Notes:
1) Minimum average optical power at which the BER is less than 1x10E–12 or lower. Measured with a 2⁷–1 NRZ
PRBS and ER = 9 dB. Output of single mode fiber 9 µm diameter.
2) An increase in optical power above the specified level will cause the Signal Detect output to switch from a low
state to a high state.
3) A decrease in optical power below the specified level will cause the Signal Detect to change from a high state
to a low state.
4) DC/DC, AC/DC for data. DC/DC, AC/DC, AC/AC PECL for Signal Detect. PECL compatible. Load is 50 Ω into
V_CC–2 V for data, 500 Ω to V_EE for Signal Detect. Measured under DC conditions. For dynamic measurements
a tolerance of 50 mV should be added. V_CC = 3.3 V/5 V. T_AMB = 25°C.
5) Max. output current high: –0.4 mA (drive current), max. output current low: +2 mA (sink current).
6) AC/AC for data. Load 50 Ω to GND or 100 Ω differential. For dynamic measurement a tolerance of 50 mV
should be added.
