Table 7. Receiver Optical Characteristics
Notes:
1. BER = 10
2. An average power of -20 dBm with an Extinction Ratio of 9 dB is approximately equivalent to an OMA of 15 μW.
3. These average power values are specified with an Extinction Ratio of 9 dB. The loss-of-signal circuitry responds to valid 8B/10B-encoded peak
Table 6. Transmitter Optical Characteristics
Notes:
1. Class 1 Laser Safety per FDA/CDRH
2. Contributed total jitter is calculated from DJ and RJ measurements using TJ = RJ + DJ. Contributed RJ is calculated for 1x10-12 BER by
3. Eye shall be measured with respect to the mask of the eye using filter defined in IEEE 802.3 section 38.6.5

multiplying the RMS jitter (measured on a single rise or fall edge) from the oscilloscope by 14. Per FC-PI (Table 9 - SM jitter output, note 1), the
actual contributed RJ is allowed to increase above its limit if the actual contributed DJ decreases below its limits, as long as the component
output DJ and TJ remain within their specified FC-PI maximum limits with the worst case specified component jitter input.
