The straight-through wired cat5e patch cable is used to connect computers, printers and other network client devices to the router switch or hub (the host device in this instance).
The first major difference is the gigabit standards require the use of all four pairs (all eight wires), unlike Fast Ethernet which only utilizes two pairs of wires. As a result, in Gigabit Ethernet, all four pairs must be crossed when building a Crossover cable. That said, Gigabit Ethernet requires Auto MDI-X.
Gigabit ethernet (or 10/100/1000 Mbps) gets all its super-charged data power from using all four pairs, or all eight wires, when transferring the full 1000 Mbps of data from one computer to another.
The 4 stranded cable isn't capable of gigabit ethernet (no surprise there). In fact, it can't even do fast ethernet.
Cat 5e is currently the most commonly used cable, mainly due to its low production cost and support for speeds faster than Cat 5 cables. The Cat 6 Ethernet cable supports higher bandwidths than Cat 5 and Cat 5e cables.
Grey-colored cables typically represent standard ethernet connections, while green cables represent crossover ethernet connections. Yellow cables are used to signify POE (power over ethernet), while blue cables are used for terminal server connections.
The word “RxDx” is coined by binding two terms, Rx, the symbol of prescription, and Dx, the medical abbreviation of diagnosis.
Modern fiber optic cables can carry a signal quite a distance -- perhaps 60 miles (100 km). On a long distance line, there is an equipment hut every 40 to 60 miles.
The TX (sometimes referred as "T" only) means it's a CAT5 UTP straight through cable using two of the four available pairs and supports speeds up to 100 Mb. Maximum length is 100 meters and minimum length between nodes is 2.5 meters.
Fiber optic cable jacket colors can make it fast and simple to recognize exactly which type of cable you are dealing with. For example, the color yellow clearly identifies a single mode cable, while orange indicates multimode.fiber patch cord
