EEPROM Information
3. MOD-DEF 0,1,2 are the module definition pins. They should be pulled up with a 4.7k~10kΩ resistor on
4. LOS is an open collector output, which should be pulled up with a 4.7k~10kΩ resistor on the host board to
5. These are the differential receiver output. They are internally AC-coupled 100Ω differential lines which
6. These are the differential transmitter inputs. They are AC-coupled, differential lines with 100Ω
The SFP MSA defines a 256-byte memory map in EEPROM describing the transceiver’s capabilities,
standard interfaces, manufacturer, and other information, which is accessible over a 2 wire serial
interface at the 8-bit address 1010000X (A0h). The memory contents refer to Table 9.

MOD-DEF 0 is grounded by the module to indicate that the module is present
MOD-DEF 1 is the clock line of two wires serial interface for serial ID
MOD-DEF 2 is the data line of two wires serial interface for serial ID
a voltage between 2.0V and Vcc+0.3V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.
In the low state, the output will be pulled to less than 0.8V.
