Description
Sufficient optical signal for potential BER < 1x10
Insufficient signal for potential BER < 1x10
This pin is open collector compatible, and should be pulled up
to Host V
These pins should be connected to signal ground on the host board.
The V
and are isolated from the module case.
Light on = Logic “0” Output
Receiver DATA output is internally AC coupled and series
terminated with a 50 W resistor.
Light on = Logic “1” Output
Receiver DATA output is internally AC coupled and series
terminated with a 50 W resistor.
This pin should be connected to a filtered +3.3 V power supply
on the host board. See Application schematics on page 4 for
filtering suggestions. The pin is connected inside the module
to pin 16 V
This pin has an internal 30 kW pull-down to ground. A signal
on this pin will not affect module performance.
Logic “1” Input (or no connection) = Laser off
Logic “0” Input = Laser on
This pin is internally pulled up to V
These pins should be connected to signal ground on the host board.
The V
and are isolated from the module case.
Logic “1” Output = Laser Fault (Laser off before t_fault)
This pin is open collector compatible, and should be pulled up
to Host Vcc with a 10 kW resistor.
This pin should be connected to a filtered +3.3 V power supply
on the host board. See Application schematics on page 4 for
filtering suggestions. The pin is connected inside the module
to pin 15 V
Logic “1” Input = Light on
Transmitter DATA inputs are internally AC coupled and
terminated with a differential 100 W resistor.
Logic “0” Input = Light on
Transmitter DATA inputs are internally AC coupled and
terminated with a differential 100 W resistor.
This pin has an internal 30 kW pulldown to ground. A signal
on this pin will not affect module performance.
Serial ID with SFF 8472 Diagnostics.
Module definition pins should be pulled up to Host Vcc with
appropriate resistors for the speed and capacitive loading of the
bus. See SFF8431.
