V. Digital Diagnostic Functions
Finisar’s EPON Stick supports the 2-wire serial communication protocol as defined in the
SFP MSA
2
.
Additionally, Finisar’s EPON Stick (SFP-ONU) provides a unique enhanced digital
diagnostic monitoring interface which allows real-time access to a device’s 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 alarms and warning flags which alerts end-users when certain 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), A0h stores static
information including product and vendor IDs while A2h contains real-time diagnostic
data.
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. When the serial protocol is activated, the serial clock
signal (SCL) is generated by the host. The positive edge clocks data into the SFP
transceiver into segments of the EEPROM that are not write-protected. The negative
edge clocks data from the SFP transceiver. The serial data signal (SDA) is bi-directional
for serial data transfer. The host uses SDA in conjunction with SCL to mark the start and
end of serial protocol activation. The memories are organized as a series of 8-bit data
words that can be addressed individually or sequentially.
For more information, please contact Finisar.
Digital diagnostics for the EPON Stick (SFP-ONU) are internally calibrated by default.

PIN Notes:
1. TX Fault is an open collector/drain output, which should be pulled up with a 4.7K–
10KΩ resistor on the host board. Pull up voltage between 2.0V and VccT, R+0.3V.
When high, output indicates a laser fault of some kind. Low indicates normal
operation. In the low state, the output will be pulled to < 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 4.7–10 KΩ resistor. Its states are:
Low (0 – 0.8V): Transmitter on
(>0.8, < 2.0V): Undefined
High (2.0 – 3.465V): Transmitter Disabled
Open: Transmitter Disabled.
3. Mod-Def 0,1,2. These are the module definition pins. They should be pulled up with a
4.7K – 10KΩ 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 wire serial interface for serial ID
Mod-Def 2 is the data line of two wire serial interface for serial ID.
4. LOS (Loss of Signal) is an open collector/drain output, which should be pulled up
with a 4.7K – 10KΩ resistor. Pull up voltage between 2.0V and VccT, R+0.3V. When
high, this output indicates the received optical power is below the worst-case receiver
sensitivity (as defined by the standard in use). Low indicates normal operation. In the
low state, the output will be pulled to < 0.8V.
5. VeeR and VeeT may be internally connected within the SFP module.

6. RD-/+: These are the differential receiver outputs. They are AC coupled 100Ω
differential lines which should be terminated with 100Ω (differential) at the user
SERDES. The AC coupling is done inside the module and is thus not required on the
host board.
7. VccR and VccT are the receiver and transmitter power supplies. They are defined as
3.3V ±5% at the SFP connector pin. Inductors with DC resistance of less than 0.5Ω
should be used in order to maintain the required voltage at the SFP input pin with
3.3V supply voltage. VccR and VccT may be internally connected within the SFP
transceiver module.
8. TD-/+: These are the differential transmitter inputs. They are AC-coupled, differential
lines with 100Ω differential termination inside the module. The AC coupling is done
inside the module and is thus not required on the host board.
