Note:
1. Average optical power shall be measured using the methods specified in
TIA/EIA-455-95.
2. Receiver sensitivity is informative. Stressed receiver sensitivity shall be
measured with conformance test signal for BER =1x 10
-12
3. Vertical eye closure penalty and stressed eye jitter are the test conditions for
measuring stressed receiver sensitivity. They are not the required characteristic 
of the receiver. 
4. Power budget is defined as the different between the Rx sensitivity and the Tx.
Output power of the interface.
5. Path penalty is intended as the power penalty of the interface between back-to-
back and the maximum applied dispersion.
8. DIGITAL DIAGNOSTIC FUNCTIONS
The following digital diagnostic characteristics are defined over the Recommended 
Operating Environment unless otherwise specified. It is compliant to SFF8472
