Modern SFPs provide a standardized diagnostic monitoring
(SFF-8472) and/or laser
interface for optical transceivers.
The aim of this project is:
to create SFP I2C software libraries to access SFF-8472 and SFF-8690
in a standard way. See sub project
create a PC - GUI tool to make the SFPs monitoring information
easily accessible and enable easy access to user writeable
information. See SaFariPark.
create a hardware test-bed where four SFP+s can be exercised in
parallel. I.e. a 10 Gbps interface to each Tx/Rx pair (4x4 SMA) and
access to the four I2C interfaces via an I2C multiplexer, an FTDI
chip connected to USB
An effort is done to standardize the User-EEPROM space
for SFP modules as defined in SFF-8472.
