Product Description
GB1310/1550-SFP-LC/SC.S10 series is small form factor pluggable module for Gigabit Ethernet
1000BASE-BX and Fiber Channel single fiber applications by using 1310nm / 1550nm transmitterand 1550nm / 1310nm receiver. It is with the SFP 20-pin connector to allow hot plug capability.
The transmitter section uses a multiple quantum well A type / B type laser and is a class 1 laser
compliant according to International Safety Standard IEC 60825. The receiver section uses anintegrated B type / A type detector preamplifier (IDP) mounted in an optical header and a limiting
post-amplifier IC.
GB1310/1550-SFP-LC/SC.S10 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 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 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 a 4.7K –-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 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) 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 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.
TD-/+: These are the differential transmitter inputs. They are AC-coupled, differential lines with 100Ωdifferential termination inside the module. The AC coupling is done inside the module and is thus not
required on the host board.

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 thatare 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
are organized 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. Thetransceiver 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 9.3.
