TX Fault is an open collector output, which should be pulled up with a 4.7k~10kΩ resistor on the host board toa voltage between 2.0V and Vcc+0.3V. Logic 0 indicates normal operation; logic 1 indicates a laser fault ofsome kind. In the low state, the output will be pulled to less than 0.8V.2. TX Disable is an input that is used to shut down the transmitter optical output. It is pulled up within the modulewith a 4.7k~10kΩ resistor. Its states are:Low (0~0.8V):Transmitter on(>0.8V,

SP-GB-ELX-CDFH6. These are the differential transmitter inputs. They are AC-coupled, differential lines with 100Ω differentialtermination inside the module.EEPROM InformationThe SFP MSA defines a 256-byte memory map in EEPROM describing the transceiver’s capabilities, standardinterfaces, manufacturer, and other information, which is accessible over a 2 wire serial interface at the 8-bitaddress 1010000X (A0h).
