1. Horizontal Cable : A type of inside cable designed for horizontal use in non-plenum areas. While horizontal cable must be fire retardant, the National Electrical Code (NEC) specifications are not as demanding as those governing the use of plenum cable or riser cable. See also NEC, plenum, plenum cable, and riser cable.
2. Backbone Cable : Backbone cabling is the inter-building and intra-building cable connections in structured cabling between entrance facilities, equipment rooms and telecommunications closets. Backbone cabling consists of the transmission media, main and intermediate cross-connects and terminations at these locations. This system is mostly used in data centers.
3. Patch Note 2: A cable having optical fiber(s) , plus a metallic strength member or armor, does not qualify as a composite cable. Hybrid •An optical communications cable having two or more different types of optical fibers, e.g., single-mode and multimode fibers.
15. Pulling Cable : The act of pulling the wires, as of a puppet; hence, secret influence or management, especially in politics; intrigue
16. Wavelengths of Light: The length of a single cycle of a wave, usually measured from crest-to-crest. For electromagnetic waves
17. EMI : is the disruption of operation of an electronic device when it is in the vicinity of an electromagnetic field (EM field) in the radio frequency (RF) spectrum that is caused by another electronic device.
18. Optical-Fiber Strand : Is this referring to the actual pure glass on the middle of the fiber
19. Index of Refraction : the ratio of the velocity of light in a vacuum to that in a medium. 20. wordnetweb.princeton.edu/perl/webwn
21. Cable Jacket : The outer protective coating which covers the core of the cable..
22. Cladding Size : A metal coating bonded onto another metal under high pressure and temperature.
23. Multifiber Cables : Fiber optic Cable bearing many fibers independently sheathed and capable of carrying unrelated signals. They often surround a central strength member, and can be either loose- or tight-buffered. One standard configuration is a 12-fiber cable.
Unit 5 assignment 1 and definitions 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…
As activity on both of the above projects escalate in 2013, there will be significant costs incurred which are directly related to the projects but not directly connected to the day to day activities of the business. Hence we will wish to collect these costs separately so that they do not detract from the normal trading results. Costs incurred will be both of capital and revenue (P&L) expenditure in nature. In due course CPAs will be raised for both projects against which we will record the costs…
Glen Gorman Jr. NT1310 July 23, 2013 Unit 2 Triple Play Marketing With the ever increasing development in technology and the cut throat competition to be the number one Internet/Television provider in the nation. Lightspeedtelecom has set the bar as the leader in Multiple Systems Operations. There establishments located in all 50 states is one of the reasons Lightspeedtelecom is on top of the totem pole. Going into details on how Lightspeedtelecom has achieved this status will take a life…
Colton Young NT1310 Brian Meyer 7-27-15 Forum 3.1 To transmit light effectively, fiber optic cable must contain glass of the highest purity. The process of making glass with this level of purity is very demanding, requiring careful control over the materials and processes involved. Step #1 Create the Fiber Optic Preform A preform is a cylindrical glass blank that provides the source material from which the glass fiber will be drawn in a single, continuous strand. Creating the preform takes several…
Assessment: Week 1 Mrs. Goodbrake, NT1310 3/18/2014 1.) A: Local Loop is simply a loop of copper wire that travels on a cable pair known as twisted pairs. Those pairs allows current to flow from the telephone to the central office and back this system was originally designed for voice transmission only using analog transmission technology on a single voice channel. B: The Central Office serves a group of customers in a local area in which the customers are identified by the…
