Negligible
Answer is Right!
Answer is Wrong!
The correct answer is: A. Less than the reciprocal of broadened pulse duration.
The broadened pulse duration is the time it takes for a light pulse to spread out after it has been launched into an optical fiber. The digital bit rate is the number of bits that can be transmitted per second. In order to avoid overlapping of light pulses, the digital bit rate must be less than the reciprocal of the broadened pulse duration. This is
