- 20 – 80 % Measured with Module Compliance Test Board and OMA test pattern.
Digital Diagnostics Functions:
- GAOTek GAO-SFPPT-101 transceiver support the 2-wire serial communication protocol as defined in the SFP MSA1.
- Additionally, GAOTek SFP+ Transceivers provide a unique enhanced digital diagnostic monitoring interface which allows real-time access to device operating parameters such as transmitter optical power, receiver optical power, transceiver temperature, transceiver supply voltage and laser bias current. It defines an alarm system and warning flags, which alerts the end users when particular operating parameters are outside of a factory set normal range.
- Standard SFP+ Serial id provides access to identification information that describes the transceiver’s capabilities, standard interfaces, manufacturer and other information.
- 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 operating and diagnostics information is monitored and reported by a Digital Diagnostics Transceiver Controller (DDTC) inside the transceiver, which is accessed through a 2-wire serial interface. The memories are organized as a series of 8-bit data words that can be addressed individually or sequentially

Notes:
- Circuit ground is internally isolated from ground.
- TFault is an open collector or drain output.
- It should be pulled up with a 4.7k -10k ohms resistor on the host board if intended for use.
- Pull up voltage should be between 2.0V to Vcc +0.3V.
- High output indicates a transmitter fault caused by either the TX bias current or the TX output power exceeding the preset alarm thresholds.
- Low output indicates normal operation. In the low state output is pulled to <0.8V
- Laser output disabled when it is open or TDis > 2.0V, enabled on TDis < 0.8V.
- Should be pulled up with 4.7kΩ to 10kΩ on host board to a voltage between 2.0V and 3.6V.
- MOD_ABS pulls the line low to indicate the module is plugged in.
- Internally pull down per SFF-8431.
- Loss of signal is open collector output.
- This should be pulled up with 4.7 kΩ to 10 kΩ on host board to a voltage between 2.0V and 3.6V.
- Logic 0 indicates normal operation.
- Logic 1 indicates loss of signal.
