Digital Fiber Optic Communication Jitter
Learn about its types, effects, causes, and ways to measure and reduce jitter. Jitter: Jitter is the short-term phase variations of the significant instants of a digital signal from their ideal positions in time. The consequences include: Increased Bit Error Rate (BER): This is the most direct impact. Four kinds of jitter are identified: duty cycle distortion, data dependent, and uncorrelated (to the data) bounded. Systematic jitter occurs in relation to the transmission pattern and is caused by the interference between the signals in each part of the equipment--AM/FM conversion, clock recovery de-tuning, etc.
