurious noise is defined under the following test condition.
2-tone carrier frequency
: f1=13MHz, f2=19MHz
Fiber length
Measurement frequency
Spectrum analyzer setting
: 15km
: 5~200MHz
: Resolution bandwidth 100kHz, video bandwidth 30kHz and 30 second max hold.
Note 4) Er = MAX |10* log (Pf/Pf(25°C))|
Note 5) Relative differential efficiency is defined as the differential efficiency ratio to the differential efficiency at 25°C
