If one were to transmit such information without impressing it on an optical carrier but instead on a radio frequency carrier , the transmission wavelength of the RF carrier would be centimeters or larger.
A.
without the impression that an optical carrier can replace a radio frequency carrier
B.
without pressing an optical carrier but instead pressing a radio frequency carrier on it
C.
without modulating an optical wave but instead a radio frequency wave
D.
this delay must indeed be no more than one internal bit
