By fios, this would be the Verizon fiber-optic service? And, the cable in question is from the set top box to a monitor? Assuming that the answer is yes to both, then a video cable from the set top box should be one with a characteristic impedance of 75ohms. RG58 is a 50ohm cable, so avoid that one. For most short runs of a few feet, then RG6 or almost any other 75ohm co-ax will do the job. For long runs, in excess of 50 feet or so, then the quality of cable can become important to the signal quality received at the television, so a bit more research might be worthwhile. However, there is rarely a "right" or a "wrong" cable to be using as long as it is a 75ohm co-ax.
The type coax you need depends on the type service you have. For satellite service, we use a higher rated coax cable (RG6) to allow for a higher frequency for channels and back feeding capability. RG59 is a lower rated cable.
Depends on the coax type - thinnet coax is 185 meters per segment, thicknet is 500 meters

It could be star or bus, but historically, coax cable was used in bus architecture.
You can use it for Ring and Bus.
The S-Video connector and cable will give you a better picture than coax or a RCA type pin video connector and cable will.
fiber-optic cabling it is. usually coax 'f' connector
In northAmerica all coaxial connections made to a television are made with 75 Ohm coax. Typical sizes will be RG-59, RG-6 or maybe RG-11 (less common).
Look for cables with the most shielding. The shielding in coaxial cable can be from a little to almost 100 percent. The better cables will have the most shielding.

It depends on the quality of the cable (how much copper it has) and the gauge of the wire. The most common type of gauge is 18 AWG. Also, the weight depends on the type of packaging - wooden spools are the most common. An 1000' spool of 18 AWG coax on a wooden spool weighs 38.6 pounds.
