4. Amplifier in limiting mode. Input is a 200MHz square wave.

7. This specification defines electrical hysteresis as 20log (SD Assert/SD De-assert). The ratio between optical hysteresis and

electrical hysteresis is found to vary between 1.5 and 2, depending upon the level of received optical power and ROSA

characteristics. Based upon that ratio, the optical hysteresis corresponding to the electrical hysteresis range 2dB-4.5dB, as

shown in the AC characteristics table, will be 1dB-3dB.
