Unit 8 Assignment 1
Poor concentricity, noncircularity, and end separation are three factors that could affect splicing
performance. The concentricity issue is caused by the two cores on the splicing ends misaligning
Basic service set- a single access point together with all associated stations; mesh topology
Extended service set- a set of two or more interconnected wireless BSSs that share the same
SSID, security credentials and integrated wire
LAB 4 Copper Cabling
Why are the standards so important for NICs, connectors, and media? The standards for the NIC
allow for computers to communicate with each other, therefore the connectors need to be comparable
to use with computers to a
There are no limitations on WANs so they can be custom built for the size of the

1. You can only compress one string of 0s because if you compress both you lose count of
how many you can expand.
C. Two consecutive strings of 0 values were hidden.
2. Uniqueness is given because the first half of the

Crosstalk: Unwanted transmission of signal between lines.
Simplex: Signal that only goes in one direction
Light-emitting diodes (LEDs) emit a wide spectrum of unnoticeable light. The usual
optical communications output is about 30-60nm, though this is gradually increasing with
technology. Because of this, it is more susceptible to dispersi

light based on the properties of the material used.
1854- John Tyndall proved that light signal could bend by sending a light beam down a tu
Crimpers: Tool used to connect a cable to the connector.
Continuity Tester: Tool that once hooked to a part of a cable, tests the signal to ensure that there
are no breaks within it.

1. What tools would you need to install a twisted-pair cable connector?
Cable stripper, crimper, punch down, length measurement tools (TDRs), cutting tools
2. What is a fiber-optic microscope used for when installing a connector on a fiber-optic cable?
Copper vs. Fiber Optic
Copper is more prevalent than optic fiber because it is more attainable, cheaper, and
easier to work with. While wiring cannot be reused, the copper in the actual wire can come from
a recycled source. This is one
