AbstractThe numerical modeling of short optical pulses propagation in the communication link is carried out. The combination of high chirp and variable dispersion compensation is proposed to suppress the nonlinear noise. The variable dispersion decreases the bit error rate by 10 times. Calculations for 25 ps pulses propagating by 1000 km with 8-level amplitude-phase modulation and two polarization states confirm that the chirp and compensation decrease the nonlinearity effects and improve the quality of detection radically. The results can be useful when choosing a high-speed communication line design.

Pulse Broadening

Different linear effects that occur in the physical medium are studied and analyzed in this chapter. Specifically, much attention is paid to fiber attenuation, Amplified Spontaneous Emission (ASE) noise due to optical amplifiers, and fiber dispersive effects that cause pulse broadening, which may represent a serious problem in high-speed optical transmission systems. In order to reduce fiber dispersive effects effectively, dispersion compensation fiber is employed. Other effects such as linear crosstalk, which causes distortion and interferes with the filtered channel, can be reduced by optimizing the optical filter bandwidth and shape to obtain a compromise between WDM linear crosstalk and filter induced intersymbol interference (ISI).

AbstractWe demonstrated a full duplex hybrid passive optical network and indoor optical wireless system employing coherent optical frequency division multiplexing. To accomplish reliable transmission in passive optical networks integrated visible-light communication (VLC), yellow light-emitting diode and infrared LED is used in downstream and upstream, respectively, for intra building network. In order to support high data rate, pulse-width reduction scheme based on dispersion compensation fiber is incorporated and system successfully covered the distance of 50 km. A data stream at the rate of 30 Gb/s is transmitted for each user out of eight users. VLC-supported users are catered with the bit rate of 1.87 Gb/s over 150 cm and in order to realize a low-cost system, visible and infrared LEDs are used in downlink and uplink, respectively.

Shift Keying

AbstractThe modulation and demodulation methods of the optical Differential Quadrature Phase Shift Keying (DQPSK), Optical Differential Phase Shift Keying (DPSK) and the different modulation formats including nonreturn-to-zero (NRZ), return-to-zero (RZ), carrier-suppressed return-to-zero (CS-RZ) are introduced, studying the ability of anti-dispersion for different optical signals in the 40 Gb/s high speed transmission system. The system is simulated in optical fiber by way of dispersion compensation. And then analyzed the compensation effect of the different dispersion compensation method for different phase modulation formats. It is shown that the ability of anti-dispersion and anti-PMD is better in the CS-RZ-DQPSK modulation format, and this format has the smallest eye-opening penalty (EOP) with a wider range of power into the optical fiber.
