Because unshielded twisted pair cable can provide you good performance than coaxial
Posted by HamidAliKhan
Friends! Coaxial cable is fine for networking. However, unshielded twisted pair wire - the type used by the 10BASE-T Ethernet specification - deserves serious consideration. First, a twisted pair-wired network is much more reliable because of the physical star topology. Problems are a lot more common on coaxial networks, and they're much more difficult to troubleshoot. That can mean the difference between a whole network being inoperable for several hours versus one person being down for a few short minutes.
Second, unshielded twisted pair is plentiful and readily available. Unshielded twisted pair cabling typically consists of four pairs of wires wrapped in a common sheath. The phone system only uses two of those pairs, leaving two extra pairs for transmitting and receiving data. You simply tap into the telephone system at the punch down block in the wiring closet and at the office, cube or other work location. It's that simple.
Third, unshielded twisted pair cabling is inexpensive and therefore cost-effective. And it's easy to work with - much easier than thick, unwieldy coaxial cabling. It doesn't take much effort to install or prepare, so why not go with a simple, inexpensive, plug-and-play unshielded twisted pair solution? Thanks.
