The module ground contacts, Tx GND abd Rx GND, shall be isolated frim the module case, that is, frame ground. 2. Tx Fault is an open collector/drain output that shall be pulled up with a 4.7kΩ ~ 10kΩ on the host board. Pull up voltage between 2.0V and VccT + 0.5V. When high, output indicates a laser fault of some kind. When low, output indicates normal operation. The LD output is not turned off in case of Tx Fault 3. Tx Disable is an input that is used to shut down the transmitter optical output. It is pulled up within the TRx with a 4.7kΩ ~ 10kΩ to VccT. 4. SDA and SCL should be pulled up with a 4.7kΩ ~ 10kΩ on the host board. The pull-up voltage shall be VccT. SCL is the clock line of 2-wire serial interface for serial ID. SDA is the data line of 2-wire serial interface for serial ID. 5. Mod_ABS is connected to Tx GND or Rx GND in the SFP+ module. The host may pull the contact up to Vcc on the host board with a resistor in the range 4.7 ~ 10kΩ. Mod_ABS is asserted high when the SFP+ module is physically absent from a host slot. In the SFP MSA (INF-8074i) this contact has the same function but is called MOD_DEF0. 6. RS0 and RS1 are module input rate select contacts and are pulled low to Tx GND with a >30kΩ resistor in the module. RS0 is an input hardware contact which optionally selects the optical receive data path rate coverage for an SFP+ module. RS1 is an input hardware contact which optionally selects the optical transmit path data rate coverage for the SFP+ module. These contacts can also be used for AS0 and AS1 if implementing SFF8079. RS1 is commonly connected to Tx GND or Rx GND in the classical SFP modules. The host needs to ensure that it will not be damaged if this contact is connected to Tx GND or Rx GND in the module. For logical definitions of RS0/RS1, see Section 2.5 of SFF-8431 Rev LOS is an open collector output. Shall be pulled up with a 4.7kΩ ~ 10kΩ on host board. Pull up voltage between 2.0 and VccR+0.3. Logic 0 indicates normal operation. 6

Also necessary is the dc bias circuit of each input and output by taking into account of ac coupling of data input ant output of SFP+ module. For the interface of host board devices, it is recommended to refer to the device vendor s data sheet. 11

12 9. Digital Diagnostic Monitoring and Serial ID Operation The information is accessed through the pin 4 (SDA), and pin 5(SCL) of the module. The device address used to read the Serial ID data is X(A0h), and the address to read the diagnostic data is X(A2h). The EEPROM Write Protect pin is internally tied to ground with no external access, allowing write access to the customer-writable field (bytes of address X). Address bytes are not write protected and may cause diagnostic malfunctions if overwritten. The information stored in the EEPROM, including the organization and the digital diagnostic information, is defined in the Small Form-Factor document SFF-8472 Rev. 10.4, dated January 30, Data Field Descriptions, and Serial ID Data and Map Address( X) (A0h) Serial ID Information: Defined by SFP MSA OE Solution Specific Information Address( X) (A2h) Alarm and Warning Limits Reserved for External Calibration Constants Real Time Diagnostic Information OE Solutions Specific Non-volatile, customer- Reserved for SFP MSA writeable, field-writeable OE Solutions Specific Information 9.2 Serial ID and Map: page A0h Address HEX Name of Fields Description 0 03 Identifier SFP 1 04 Ext.
