The front panel of the FMC will protrudes few cm out of the DIOT crate - this does not seem mechanically sound
To fit LC connectors, the front panel of the FMC needs to protrude out of the FMC, see below:
Working version is the blue holder (the metal is just temp solution), in the pictures it is tested with the System Board, not the Peripheral/Application board with which the FMC will be used, see the visualization of the Peripheral/Application board below.
This will work yet:
- it does not seem reliable and sound mechanically,
- it seems to require custom front panel for the DIOT application board,
- the fiber connections will be protruding out of the crate making it more prone to damage.
One solution would be to convert the FSI board into a DIOT form factor. Another to maybe use a different type of diode/connector - I have no good solution.
