Notes:
1) Minimum average optical power at which the BER is less than 1x10
–10
or lower. Measured with a 2
23
–1 NRZPRBS as
recommended by ANSI T1E1.2, SONET OC-3 and ITU-T G.957. BOL value –31 dBm max.
2) An increase in optical power of data signal above the specified level will cause the Signal Detect to switch from a low state to a
high state.
3) A decrease in optical power of data signal below the specified level will cause the Signal Detect to switch froma high state to a low
state.
4) DC/DC, PECL for Signal Detect, PECL compatible. Load is 50Ω into V
CC
–2 V for data, 510 Ω to V
EE
for SignalDetect. Measured
under DC conditions. For dynamic measurements a tolerance of 50 mV should be added.V
CC
= 3.3 V. T
