Cat-5e/Cat-6 have a maximum distance of 100m or about 325 ft. IF you need to go that far, you need to think of fiber or using repeaters.

CimmerianX and nuwan4u are mostly correct. There are a number of factors that limit the length of a single ethernet link, and the default max (IEEE standards) for a cat-5 to cat-7 cable is 100 meters. The main issue is not only signal attenuation at distances beyond that, but the amount of time the signal requires to traverse the distance. You might get longer distances by using specialized end-point electronics (balanced line drivers with cat-7 cable may get you 150 meters). In any case, if you have to go beyond 100M, you are advised to use optical connections and cable. Honestly, optical cables and hardware will probably be more cost-effective these days than cat-6 cables w/ line drivers + the required repeaters. IE, get a switch at each end that has a fiber-optic connection for switch-to-switch connectivity, and the requisite fiber cable. These days, a fiber cable will probably be cheaper than a copper twisted-pair trunk.

Cat6 cable is perfect for supporting 10 Gigabit Ethernet. Since technology and values are continuously evolving, Cat 6 is the wisest choice of cable when taking any possible future updates to your network into consideration.
