It is said that coaxial has several advantages over ordinary TOSLINK
connections, a greater bandwidth being one of them.

Problem is, coax outputs are generally driver through a special lossy
transformer that rolls response off above about 12 MHz to reduce EMI.

IIRC, TOSLINK has barely 7 MHz of bandwidth.

It all depends on the current drive capabilties of the driver transsister
for the transmitter. There are now a number of transmitter parts. The design
of its driver is up to the equipment designer.
