Notes:

1. Average power figures are informative only, per IEEE802.3ae.

2. TWDP figure requires the host board to be SFF-8431 compliant. TWDP is calculated using the

Matlab code provided in clause 68.6.6.2 of IEEE802.3ae.

3. 12dB reflection.

4. Conditions of stressed receiver tests per IEEE802.3ae. CSRS testing requires the host board to be

SFF-8431 compliant.

5. Receiver overload specified in OMA and under the worst comprehensive stressed condition.
