Cables to connect the lightpipe-only A/D option are, of course, standard lightpipe cables which can be purchased from any pro audio retailer. Hence Focusrite do not offer an Focusrite lightpipe cable option.

Cables to connect the 9-pin connector for AES and S/PDIF use are available separately from Focusrite as follows:

S/PDIF: 9-pin male connector to 4x phono (RCA) female connector cable.
UK MSRP £25 excl. VAT

AES-EBU: 9-pin male connector to 4 x XLR male connector cable.
UK MSRP £25 excl. VAT

Note that these cables are NOT included in the price of the A/D options, since different formats require different cables.
