3. Should be pulled up with 4.7k – 10kohms on host board to a voltage between 2.0V and 3.6V.
MOD_DEF(0) pulls line low to indicate module is plugged in.
4. Finisar FTLFxx21xxxxx transceivers operate between OC-3 and OC-48, 1x and 2x Fibre Channel, and
Gigabit Ethernet data rates and respective protocols without active control. Finisar FTRJxx19xxxxx
transceivers operate at 1x and 2x Fibre Channel, and Gigabit Ethernet data rates and respective
protocols without active control.
5. LOS is open collector output. Should be pulled up with 4.7k – 10kohms on host board to a voltage
between 2.0V and 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.
