Notes:
1. Max Pout is the lesser of 0 dBm or Maximum allowable per Eye Safety Standard.
2. An OMA of 156 is approximately equal to an average power of –10 dBm assuming an Extinction Ratio of 9 dB.
3. Contributed DJ is measured on an oscilloscope in average mode with 50% threshold and K28.5 pattern.
4. Contributed RJ is calculated for 1E-12 BER by multiplying the RMS jitter (measured on a single rise or fall edge) from the oscilloscope by 14. Per
the FC-PI standard (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.
5. In a network link, each component’s output jitter equals each component’s input jitter combined with each component’s contributed jitter.
Contributed DJ adds in a linear fashion and contributed RJ adds in a RMS fashion. In the Fibre Channel specification, there is a table specifying the
input and output DJ and TJ for the transmitter at each data rate. In that table, RJ is found from TJ – DJ, where the TX input jitter is noted as Delta
T, and the TX output jitter is noted as Gamma T. The HFBR-59L1AL contributed jitter is such that, if the maximum specified input jitter is present,
and is combined with our maximum contributed jitter, then we meet the specified maximum output jitter limits listed in the FC-PI MM jitter
specification table.
6. Please refer to the HFBR-59L1AL characterization report for typical values.
