Loss of Signal Hysteresis
Notes:
1. Maximum input optical power must be limited to +0.5dBm to prevent overdriving the optical receiver.
2. Input Optical Modulation Amplitude (commonly known as sensitivity) requires a valid 8B/10B encoded input.
3. These average power values are specified with an Extinction Ratio of 6 dB. The loss of signal circuitry responds to valid 8B/10B encoded peak to

Notes:
1. Max Pout is the lesser of Class 1 safety limits (CDRH and EN 60825) or receiver power, max.
2. Into single-mode optical fiber.
3. Contributed DJ is measured on an oscilloscope in average mode with 50% threshold and K28.5 pattern. Contributed TJ is the sum of contributed

RJ and contributed DJ. Contributed RJ is calculated for 1x10
oscilloscope by 14. Per FC-PI-4 (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-4 maximum limits with
the worst case specified component jitter input.
