A trust is a relationship established between domains that enable users in one domain to
Todays fiber-optic communication systems use semiconductor devices such as light-emitting
diodes (LEDs) and laser diodes. The difference between LEDs and laser diodes is that LEDs
produce incoherent light, while laser diodes produce coherent light. For us
A continuity tester is an item of electrical test equipment used to determine if an electrical
path can be established between two points; that is if an electrical circuit can be made. The
circuit under test is completely de-energized prior to connecting
Incoherent light- Light in which the electric and magnetic fields of photons are completely
random in orientation. Incoherent light is typically emitted from light bulbs and LEDs.
Laser- Acronym for light amplification by stimulated emission of radiation.
Conduit is pipe. It can be metallic, nonmetallic, flexible, or rigid(depending upon local codes)
and runs from a work area to a telecommunications room to the equipment room. One
advantage of using conduit to hold the cables is that conduit may already ex
Transmission errors are common in communication systems due to different
reasons like noise, interference, inter-modulation, echoes, signal fading,
equipment limitations, etc. Though optical fiber medium is considered to be the
best medium, we know that p
Cell phones that have limited coverage areas aren't dependable. As long as you use your cell
phone in a large city where there are plenty of cell phone towers it should work correctly.
However, this isn't always the case, for there are plenty of ways the
Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides resizable compute
capacity in the cloud. It is designed to make web-scale computing easier for developers.

The FCC issues guidelines that govern the installation of telecommunications cabling and the
design of communications devices built or used in the United States. Here are two important
rules issued by the FCC to help prevent problems relating to communica
The type of cable I would use in the new building would be Cat 5e because it can handle
data transfers up to 1000 Mbps which makes it suitable for Gigabit Ethernet. Cat 5e cable was
designed to have a better resistance to near end crosstalk or interferenc
The wired solution for the new building will be as follows. A T1 line from AT&T coming into the
building from that T1 jack I will use cat6 patch cable to the firewall/router. From router one I

This report will illustrate different features that should be included in a typical safety plan for a
new structure. Emergency procedures will also be discussed.
The Safety Overview
Safety is one of those areas that if overlooked could cost you mo
Cable and Optical Fiber Preparation
Step 1: Cut the cable casing approximately 2 longer than required.
Step 2: Install the strain relief boot on the cables end. *Note* the boot will not fit over the
connector, so it must be placed on the connector first.
We will start with FTTB from the outside and continue inside with FTTD.
Outside We will utilize feeder, distribution, and drop cables. Also to be installed is the local
convergence cabinet, the network access point, and the network int
Mechanical splicing involves using mechanical fixtures to align and connect optical fibers.
Mechanical splicing methods may involve either passive or active core alignment. Active core
alignment produces a lower loss splice than passive alignment. However
Describe three factors that could affect splicing performance.
There are 3 factors that affect splicing performance as specified in our text: variations between
optical fiber, alignment, and optical fiber mating issues (which have nothing to be with the f
