These types of optical couplers have one input and two outputs.
What is a "T" or "Y" coupler?
100
The National Electrical Code (NEC) is updated this often.
What is every three years?
100
These are the 2 standard core sizes for multi-mode optical fibers.
What is 50um and 62.5um?
100
This tool permits close-up inspection of polished end face finishes/.
What is an inspection microscope?
100
This tool is used to remove high order mode wavelengths from a multi-mode cable when using a LED light source.
What is a mode filter or mandrel?
200
This device will increase the light signal without the need for a repeater.
What is an amplifier?
200
Bending an optical fiber will decrease this physical charateristic...
What is the tensile strength?
200
This tool is used by a technician or installer to test a new reel of fiber prior to installation.
What is a VFL or continuity tester?
200
When inspecting a connector, minor defects are only allowed in this part of the of optical fiber.
What is the outer cladding?
200
This test method uses only one test jumper to establish a reference between a fiber optic light source and the power meter.
What is Method B?
300
This type of passive device will only permit the forward transmission of light.
What is an optical isolator?
300
Tensile loads that are that are on a cable under normal operating conditions are called this type of load.
What is static or long term load?
300
This type of connection does not produce any type of back reflection.
What is a fusion splice?
300
This parameter in the OTDR setup is essential to establish the distance of the dead done and the maximum length that a fiber will be tested.
What is pulse width?
300
An OTDR can be used to determine length, isolate faults, and evaluate the these two types events.
What are connections and splices?
400
This type of device will allow wavelengths of light to pass or be rejected.
What is a filter (pass or reject)?
400
This is the rule of thumb for the maximum bend radius under a dynamic tensile load.
What is 20 times the cable diameter?
400
These are the 7 advantages of fiber optic cable over copper cables.
What is bandwidth, electromagnetic interference, low loss, weight, size, safety and security?
400
This test equipment would be used to determine the amount of loss and total distance of a fiber optic link.
What is an Optical Time Domain Reflectometer (OTDR)?
400
In order to most accurately determine the distance of a link, this specification must be correctly set in the OTDR.
What is the fiber's index of refraction?
500
This specific type of device is used to combine different wavelengths of light for transmission onto one optical fiber.
What is a wavelength division multiplexer?
500
This article of the National Electrical Code (NEC) requires that all conductive cables entering a building must be grounded.
What is Article 250?
500
An OTDR uses this to identify events in a fiber optic cable.
What is backscattering of light? (reflectance)
500
A fiber optic source and power meter is used to measure this parameter.
What is loss or attenuation?
500
Entering an higher index of refraction than the correct index of refraction into the OTDR will result in this type of inaccuracy during a distance measurement.
