Bit rate The number bits data transmitted over a
phone line per second.
Chromatic dispersion The speed optical
pulse travelling ber changes its wavelength
changes.
Bit (Binary Digit) basic unit for the datas a
digital transmitting system.
Capacitive Coupling Electrical interaction between
two conductors caused the capacitance between
them.
Circuit Sizes popular term for building wire sizes 14
through AWG.
AWG Abbreviation for American Wire Gauge. group Bit usually
expressed one Byte.

Capacitance (Capacity) That property system of
conductors and dielectric which permits the storage of
electricity when potential difference exists between the
conductors.
Cellular insulation Insulating material foamed or
sponge form with the cells closed interconnected. Generally attenuation increases
(signal level decreases) with both frequency and cable length.
