Note1. If : LD forwad current
Note2. Detailed test condition:
Total loss includes the fiber loss. (Please see 'Type vs. performance'.)
Receiver responsively = 0.9A/W
Input equivalent noise current = 7pA(Hz)1/2
Optical return loss of the connector should be greater than 40dB in order to get the specification performance.
Note3. Relative intensity noise does not include shot noise of receiver.
Note4. Er = MAX | 10*log(Pf/Pf(25°C))|
