Module Ground
Optional –5.2 Power Supply – Not required
Module De-select; When held low allows the module to
respond to 2-wire serial interface commands
Interrupt (bar); Indicates presence of an important condition
which can be read over the serial 2-wire interface
Transmitter Disable; Transmitter laser source turned off
+5 Power Supply
Module Ground
+3.3V Power Supply
+3.3V Power Supply
Serial 2-wire interface clock
Serial 2-wire interface data line
Module Absent; Indicates module is not present. Grounded
in the module.
Module Not Ready; Finisar defines it as a logical OR
between RX_LOS and Loss of Lock in TX/RX.
Receiver Loss of Signal indicator
Module Ground

Receiver inverted data output
Receiver non-inverted data output
Module Ground
+1.8V Power Supply
Power Down; When high, places the module in the low
power stand-by mode and on the falling edge of P_Down
initiates a module reset
Reset; The falling edge initiates a complete reset of the
module including the 2-wire serial interface, equivalent to a
power cycle.
