I need a longer fiber optic cable

I remember seeing awhile back someone had posted a link to a place that sold the raw, solid core fiber optic cable. The current cables I have are too short to do what I want.

I purchased from them a while back. Quick and inexpensive

Not knowing about this I just bought fiber optic audio cables which were not expensive and available in length at least up to 5m.
