The glass fiber requires more protection within an outer cable than copper. For these reasons and because the installation of any new wiring is labor-intensive, few communities yet have fiber optic wires or cables from the phone company&#8217;s branch office to local customers (local loop).<br \/>\nIn telephony, a local loop is the wired connection from a telephone company&#8217;s central office in a locality to its customers&#8217; telephones at homes and businesses. This connection is usually on a pair of copper wires called twisted pair. The system was originally designed for voice transmission only using analog transmission technology on a single voice channel. Today, your computer&#8217;s modem makes the conversion between analog signals and digital signals. With Integrated Services Digital Network (ISDN) or Digital Subscriber Line (DSL), the local loop can carry digital signals directly and at a much higher bandwidth than they do for voice only.<br \/>\nLocal Loop diagram<br \/>\n<img decoding=\"async\" loading=\"lazy\" class=\"alignnone size-full\" src=\"https:\/\/exampracticetests.com\/ISC\/SSCP\/wp-content\/uploads\/exam\/__Page_441_Image_0001.jpg\" \/><br \/>\nImage from: <a href=\"http:\/\/www.thenetworkencyclopedia.com\/entry\/local-loop\/\" title=\"External link\" rel=\"nofollow noopener\" target=\"_blank\">http:\/\/www.thenetworkencyclopedia.com\/entry\/local-loop\/<\/a><br \/>\nThe following are incorrect answers:<br \/>\nNew loop This is only a detractor and does not exist<br \/>\nLoopback In telephone systems, a loopback is a test signal sent to a network destination that is returned as received to the originator.
