Get an RME HDSPe MADI PCIe card and a format converter for fiber to coax. That will be your best solution.

PCIe Card: RME HDSPe MADI $1800
Converter: Lynx Technik OTR 1240 $366

That'll give you 128 channels i/o plus a stereo analogue output, 2in/2out MIDI ports, and word clock. You'll need a multimode LC to SC fibre to hook the converter in (the RME has SC connectors, the converter is LC connectors -- you can find these cables cheaply on amazon)

And avoiding those SSL Delta links is a good thing (ran them for years before there was MADI for Pro Tools directly from Avid) and they have issues. So you dodged a bullet.
