Product Description
The GB1310/1550-SFP-SC.xx series is small form factor pluggable module for Gigabit Ethernet
1000BASE-BX and Fiber Channel single fiber applications by using 1310nm / 1550nm transmitter and1550nm / 1310nm receiver. It is with the SFP 20-pin connector to allow hot plug capability.
The transmitter section uses a distributed feedback laser and is a class 1 laser compliant according toInternational Safety Standard IEC 60825. The receiver section uses an integrated A type / B typedetector preamplifier (IDP) mounted in an optical header and a limiting post-amplifier IC.
The GB1310/1550-SFP-SC.xx series are designed to be compliant with SFF-8472 Multi-source
Agreement (MSA).

Notes:1) TX Fault is an open collector/drain output, which should be pulled up with a 4.7K – 10KΩ resistor on
the host board. Pull up voltage between 2.0V and VccT, R+0.3V. When high, output indicates a laser
fault of some kind. Low indicates normal operation. In the low state, the output will be pulled to < 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. Its states are:Low (0 – 0.8V): Transmitter on (>0.8,< 2.0V): UndefinedHigh (2.0 – 3.465V): Transmitter Disabled
Open: Transmitter Disabled
3) Mod-Def 0,1,2. These are the module definition pins. They should be pulled up with a4.7K –10Kresistor on the host board. The pull-up voltage shall be VccT or VccR .
Mod-Def 0 is grounded by the module to indicate that the module is present
Mod-Def 1 is the clock line of two wire serial interface for serial ID
Mod-Def 2 is the data line of two wire serial interface for serial ID
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 indicates thereceived 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) 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 300mA. Recommended host board power supply
filtering is shown below. Inductors with DC resistance of less than 1 ohm should be used in order tomaintain the required voltage at the SFP input pin with 3.3V supply voltage. When the recommended
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 and VccT may be internallyconnected 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.

BIDI SFP Series
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 that are
not write protected within the SFP transceiver. The negative edge clocks data from the SFP
transceiver. The serial data signal (SDA) is bi-directional for serial data transfer. The host uses SDA
in conjunction with SCL to mark the start and end of serial protocol activation. The memories areorganized as a series of 8-bit data words that can be addressed individually or sequentially.
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 powermonitoring, bias current monitoring, supply voltage monitoring and temperature monitoring all areimplemented. 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 asfollowing .For detail EEPROM information, please refer to the related document of SFF 8472 Rev 9.3.
