dB

1)

Minimum average optical power at which the BER is less than 1x10E–12 or lower. Measured with a 2

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

W into

a tolerance of 50 mV should be added.

Max. output current high: –0.4 mA (drive current) low: +2.0 mA (sink current)

6)

AC/AC for data. Load 50

W to GND or 100 W differential. For dynamic measurement a tolerance of 50 mV

should be added.
