...the art by making it a fiber optic network. This paper will include what hardware will be necessary for the inside of the building and outside of the building and how we would expand the fiber to an adjacent building if it is built. This paper will also describe the safety procedures that will be followed during the fiber installation. INSTALLATION HARDWARE PULLING EYE- When running a cable through a wall, conduit or other inaccessible space a pulling eye can be an indispensable tool. This device is specially designed to attach to the strength member of the cable at one end and a pulling line on the other. The pulling line is used to pull the eye with the attached cable through an inaccessible space. This allows you to pull the cable and protect the fiber ends from damage. PULL BOX – A pull box is usually installed after a long straight run or every time the set of turns totals 180 degrees or more. The pull box is used to create a intermediate opening for the pulling cable to reduce the length of cable being pulled through the conduit or to reduce the number of turns the cable is being pulled through at a given time. It is important to keep in mind the bend radius of the cable when using a pull box. SPLICE ENCLOSURES – Splice enclosures can take many forms depending on their location and application. Splice enclosures can be typically place in one of the two following categories. 1. Radial Splice Enclosures – radial splice enclosures have cables enter and exit the enclosure...

...Unit 4 Assignment 1 Copper vs. Fiber Pape The two most common and widely used cabling types today for the means of communication all over the world are copper and fiber. They both do the same thing, transmit information from point A to point B but both have their strengths and weaknesses and therefore, a person installing cabling may be reluctant to choose one over the other. Copper cabling is less expensive to install. Copper wiring is flexible when installing so incase a technician has to bend it around a wall or at a certain angle to reach it to an end point, the cable can handle it. Also equipment to support copper wiring is relatively inexpensive to run. The weaknesses to copper wiring would be that it is susceptible to electromagnetic inference (EMI) from outside forces and also has a higher rate of corrosion over time by oxidation. Fiber optic cabling is a more expensive option for communications. Fiber optic cabling is immune to EMI and other noise interferences and therefore the chance of signal loss is greatly reduced. One drawback on this type of cabling is that just like its copper; fiber optic cabling is very durable and tough making it harder to work with when it comes to installing it. A technician will have to be very well trained in handling it to get the most out of it for the customer. But fiber optic cabling has a much higher bandwidth over copper so it can handle much more traffic as well as at higher speeds than copper wiring. In the real world, one...

...NT 1310T 22 February, 2014 CABLES Twisted Pair cable Twisted pair is the ordinary copper wire that connects home and many business computers to the telephone company. To reduce crosstalk or electromagnetic induction between pairs of wires, two insulated copper wires are twisted around each other. Each connection on twisted pair requires both wires. Since some telephone sets or desktop locations require multiple connections, twisted pair is sometimes installed in two or more pairs, all within a single cable. For some business locations, twisted pair is enclosed in a shield that functions as a ground. This is known as shielded twisted pair (STP). Ordinary wire to the home is unshielded twisted pair (UTP). Twisted pair is now frequently installed with two pairs to the home, with the extra pair making it possible for you to add another line (perhaps for modem use) when you need it. Twisted pair comes with each pair uniquely color-coded when it is packaged in multiple pairs. Different uses such as analog, digital, and Ethernet require different pair multiples. Although twisted pair is often associated with home use, a higher grade of twisted pair is often used for horizontal wiring in LAN installations because it is less expensive than coaxial cable. The wire you buy at a local hardware store for extensions from your phone or computer modem to a wall jack is not twisted pair. It is a side-by-side wire known as silver satin. The wall jack can have as many five kinds of...

...Joel Anderson Equiptment and cables found in a standard equiptment room The backbone cabling can be either UTP or fiber optics. In larger networks today, fiber is most often used for its longer distance capability and higher bandwidth. TIA 568 specifies two multimode fibers, 62.5/125 (OM1) - the most common MM fiber until network speeds exceeded 1 Gb/s, and 50/125 (OM2 or OM3 - laser optimized) - a higher bandwidth fiber compatible with all fiber equipment. OM3 50/125 fiber is rated for use with lasers for >gigabit networks and is more often the choice now. Singlemode fiber is also specified for longer backbone links, as in a campus, for very high speed networks or where distance exceeds even OM3 fiber capability. Horizontal connections have traditionally been UTP copper, compatible the network port provideded on practically every type of computer gear. With the advent of wireless communications of adequate bandwidth and the inclusion of wireless adapters in all laptops and many other portable devices, wireless has become the user connection of choice. Virtually every corporate network now includes wireless, which is, of course, not wireless, since access points are connected into the network with copper or fiber cabling. Provision is necessary in the design of a facility for adequate numbers of access points, cabling to the access points and proper power, also conditioned and uninterruptible. Fiber optics is also a horizontal option in TIA 568...
