Table 6. Transmitter Optical Characteristics(TC = -40°C to 85°C, VccT, VccR = 3.3V ± 10%)
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 fiber.
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
5. In a network link, each component’s output jitter equals each component’s input jitter combined with each component’s contributed jitter.

Notes
1. Input Optical Modulation Amplitude (commonly known as sensitivity) requires a valid 8B/10B encoded input.
2. These average power values are specified with an Extinction Ratio of 6dB. The loss of signal circuitry responds to valid 8B/10B encoded peak to
