In light of item 5 in RoHS exemption list of RoHS Directive 2002/95/EC, Item 5: Lead in glass of cathode ray tubes,
electronic components and fluorescent tubes.
In light of item 13 in RoHS exemption list of RoHS Directive 2005/747/EC, Item 13: Lead and cadmium in opticaland filter glass. The three exemptions are being concerned for our transceivers, because our transceivers use glass,which may contain Pb, for components such as lenses, isolators, and other electronic components.

Note 5Notes:1) TX Fault is an open collector/drain output, which should be pulled up with a 4.7K – 10KΩ resistoron the host board. Pull up voltage between 2.0V and VccT/R+0.3V. When high, output indicates alaser fault of some kind. Low indicates normal operation. In the low state, the output will be pulledto < 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 4.7K – 10 KΩ resistor. Its states are:
Low (0 – 0.8V): Transmitter on(>0.8, < 2.0V): UndefinedHigh (2.0 – 3.465V): Transmitter Disabled
Open: Transmitter Disabled
3) Module Absent, connected to VeeT or VeeR in the module.
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 VccT/R+0.3V. When high, this output indicatesthe 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 < 0.8V.
5) The module signal ground contacts, VeeR and VeeT, should be isolated from the module case.

Page 6 of 9SFP+ BIDI Series6) 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. The voltage swing on these lines will
be between 350 and 700 mV differential (175 –350 mV single ended) when properly terminated.
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 300mA. Recommended host board power
supply filtering is shown below. Inductors with DC resistance of less than 1 ohm should be used inorder to maintain the required voltage at the SFP+ input pin with 3.3V supply voltage. When therecommended supply-filtering network is used, hot plugging of the SFP+ transceiver module will
result in an inrush current of no more than 30mA greater than the steady state value. VccR andVccT may be internally connected within the SFP+ transceiver module.
8) TD-/+: These are the differential transmitter inputs. They are AC-coupled, differential lines with100Ω differential termination inside the module. The AC coupling is done inside the module and isthus not required on the host board. The inputs will accept differential swings of 150 – 1200 mV (75– 600mV single-ended).

EEPROM
The serial interface uses the 2-wire serial CMOS EEPROM protocol defined for the ATMEL
AT24C02/04 family of components. When the serial protocol is activated, the host generates theserial clock signal (SCL). The positive edge clocks data into those segments of the EEPROM thatare not writing protected within the SFP+ transceiver. The negative edge clocks data from theSFP+ transceiver. The serial data signal (SDA) is bi-directional for serial data transfer. The hostuses SDA in conjunction with SCL to mark the start and end of serial protocol activation. The
memories are organized as a series of 8-bit data words that can be addressed individually orsequentially.
The Module provides diagnostic information about the present operating conditions. The
transceiver generates this diagnostic data by digitization of internal analog signals. Calibration andalarm/warning threshold data is written during device manufacture. Received power monitoring,transmitted power monitoring, bias current monitoring, supply voltage monitoring and temperaturemonitoring all are implemented. If the module is defined as external calibrated, 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 define as following .For detail EEPROM information, please refer to the related
document of SFF 8472 Rev 10.2.
