sfp-plus-i2c

Modern SFPs provide a standardized diagnostic monitoring (SFF-8472) and/or laser tunability (SFF-8690) 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 LIBSFP
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.

SaFariPark now open for public

May 29, 2017

SaFariPark is not a site to book holidays on the African plains - though with additional personal funding I am willing to add that feature. It is a software tool to read and write the digital interface of SFP/SFP+ transceiver modules. Together with a device to plug in multiple (4) SFP/SFP+ modules, creatively called MultiSFP (see Figure 1), it is a versatile tool for all your SFP needs. MultiSFP and SaFariPark have been developed by Nikhef as part of the ASTERICS program, and all is open hardware/open source.
