Non-return-to-zero (NRZ), non-return-to-zero-inverted (NRZI), return-to-zero (RZ), and Manchester are popular serial encoding mechanisms. Each has different characteristics that make it useful in ...
RZ pulse signaling is increasingly being used in ultra-long-haul systems because its robust bit-error rate (BER) performance allows longer span lengths between the ...
The world's appetite for faster communications now pushes the development of 40-Gbits/s optical-network components. At such a high data rate, the familiar non-return-to-zero (NRZ) signaling method ...
