5EEPROM Section
The optical transceiver contains an EEPROM. It provides access to sophisticated identification information that describes the transceiver’s capabilities, standard interfaces, manufacturer, and other information.
The Module provides diagnostic information about the present operating conditions. The transceiver generates this diagnostic data by digitization of internal analog signals. Calibration and alarm/warning threshold data is written during device manufacture. Received power monitoring, transmitted power monitoring, bias current monitoring, supply voltage monitoring and temperature monitoring all are implemented. The diagnostic data are raw A/D values and must be converted to real world units using calibration constants stored in EEPROM locations 56 -95 at wire serial bus address A2h. The digital diagnostic memory map specific data field defines as following.

Notes:
1. TX Fault is an open collector output, which should be pulled up with a 4.7k~10kΩ resistor on the hostboard to a voltage between 2.0V and Vcc+0.3V. Logic 0 indicates normal operation; logic 1 indicates a laser fault of some kind. In the low state, the output will be pulled to less than 0.8V.
2. TX disable is an input that is used to shut down the transmitter optical output. It is pulled up within the module
with a 4.7–10 KΩ resistor.It’s states are:
Low (0 – 0.8V):Transmitter on
(>0.8, < 2.0V):Undefined
High (2.0 – 3.465V):Transmitter Disabled
Open:Transmitter Disabled.
3. SDA and SCL is communication interface for I2C . They should be pulled up with a 4.7K – 10KΩ resistor on the host board. The pull-up voltage should be VccT or VccR.
4. LOS (Loss of Signal) is an open collector/drain output, which should be pulled up with a 4.7K – 10KΩ resistor. Pull up voltage between 2.0V and VccR+0.3V. When high, this output indicates the received optical power is below the worst-case receiver sensitivity (as defined by the standard in use). Low indicates normal operation. In the low state, the output will be pulled to < 0.4V.
5. VeeR and VeeT may be internally connected within the SFP+ module
6. RD-/+: These are the differential receiver outputs. They are AC coupled 100Ω differential lines which should be
terminated with 100Ω (differential) at the user SERDES. The AC coupling is done inside the module and is thus
not required on the host board.
7. VccR and VccT are the receiver and transmitter power supplies. They are defined as 3.3V ±5% at the SFP+ connector pin. Maximum supply current is 45 in order to maintain the required voltage at the SFP+ input pin with 3.3V supply voltage. Vcc is internally connected inside the BIDI transceiver.
8. TD- and TD+ are the differential transmitter inputs. They are AC coupled differential lines with 100 Ω differential termination inside the module. The AC coupling is done inside the module and is thus not required on the host board.
