Large-signal spurious-free dynamic range (SFDR) is useful in an optical system with a high intensity noise level, which can be due to optical reflections or optical beat interference, and with large modulating signals to achieve sufficient carrier-to

In this paper, we investigate the ultimate M-ary quadrature amplitude modulated (M-QAM) channel capacity of a laser diode which is limited by the laser clipping induced nonlinear distortions. Our study includes a spectral analysis, a complete system

Due to the stimulating success in developing optical amplifiers, intersymbol interference (ISI) will become the domi- nant limit on both bit rate and transmission distance in long-haul optical fiber communication systems. Here we present a receiver w

We investigate the validity of using multiple continuous-wave (CW) tones as the signal source to test the linearity of a multichannel M-ary quadrature-amplitude-modulation (M-QAM) subcarrier multiplexed lightwave system. We consider the following rep

We propose and verify through computer simulations the use of a precoding technique to eliminate the nonlinear distortions in an M-QAM channel, which is transported along with multiple AM-VSB channels by a laser diode. We show that the precoding tech

Parallel to the evolution process of deep fiber penetration in the CATV subscriber loop will be the matured development of M-ary quadrature amplitude-modulation (M-QAM) modems and MPEG-II codecs, and the gradual replacement of all AM-VSB video channe

By using a 1.3-/spl mu/m external modulation system and a semiconductor optical amplifier, we experimentally demonstrated the feasibility of broadcasting 33 channels of 64-QAM digital CATV signals to eight 70-km optical fiber links. The presented res

A hybrid-fiber coax (HFC) system-based bidirectional CATV communication network relies on the performance of both downstream and upstream optical fiber links. Large (AM-VSB) channel-count, high-power downstream optical fiber transmitters have been co

The main constraint on applying digital intersymbol interference (ISI) cancellation scheme to high-speed optical receivers is the limited processing speed. A novel ISI cancellation technique is given to relax this limitation by doing ISI cancellation
