Notes:
1. Circuit ground is internally isolated from chassis ground.
2. Laser output disabled on TDIS >2.0V or open, enabled on TDIS <0.8V.
3. Should be pulled up with 4.7k - 10 kohms 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. Rate select is not used
5. LOS is open collector output. Should be pulled up with 4.7k – 10 kohms on host board to a voltage between 2.0V
and 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.
6. AC Coupled
SFP Module EEPROM Information and Management
The SFP modules implement the 2-wire serial communication protocol as defined in the SFP
-8472. The serial ID information of the SFP modules and Digital Diagnostic Monitor
