core, cladding, and prime coating - ANSWER The basic construction of fiber is:
zig-zag - ANSWER A multimode step-index fiber transmits light down the fiber in what pattern?
Single-Mode - ANSWER This type of fiber has only one mode for the light to travel down.
glass core and plastic cladding - ANSWER Plastic-clad silica cables have what kind of construction?
material dispersion - ANSWER different wavelengths travel at different speeds along the same path
5-10 micrometers - ANSWER the typical core diameter range for single-mode fiber optic cables
125 micrometers - ANSWER typically the cladding of a fiber, regardless of its core size is what diameter?
waveguide dispersion - ANSWER a singe wavelength travels at different speeds in different materials
.50 km - ANSWER if you are using a fiber optic cable that is designed to transmit 600 MHz for a distance
of .75 km, how far could an 800 MHz signal travel on the same cable
microbend loss - ANSWER little bumps in the core at the junction of the core and cladding are called?
, frequency goes up - ANSWER distance goes down
attenuation - ANSWER dB/Km is how ________ of optical power is measured
numerical aperature - ANSWER The _______ ________ of the optical source, fiber, and optical receiver
must match for best transmission
tight buffer - ANSWER allows a lower tensile strength but a higher impact and crush resistance
plenum-duty fiber - ANSWER type fiber used if you are installing it in a return air vent / space in a
building
strength members - ANSWER the part of the fiber optic cable that allows you to pull it when you are
installing it
MHz per Km - ANSWER many manufacturers specify bandwidth-length in ______ instead of specifying
dispersion in the modal offerings
300 dB/Km - ANSWER plastic fiber would have an attenuation in the range of
Graded Index Fiber - ANSWER fiber optic cable constructed by layers of increasing index of refraction
core material
single mode fiber - ANSWER when using ________ fiber optic cable you must worry about matching the
cable to the frequency of the light you are transmitting more than other types of cable
single mode fiber - ANSWER has smaller core so it is particular about light frequency
modal dispersion - ANSWER doesn't exist in single mode fiber (zig-zag flatlines out)
