Product Description
DWDM-SFP10G-80-C31-T02 Enhanced Small Form Factor Pluggable SFP+ transceivers are designed
for use in 10-Gigabit Ethernet links up to 80km over Single-Mode fiber. They are compliant with SFF- 8431,
SFF-8432 and ITU-T G.698.1. The transceiver designs are optimized for high performance and cost
effective to supply customers the best solutions for telecommunication.
This transceiver consists of two sections: The transmitter section incorporates a cooled EML laser. And the
receiver section consists of a APD photodiode integrated with a TIA. All modules satisfy class I laser safety
requirements. Digital diagnostics functions are available via a 2-wire serial interface, as specified in
SFF-8472, which allows real-time access to device operating parameters such as transceiver temperature,
laser bias current, transmitted optical power, received optical power and transceiver supply voltage.

4. Mod_ABS is connected to VeeT or VeeR in the SFP+ module. The host may pull this contact up to
Vcc_Host with a resistor in the range 4.7 kΩ to10 kΩ.Mod_ABS is asserted “High” when the SFP+
module is physically absent from a host slot.

Serial Interface for ID and Digital Diagnostic Monitor
DWDM-SFP10G-80-C31-T02 transceiver support the 2-wire serial communication protocol as defined in
the SFP+ MSA. The standard SFP+ serial ID provides access to identification information that describes
the transceiver’s capabilities, standard interfaces, manufacturer, and other information. Additionally, This
SFP+ transceivers provide an enhanced digital diagnostic monitoring interface, which allows real-time
access to device operating parameters such as transceiver temperature, laser bias current, transmitted
optical power, received optical power and transceiver supply voltage. It also defines a sophisticated
system of alarm and warning flags, which alerts end-users when particular operating parameters are
outside of a factory set normal range.
The SFP MSA defines a 256-byte memory map in EEPROM that is accessible over a 2-wire serial
interface at the 8 bit address 1010000X(A0h), so the originally monitoring interface makes use of the 8 bit
address(A2h), so the originally defined serial ID memory map remains unchanged. The structure of the
memory map is shown in Table1.

Typical Interface Circuit
Recommended power supply filter
Note:
Inductors with DC resistance of less than 1Ω 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 30 mA greater
than the steady state value

Tel: +86-773-3116006 info@glsun.com Web: www.glsun.com - 2 - Product Description DWDM-SFP10G-80-C31-T02 Enhanced Small Form Factor Pluggable SFP+ transceivers are designed for use in 10-Gigabit Ethernet links up to 80km over Single-Mode fiber. They are compliant with SFF- 8431, SFF-8432 and ITU-T G.698.1. The transceiver designs are optimized for high performance and cost effective to supply customers the best solutions for telecommunication. This transceiver consists of two sections: The transmitter section incorporates a cooled EML laser. And the receiver section consists of a APD photodiode integrated with a TIA. All modules satisfy class I laser safety requirements. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-8472, which allows real-time access to device operating parameters such as transceiver temperature, laser bias current, transmitted optical power, received optical power and transceiver supply voltage. Product Feature Supports 9.95 to 11.3 Gb/s bit rates Duplex LC connector Hot pluggable SFP+ footprint Cooled EML transmitter and APD receiver Applicable for 80km SMF connection Low power consumption, < 1.5W 100 GHz channel spacing Digital Diagnostic Monitor Interface Optical interface compliant to ITU-T 694.1& G.698.1 Electrical interface compliant to SFF-8431& SFF-8432 Operating case temperature: 0 to 70 °C (commercial) Application 10G Ethernet 2x,4x, 8x Fiber Channel ITU-T G.698.1 Other optical links Product Channel Selection Channel# Product Part No. Frequency (THz) Center Wavelength (nm) 17 SFP-10G-DWDM-C17-80 191.7 1563.86 18 SFP-10G-DWDM-C18-80 191.8 1563.05

Should be pulled up with 4.7k – 10k ohms on host board to a voltage between 3.15V and 3.6V. 3. Tx_Disable is an input contact with a 4.7 kΩ to 10 kΩ pullup to VccT inside the module. 4. Mod_ABS is connected to VeeT or VeeR in the SFP+ module. The host may pull this contact up to Vcc_Host with a resistor in the range 4.7 kΩ to10 kΩ.Mod_ABS is asserted “High” when the SFP+ module is physically absent from a host slot.

Tel: +86-773-3116006 info@glsun.com Web: www.glsun.com - 8 - Serial Interface for ID and Digital Diagnostic Monitor DWDM-SFP10G-80-C31-T02 transceiver support the 2-wire serial communication protocol as defined in the SFP+ MSA. The standard SFP+ serial ID provides access to identification information that describes the transceiver’s capabilities, standard interfaces, manufacturer, and other information. Additionally, This SFP+ transceivers provide an enhanced digital diagnostic monitoring interface, which allows real-time access to device operating parameters such as transceiver temperature, laser bias current, transmitted optical power, received optical power and transceiver supply voltage. It also defines a sophisticated system of alarm and warning flags, which alerts end-users when particular operating parameters are outside of a factory set normal range. The SFP MSA defines a 256-byte memory map in EEPROM that is accessible over a 2-wire serial interface at the 8 bit address 1010000X(A0h), so the originally monitoring interface makes use of the 8 bit address(A2h), so the originally defined serial ID memory map remains unchanged. The structure of the memory map is shown in Table1. Table 1. Digital Diagnostic Memory Map (Specific Data Field Descriptions) Digital Diagnostic Specifications DWDM-SFP10G-80-C31-T02 transceivers can be used in host systems that require either internally or externally calibrated digital diagnostics.

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 30 mA greater than the steady state value
