Fiber Optics (Transmission Media
Class, Fiber Optics Section) with
Complete Solutions
Mode Field Diameter - ANSWER - The diameter of the light emerging from the end of
the fiber is also termed...
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
