General Specification Considerations (Notes):

1. IEEE 802.3ae Clause 52 compliant.

2. Vertical eye closure and stressed eye jitter are test conditions for stressed sensitivity (OMA) measurements.

3. Loss of Signal (LOS) detection responds only to OMA and the indicator will respond unpredictably with the application of unmodulated optical

power.
