Circuit ground is internally isolated from chassis ground.
Laser output disabled on T
Should be pulled up with 4.7 k - 10 kohms on host board to a voltage between 2.0 V and 3.6 V.
MOD_DEF(0) pulls line low to indicate module is plugged in.
Transceivers operate at 1G and 2G Fibre Channel, and Gigabit Ethernet data rates and respective protocols without active
control.
LOS is open collector output. Should be pulled up with 4.7k – 10 kohms on host board to a voltage between 2.0 V and 3.6 V.
Logic 0 indicates normal operation; logic 1 indicates loss of signal.
