Before one can begin to design a fiber optic cable plant, one needs to establish with the end user or network owner where the network will be built and what communications signals it will carry. Most contractors are more familiar with premises networks, where computer networks (LANs or local area networks) and security systems use structured cabling systems built around well-defined industry standards. Once the cabling exits a building, even for short links for example in a campus or metropolitan

for the cable runs, which may be installed by feeding pulling lines through the conduit with a fish tape, attaching the cable’s strength member to a pulling eye, and then pulling the cable through the conduit. Conduit may be run inside structures or underground, and in many cases conduits may already be in place for the other applications, such as power or telephone lines. When you are installing cable in conduits within a structure, be sure that you have allowed enough room for the cable or cables

Cable is the medium through which information usually moves from one network device to another. There are several types of cable which are commonly used with LANs. In some cases, a network will utilize only one type of cable, other networks will use a variety of cable types. The type of cable chosen for a network is related to the network's topology, protocol, and size. Understanding the characteristics of different types of cable and how they relate to other aspects of a network is necessary for

connection cable, unless the routers of choice are wireless. The most common choice of cabling is Ethernet Category 5e; the e is stands for enhanced speed. There are also several other types of cables to choose from. Fiber optics is currently the fast connection cable. This type of cable uses light to travel through glass and requires a higher level experience in dealing with and setting up. Cat 5(e) is the most common and is untwisted pair. Some may choose to use a coaxial cable which uses copper

certification exams, you have to know what cable type is appropriate for a given situation. It's also a good idea to know this for working in real-world production networks as well! After all, if we have the wrong cable, we don't have a network! This is particularly true of the following scenario, where we have: * A laptop connected to a switch (Cable 3) * Two switches connected to each other (Cable 2) * A PC connected to a switch (Cable 1) This is a very basic and common topology

When installing cables there are several factors to consider: cost, future expansion, bandwidth, signal strength, and EMI. Each type of cable has different specifications that affect these installations and every job will have different needs associated with those factors. When working on a worksite there are a few tools you will need; such as cable pulleys, punch downs, wire cutters, and cable strippers. You will need most of these tools to install your cable into your building. For preexisting

reduction of cable required and the efficiency of in using available communication circuit. Multipoint is also cheaper than point-to-point configurations. For Point-to-point configuration, the connection goes from one computer to another. Point to point is used when the computers generate enough data to fill the capacity of the communication circuit. Describe three types of guided media. The three types of guided media described herein are coax cable, fiber cable or twisted pair cable. There referred
