Notes:
1. TX Fault is an open collector output, which should be pulled up with a 4.7k~10k resistor on the host
board to a voltage between 2.0V and Vcc+0.3V. Logic 0 indicates normal operation; logic 1 indicates a
laser fault of some 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
module with a 4.7k~10k resistor. Its states are:
Low (0~0.8V):
Transmitter on
(>0.8V, <2.0V):
Undefined
High (2.0~3.465V):
Transmitter Disabled
Open:
Transmitter Disabled
3. MOD-DEF 0,1,2 are the module definition pins. They should be pulled up with a 4.7k~10k resistor on
the host board. The pull-up voltage shall be VccT or VccR.
MOD-DEF 0 is grounded by the module to indicate that the module is present
MOD-DEF 1 is the clock line of two wires serial interface for serial ID
MOD-DEF 2 is the data line of two wires serial interface for serial ID
4. LOS is an open collector output, which should be pulled up with a 4.7k~10k resistor on the host board to
a voltage between 2.0V and Vcc+0.3V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.
In the low state, the output will be pulled to less than 0.8V.
5. These are the differential receiver output. They are internally AC-coupled 100Ω differential lines which
should be terminated with 100Ω (differential) at the user SERDES.
6. These are the differential transmitter inputs. They are AC-coupled, differential lines with 100Ω
differential termination inside the module.
EEPROM Information
The SFP MSA defines a 256-byte memory map in EEPROM describing the transceiver’s capabilities,
standard interfaces, manufacturer, and other information, which is accessible over a 2 wire serial
interface at the 8-bit address 1010000X (A0h). The memory contents refer to Table 8.
