The ADAT optical digital interface is common on many digital audio systems, even if it is less well-used than perhaps it deserves to be. Each optical port allows up to eight channels of data to be transferred via a simple, low-cost light-pipe, making it ideal for carrying multiple channels between pieces of digital audio equipment - such as connecting an external set of mic pres like the Clarett OctoPre to a computer audio interface. Most of the larger (and some of the smaller) Focusrite interfaces include ADAT input or I/O and as a result it's easy to expand the number of inputs (and often outputs) available to your interface using this method.
