There is no real distance limitation between the headend and the distribution hub(s), it could theoretically be hundreds or thousands of miles. The cabling is all fibre, though in some special cases can be satellite. On modern networks your data connection gets split off at the CMTS anyway so the rest is primarily only used for TV these days.

Somewhat ambiguous/misleading or even incorrect I'm afraid.
Because being a "time based" slotted algorithm DOCSIS standard imposes an overall maximum "delay" limit of 0.8ms between
CableModem and
CMTS. As the velocity profiles/progation delays vary between Fibre and Coax and also the ratio between these may be different in the actual deployed HFC network then this for practical purposes limits the length to typically no more than 100 miles.
