The Cat 5e and Cat 6 ethernet cables are available in 50 foot and longer lengths and have no problem working that distance. For a longer distance I would use the Cat 6 just because it is of higher quality and can use the same ports. I really don't know how far they work only that they will work if you purchase a non custom cable length and have seen a length as long as 250 feet for the CAT 6 cables

There are primary two different systems. If it is cable then RG6 cable is used. If it is a LAN then Cat. 5 will be used.
It's short for "category five", which is a type of cabling. The "Cat 5" part refers to the technical specifications of the cable, such as the bandwidth. Cat 5 cable is (usually) unshielded twisted-pair.
Cat 5 is a type or standard of ethernet cable (350 Mhz) and is not as good as the Cat 6 (500+Mhz) which will work wherever you were going to use the Cat 5 ethernet cable and not require replacement as cable/DSL broadband internet speeds increase
Either a Cat 5 or Cat 6 ethernet cable will fit the PS3 ethernet outlet. You must also have something to plug the cable into that is connected to the internet, for instance a router or modem.
A Cat 5(good) or Cat 6 (better) ethernet cable plugs into the router and the ethernet slot in the back of the PS3 for a wired internet connection.
The ethernet cable needs to be connected to a router or modem and it works fine although I chose to purchase the CAT 6 ethernet cable. The speed test for the internet connection is faster with the ethernet connection than with the WiFi connection and I have never lost a connection like I did with WiFi
The back of the PS3 has a spot for an Ethernet cable to allow wired connection with the internet. Purchase a Cat 5 or Cat 6 ethernet cable long enough to go for the back of the PS3 to the source of your internet connection. Ebay had Cat 6 50 foot cables for under 20$ including S/H.
ADSL (asymmetrical digital subscriber line) is a protocol that you ISP (internet service provider) use it is a analogue signal. cable normally is a cat 5e or cat 6 in to the modem and is a digital connection (much faster)
VGA cable
You can tell the CAT level (or category) of a cable by looking for imprinted markings along the length of the cable. Look for the number preceded by 'CAT.' That is the category of the cable.
There is the USB cable and the twisted pair cable (Cat 5 and Cat 6) for networking.
