Product Description
The IDXXXX-SFP-LC.S80 series single mode transceivers is small form factor pluggable module
for bi-directional serial optical data communications such as SONET OC-48 / SDH STM-16 /OC-12 / OC-3, Gigabit Ethernet 1000BASE, Fibre Channel 1x/2x SM-LC-L FC-PI. It is with theSFP 20-pin connector to allow hot plug capability.
This module is designed for single mode fiber and operates at a nominal wavelength of CWDM
wavelength. There are eighteen center wavelengths available from 1270nm to 1610nm, witheach step 20nm.
The transmitter section uses a multiple quantum well CWDM DFB laser and is a class 1 laser
compliant according to International Safety Standard IEC-60825. The receiver section uses anintegrated InGaAs detector preamplifier (IDP) mounted in an optical header and a limiting
post-amplifier IC.
The IDXXXX-SFP-LC.S80 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 Disabled3) Mod-Def 0,1,2. These are the module definition pins. They should be pulled up with a 4.7K –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

CWDM SFP Series
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 ID4) 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 thestandard 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 isdone inside the module and is thus not required on the host board. The voltage swing on theselines will be between 400 and 2000 Mv differential (200 –1000 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 beused in order to maintain 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 transceivermodule will result in an inrush current of no more than 30Ma greater than the steady state value.
VccR and VccT 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 andis thus not required on the host board. The inputs will accept differential swings of 400 – 2000Mv(200 – 1000Mv single-ended).

CWDM 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 writing protected within the SFP transceiver. The negative edge clocks data from the SFPtransceiver. 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 orsequentially.
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 powermonitoring, transmitted power monitoring, bias current monitoring, supply voltage monitoring andtemperature monitoring all are implemented. If the module is defined as external calibrated, thediagnostic 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.
