Overview
SFP Back2Back is an open-source printed circuit board by XDjackieXD, from the XDjackieXD/SFP-Back2Back repository on GitHub. It is a 2-layer board of 86 × 54 mm with 51 parts on 37 nets, routed with 495 tracks and 150 vias.
Its parts include 20 resistors, 10 capacitors, 4 diodes, 4 inductors and 3 connectors.
README
README.mdSFP+ Back2Back
This is a simple board to connect two SFP/SFP+ modules together.
So far it has only been tested with 10G fiber transceivers. While it should work with other 1G and 10G (and maybe even 25G) modules and DACs too, I have not tested it with those (and I know that DACs tend to be more of an issue with such passive adapters/extenders).

Questions
How big is the SFP Back2Back PCB?
It measures 86 × 54 mm and has 2 copper layers, 0.8 mm thick.
What parts does the SFP Back2Back use?
51 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the SFP Back2Back KiCad files?
From the XDjackieXD/SFP-Back2Back repository on GitHub, at the commit this page was made from: the board is sfp+_back2back.kicad_pcb and its schematic sfp+_back2back.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SFP Back2Back design in my own project?
Its repository states no licence, so its author keeps all rights: ask XDjackieXD before reusing the design.
