I.      Absolute Maximum Ratings  

II.   Recommended Operating Conditions

III.           Optical Characteristics

Notes:  

1.       Class 1 Laser Safety per FDA/CDRH ａnd IEC-825-1 regulations.  

2.       Measured with a PRBS 2³¹-1 test pattern, @10.325Gb/s, BER<10^-12 .  

IV. Electrical Characteristics

Notes: 

1.       Connected directly to TX data input pins. AC coupled thereafter.  

2.       Or open circuit.

3.       Into 100 ohms differential termination.  

4.       These are unfiltered 20-80% values

5.       Loss Of Signal is LVTTL. Logic 0 indicates normal operation; logic 1 indicates no signal detected.  

6.       Receiver sensitivity is compliant with power supply sinusoidal modulation of 20 Hz to 1.5 MHz up to specified value applied through the recommended power supply filtering network.  

Notes:

1.       Circuit ground is internally isolated from chassis ground.

2.       T_FAULT is an open collector/drain output, which should be pulled up with a 4.7kΩ– 10 kΩ resistor on the host board if intended for use. Pull up voltage should be between 2.0V to Vcc + 0.3V.A high output indicates a transmitter fault caused by either the TX bias current or the TX output power exceeding the preset alarm thresholds. A low output indicates normal operation. In the low state, the output is pulled to <0.8V.

3.       Laser output disabled on T_DIS >2.0V or open, enabled on T_DIS <0.8V.

4.       Should be pulled up with 4.7kΩ- 10kΩ on host board to a voltage between 2.0V ａnd 3.6V. MOD_ABS pulls line low to indicate module is plugged in.

5.       Internally pulled down per SFF-8431 Rev 4.1.

6.       LOS is open collector output. It should be pulled up with 4.7kΩ – 10kΩ on host board to a voltage between 2.0V ａnd 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.

VI. Digital Diagnostic Functions

SFP+ -10G-850nm-MM-300m-DDM transceivers 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, SFP+ transceivers provide a unique 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). The digital diagnostic monitoring interface makes use of the 8 bit address 1010001X (A2h), so the originally defined serial ID memory map remains unchanged.
