Performing a cable installation
When performing a cable installation, there are a lot of things that you have to put into consideration. First, you want to draw up a plan. Some things that you would want to include in the plan would be: where your telecommunications rooms are located, what is the distance from your leased line to your core router, and what type of cable are you going to be using for your backbone and horizontal lines. The first thing shouldn’t be cost when you are designing a network. You want to think of the safety and how your network will function with different mediums of cable. These things are important because your network has to meet the needs of the company. You also want to make sure you have things in place like what type of fire protection your network will have. You want to make sure your racks in your telecommunication rooms are grounded properly. Without these things your network will not be very safe. You want it to be useful but you don’t want to lose everything in a telecommunications room because you failed to plan ahead for accidents that can happen.
Once you have your plan intact and it has been approved you need to think about how you are going to get this cable in the building. What types of tools are you going to need? If you are going to run CAT 5e though out the building you will need several different tools; 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. There will be a few different tools you will need if you are putting cable into a preexisting building. You may then need a fish tape or fiberglass push pole. It really depends on the type of job you are going to be doing and what type of cable or fiber you are going to be working with. This will determine what tools you will need to get the job done correctly and safely.
If you are at a worksite and don’t have any wire strippers you could also use a razor blade knife to strip the jacket off the cable. It is something that will work if you don’t have any strippers handy. But of course this is not the most used method to strip cable. It will work if you need it right then.
All the things that I have talked about are important because it will help you to make sure you have a plan that covers everything. You not only need to think about cost but safety as well. Make sure you have the right tools for the right job. Also make sure your measurements are correct cause this could also make or break your network plan.
Wall plate – it is the plastic or metal plate that screws into the wall. It has some sort of connector, usually coax, rj11, rj45, duplex receptacle, or fiber optic. This is where the device plugs into the wall.
Connector – a device that joins two pieces of cabling
Crossover cable – A crossover cable is a type of twisted pair copper wire cable for LANs (local area network) in which the wires on the cable are crossed over so that the receive signal pins on the RJ-45 connector on one end are connected to the transmit signal pins on the RJ-45 connector on the other end. NIC – A network interface controller (NIC, also known as a network interface card, network adapter, LAN adapter, and by similar terms) is a computer hardware component that connects a computer to a computer network HUB – An Ethernet hub, active hub, network hub, repeater hub, multiport repeater or hub is a device for connecting multiple Ethernet devices together and making them act as a single network segment. Bridge – A device used to connect two separate Ethernet networks into one extended Ethernet. Bridges only forward packets between networks that are destined for the other network.
Term used by Novell to denote a computer that accepts packets at the network layer and forward them to another network Switch – A switch is a multi-port network bridge that processes and forwards data at the data link layer (layer 2) of the OSI model. Some switches have additional features, including the ability to route packets. These switches are commonly known as layer-3 or multilayer switches. Router – A router is a networking device that forwards data packets between computer networks, commonly specialized hardware. This creates an overlay internetwork, as a router is connected to two or more data lines from different networks.
Infrared (IR) – Infrared (IR) is a wireless mobile technology used for device communication over short ranges. Radio Frequency – RF is any frequency within the electromagnetic spectrum associated with radio wave propagation. When an RF current is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space. Many wireless technologies are based on RF field propagation. Microwave – A series of microwave repeaters, spaced up to 50 miles (80 kilometers) apart, which relay messages over long distances using highly directional microwave beams.
