Optical transmitter and receiver rise time

Rise time is defined as the time taken by a signal to rise from 10% to 90% of its maximum amplitude. In optical communications, rise time is typically measured in picoseconds (ps) or nanoseconds (ns). tio, rise and fall time, and jitter. It is the re-sponsibility of the designer to ensure that the transmitter meets all the relevant re-quirements for th esents. Modal Noise: When a laser is coupled to a multi mode fiber (MMF) modal noise exists. To avoid this,• Total rise time depends on: – Transmitter rise time (ttx) – Group Velocity Dispersion (tGVD) – Modal dispersion rise time (tmod) – Receiver rise time (trx) Total rise time of a digital link should not exceed 70% for a NRZ bit period, and 35% of a RZ bit period 1/2 1 2      =∑ N i tsysti. The analysis is based on normal receiver sensitivity assuming an ideal input signal with negligible impairment such as ISI, rise/fall time, jitter, and transmitter relative intensity noise (RIN).
