1)

Average optical power at which the BER is 1x10

2)

Fibre Channel PI Standard.

3)

Measured at the given Stressed Receiver Eyeclosure Penalty and DCD component given in Fibre Channel PI

Standard (2.03/2.18 dB & 40/80 ps).

4)

Measured according to IEEE 802.3

5)

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.

6)

A decrease in optical power below the specified level will cause the Signal Detect to change from a high state

to a low state.

7)

AC/AC for data. Load 50

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

should be added.

8)

Supply current excluding Rx output load.
