use glass, which may contain Pb, for components such as lenses, windows, isolators, and other electronic
components.
Product Description
The SNR-SFP+LR-2 series single mode transceiver is small form factor pluggable module for
serial optical data communications such as IEEE 802.3ae 10GBASE-LR/LW. It is with the SFP+
20-pin connector to allow hot plug capability.
This module is designed for single mode fiber and operates at a nominal wavelength of 1310 nm.
The transmitter section uses a 1310nm multiple quantum well FP laser and is a class 1 laser
compliant according to International Safety Standard IEC-60825.
The receiver section uses an integrated InGaAs detector preamplifier (IDP) mounted in an optical
header and a limiting post-amplifier IC.

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 4.7K – 10 KΩ resistor. Its states are:
Low (0 – 0.8V): Transmitter on
(>0.8, < 2.0V): Undefined
High (2.0 – 3.465V): Transmitter Disabled
Open: Transmitter Disabled
3) Modulation 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 indicates
the 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. Inductors with DC resistance of
less than 1 ohm should be used 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+ transceiver module 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 with
100Ω differential termination inside the module. The AC coupling is done inside the module and is
thus not required on the host board.

SNR-SFP+LR-2 10Gbps
SFP+ LR 2km Transceiver
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 the
serial clock signal (SCL). The positive edge clocks data into those segments of the EEPROM that
are not written 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. 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 power monitoring, bias current monitoring, supply voltage monitoring and temperature
monitoring 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.
