Notes:
1. Max Pout is the lesser of Class 1 safety limits (CDRH and EN 60825) or receiver power, max.
2. Into 50/125 µm (0.2 NA) multimode optical fiber.
3. An OMA of 156 is approximately equal to an average power of –10 dBm assuming an Extinction Ratio of 9 dB.
4. Contributed DJ is measured on an oscilloscope in average mode with 50% threshold and K28.5 pattern.
5. Contributed RJ is calculated for 1x10
-12
BER by multiplying the RMS jitter (measured on a single rise or fall edge) from the oscilloscope by 14. Per
FC-PI (Table 13 - MM 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.
6. IEEE 802.3.
7. Measured at TP2. TP refers to the compliance point specified by IEEE 802.3, section 38.2.1.
