Premises Equipment
Finisar’s EPON Sticks are combination of a SFP transceiver with a built-in EPON ONU.
They comply with IEEE802.3ah EPON standard and optionally, CTC OAM
specifications, or DPoE
TM
specifications. Digital diagnostics functions are available via
the 2-wire serial bus specified in the SFP MSA.
Note 1: Compliant with IEEE Std 802.3ah-2005 with one exception on RMS spectral width which is less
than 4.0nm for PX10 modules including FTEN2x15P1NUN and FTEN2x15P1NUN-BC.

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.
