So no optical connector expected?

SCSI connectors can be electrical connectors or optical connectors.

Light Peak connector Intel showed off a new optical connector at its developer forum that it believes could replace the rat's nest of cables behind your computer.

Many types of optical connector have been developed at different times, and for different purposes.

A multi-fiber optical connector is designed to simultaneously join multiple optical fibers together, with each optical fiber being joined to only one other optical fiber.

Multi-fiber optical connectors are designed to be used wherever quick and/or repetitive connects and disconnects of a group of fibers are needed.

The multi-fiber optical connector can be used in the creation of a low-cost switch for use in fiber optical testing.

I guess that means that USB is an optical connector too?

If they transfer to metal-optic active cabels: you'll have to buy new ones, if they transfer to internally optical connectors: you'll have to buy new ones.

A fiber pigtail is a single, short, usually unbuffered, optical fiber that has an optical connector pre-installed on one end and a length of exposed fiber at the other end.
