It's project time again!!!
For a future project, I need to conveniently probe an SFP transceiver while it's operating. Not having found an SFP extender that suited my needs, I made my own based on an HDMI cable.
The SFP end on the top goes into a 3D-printed shell.
The receptacle board fans out all low-speed signals to headers for convenient probing and interception. It can be cut at the white line to get access to the bottom side of the SFP.
1GE link works, 10GE is to be tested.
