20 feet is the longest I know of
The standard for CAT5e is 100 metres
It depends on the length of th cable and the diameter of the copper cable used.
longest i have seen in a store was 100ft but if you need longer get a roll of Ethernet cable and 3 ends for it then make your own length of cable.
RS-232 standard is 50 feet.
About ten feet long
IEEE 1394b
The Cable Cat 6 is an Ethernet cable that supports fast Ethernet 10G BASE-T. This cable is available in a 20 meter length online from various retailers including cabling4less.
Scsi Cable (or more commonly know as the ribbon cable)

It looks like any other low voltage cable, such as a CAT-5 Internet cable. There are several variants to the RS-232 standard. The standard defines a 25 pin configuration for serial data communications. In many cases fewer conductors are used. Google RS-232 standard for definition of the connectors, cable length, restrictions, baud rates and voltage levels.
