as far as I know it is a 30ft DVI and a 30 ft SCSI cable, not optical.

No it is a 30 METER optical cable. He even gives the exact model number. It is fiber with a powered adapter on each end. Works great but not cheap. Where'd you get SCSI from. Every funny lookin connector is SCSI? It is a DVI connector and an MDR20 connector. MDR20 is actually somewhat common for digital video. In this case though it is used for signaling.

Depending on the type of fiber, you have a couple of options to "repair" it instead of replacing. We have not used these cables so I don't have a clue if this is really possible, but all of these methods have been used by us in the past for FOC.

1) find a local OSP, or Commercial Cabling Co that does fusion splicing & have them repair it w/ a fusion splice. This would be the best method as it will add <1db loss if done correctly.

2) Use a installer friendly splice like a Siecor Unicam or a 3M FiberLok. If you are not sure about doing this yourself, contact a local commercial cabling company. This will repair it, but the loss through the splice will >1db.

3) Find a local network cable assembly house & have them make you one. May be possible if they can get the type (SM/MM, size, etc.) & parts. No loss, as it is a new cable.

Used to splice fiber in a previous "worklife".
Hope this helps.
