This is a pair of Gefen blocks that make up a DVI extender.
It was used as a link between a media player and a remote projector.
I don't have the fibre optic cable to test it end to end.
The units power up, but that's it, no further testing.

As I'm decluttering selling with no warranty refunds or returns.
Just the modules, nothing else.
Post is UPS next day, but collection welcome.

Any questions?
