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

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

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

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
