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)

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.
