Testing should be performed using an organized systematic method. Which of the following is Phase 1 method

Testing should be performed using an organized systematic method. Which of the following is Phase 2 method

Testing should be performed using an organized systematic method. Which of the following is Phase 3 method

Troubleshooting a problem in a customers cabling system involves, Check all that apply

Troubleshooting is an __________________ process

These types of test equipment are used for which of the following, (wire map, multimeter, TDR, butt set, inductive amplifier,...

Certification test sets are used to verify that a cabling system meets transmission performance requirements. These link parameters are defined in which applicable standards. Check all that apply

What is the frequency range for Category 6a

Nominal velocity of propagation ( NVP) is used to determine

This coefficient is used to determine the speed of transmission along a cable relative to the speed of light in a vacuum, typically expressed as a percentage.

Factory calibration may be required every 18 months for certification test sets.

A good rule of thumb is to perform the field calibration at least_________ or ______________ a new series of tests. (Check all that apply)

An *PASS or *FAIL is often referred to as the _________ _________ or a __________ ___________ . Check all that apply

Pairs within a 4 pair cable use a different twist length to improve NEXT. A physical difference in length between pairs is referred to as

When addressing copper media, __________________ is the loss in power as it travels along a cable, increases with temperature, frequency and cable length as well as improper terminations and equipment cords.

___________ is the unwanted signal coupling between pairs, It is measured at the end of a cable nearest the point of transmission.

__________________ is a ratio of the outgoing signal to the power of the reflected signal expressed in dB.

Because of the twisting of the pairs, the actual physical length of balanced twisted pair cable will appear slightly shorter than the electrically measured length.

Prior to Optical fiber installation, the installer and the client should determine what field tests should be performed to include these as a minimum. Check all that apply

Pre-installation testing should start with a check that the fiber type is correct. testing can be done with a visual fault locator(VFL), optical loss test set (OLTS), and an optical time domain reflectometer (OTDR). Of these three, which can be used using only one end

Acceptance testing is accomplished by using which of the folowing

This tool is used to inspect the end face of the optical fiber connector for radius of curvature, offset of polish and optical height.

Microscopes greater than 200x power, tend to make the smallest defect look much worse than it actually is.

For bi-directional testing at both wavelengths at one time the test instrument to be used is

A current certificate of calibration of the tester may be required as part of the projects documentaion requirements.

All values of attenuation for cable, connectors, and splices provided in any standard or specification are stated as being the maximum allowed loss values accepted by the standard.

Connector insertion loss is often stated in cabling components standards as _______ dB per mated pair for both multimode and singlemode, but all products should be better than _______ per mated pair.

The splice insertion loss allowance for LAN cabling standards is 0.3 dB per splice regardless if it is mechanical or fusion, single mode or multi mode.

Bandwidth for optical fiber circuits cannot be measured in the field or proven through calculations by installer.

The _______ jumper method is the preferred referencing method for most installed optical fiber systems.

This tester locates and detects faults and determines the amount of signal loss at any point in the optical fiber.

The OTDR trace ___________ replace the need for the OLTS testing.

This tester uses Rayleigh scattering and Fresnel reflection to measure characteristics of an optical fiber.

_______________ wavelengths of light exhibit greater amounts of attenuation in the same optical fiber because of their higher sensitivity to Rayleigh scattering.

_____________ wavelengths are more sensitive to bending loss.
