Cables

The more common MADI cable uses the larger SC connector, and is a 2x-SC-to-2x-SC, 62.5/125 µm, multimode cable. Newer cables use the smaller LC connector. The multi-mode cable enables transmission up to 3km.

It is also possible to use single-mode cables for distances up to 40k, but these require explicit support by the transmitters and receivers.
