Notes:
6. See “Typical Operating Characteristics” for the graph that demonstrates how to choose a particular RLOSLVL for a particular LOS assert and its
associated de-assert amplitude.
7. This specification defines electrical hysteresis as 20log(LOS de-assert/LOS assert). The ratio between optical hysteresis and electrical hysteresis is
found to vary between 1.5 and 2, depending on the level of received power and ROSA characteristics.
