Hi Experts

Could you point how to check if an internet modem/ instalation is using Optical Fiber in oposition to a coaxial cable?

I means in hardware characteristics and speeds.

Thanks in advance

optical cable is more immune to electromagnetic noise and has the capability of a higher bandwidth than cable. In my docsis modem I am using 12 channels for download and 3 for upload. Fibre would only be one channel up and one down.

With cable as the speeds go up the more channels are required as each channel has a fixed amount of bandwidth.  enabling/disabling channels is one way of the isp to limit your speeds

Ok.

But at this time I need the phisical - visual - characteristics of each one to be sure I'm receiving the correct devices.... to have the correct contracted services.

A site diagnosys to evidence what kind of connection is running also... if possible.

just look at the connection.. cable and fibre are totally different. one uses RG59 cable and the other uses fibre optic cable   (there will be 2 cables for fiber optic one for send and one for recieve)
