Number of fibres in a fibre optic cable
Number of fibres in a fibre optic cable
(OP)
I have seen that there are various amounts of fibres 8,12,24 etc in fibre optic cables. Is this just one signal per fibre. So for instance an 8 fibre cable could take 8 separate signals?
Thanks
Thanks

You must first define 'signal', then you can count them.
If you mean optical wavelength, most are single wavelength. But higher value cables (e.g. oceanic) might have multiple wavelengths.
Once you past that, it's multiple signals all the way down. Look up the ISO 7-Layer Model to grasp the typical layering concept.
The fiber that reaches my house is single wavelength. Each fiber is passively connected to as many as 16 houses. They use TDMA to share.
The cable itself along the road seems to contain 12 fibers, but this would vary. So a tiny one-quarter inch diameter cable can feed 192 houses.

One cannot completely avoid copper wire. Cameras obviously need power. Thus the rising popularity of Ethernet with POE.
