WebA novel modulation format, the duobinary carrier-suppressed return-to-zero format, is proposed; its bandwidth is less than 100 GHz at 43 Gbit/s. 100 GHz-spaced DWDM unrepeatered transmission is demonstrated over 163 km at +10 dBm/channel with a crosstalk penalty under 1 dB.
WebMay 24, 2024 · Nonlinear effects have been considered as the major limitations in coherent optical (CO) fiber transmission system. Digital signal processing (DSP)-based CO receiver with digital backpropagation (DBP) method has recently facilitated the compensation of fiber nonlinear impairments as well as compensating dispersion of optical fiber. In this … WebUnrepeatered transmission over a record length of 150 km of nonzero-dispersion fibre at 100 Gbit/s is reported. These results were achieved using decorrelated optical multiplexing of five 20 Gbit/s signals. The transmitter pulse source, the optical demultiplexer and the clock recovery are based on electroabsorption modulators.
