Digital cable has characteristic impedance of 75 Ohm for unbalanced and 110 Ohm for balanced cables. Proper impedance matching is important because digital signal of high slew rate reflects on impedance boundaries causing jitter (noise in time domain). Digital cable is also constructed differently: it uses cheap copper, often silver plated, since signal at high frequencies travel only on the surface (skin effect). Shield is grounded on both ends and used as a return/GND - not very good for analog.
You could use analog cable as digital if you don't hear the difference caused by impedance mismatch (short cable, low slew rate from CDP, jitter rejecting DAC). If you use digital cable the optimum might be 1.5m (reflections timing). Coax will give you better performance than Toslink (fiberoptics) unless you have ground loops that Tosling breaks (being optical).
