I was told for long runs always go optical, as coax picks up interference.
Coax only good for short connections.
Also, as it is pulses of light, on and off, it either works fully or not at
all,so no degregation of sound.

Can several digital optical leads be linked together with no loss in
quality?

You mean to make a longer cable?

Not recommended. However there are such things as optical repeaters such
as
the one shown at
http://www.connecttech.net/product_i...oducts_id/1096 .

With optical leads, can they be any length without effecting quality?

No, their length is usually considered to be limited by their relatively
high optical losses and the limited sensitivity and power of the optical
receivers and transmitters.

Usual length limit is about 30 feet without a repeater.

Conventional wisdom is that if you want a long digital run, use coax. If
your equipment has only optical inputs and outputs, there are
optical-to-coax converters for reasonable prices.
