Notes:
1. Max Pout is the lesser of Class 1 safety limits (CDRH and EN 60825) or receiver power, max.
2. Into 50/125um (0.2 NA) multi-mode optical ber.
3. Contributed DJ is measured on an oscilloscope in average mode with 50% threshold and K28.5 pattern.
4. 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.
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.

Notes
1. Input Optical Modulation Amplitude (commonly known as sensitivity) requires a valid 8B/10B encoded input.
2. These average power values are specied with an Extinction Ratio of 9dB. The loss of signal circuitry responds to valid 8B/10B encoded peak to
peak input optical power, not average power.
