minimum allowed input average optical

power for the PMD at the AI as defined

in Figure 10. (The input optical power

is averaged over a period of 1 µs or

more).

20. The high_light (Signal Detect) output

shall be asserted within 100 µs after a

step increase of the Input Optical

Power. The step will be from a low

Input Optical Power ≤ –45 dBm, into

the range between greater than Pm

and (Pm + 4 dB). Pm is the relevant

minimum allowed input average

optical power for the PMD at the AI as

defined in Figure 10. (The input

optical power is averaged over a

period of 1 µs or more).

21. This value is measured during the

transition from high to low levels of

input optical power. The maximum

value will occur when the input optical

power is –45 dBm average or when the

input optical power yields a BER of 10-

2 or better, whichever power is higher.

22. The low_light (Signal Detect) output

shall be deasserted within 350 µs after

valid IEEE 802.12 optical signals cease

to be present at the AI and the input

average optical power at AI has fallen

monitonically from a level between (Pm

+4 dB) and Pm to a level below –45

dBm and remain below –45 dBm (see

Figure 10). (The input optical power is

averaged over a period of 1 µs or

more.)

22. The low_light (Signal Detect) output

shall be deasserted within 350 µs after

valid IEEE 802.12 optical signals cease

to be present at the AI and the input

average optical power at AI, has fallen

monitonically from a level between

(Pm +4 dB) and Pm to a level below –

45 dBm and remain below –45 dBm

(see Figure 10). (The input optical

power is averaged over a period of 1

µs or more.)

23. Systematic Jitter (SJ) contributed by

the 800 and 1300 nm transmitter is a

combination of Duty Cycle Distortion

(DCD) and Data Dependent Jitter

(DDJ).

24. Random Jitter contributed by the 800

and 1300 nm transmitter is specified

with an IDLE Line State, 125 MBd

(62.5 MHz square-wave), input signal.
