TL;DR: In this article, the system penalties induced by polarization mode dispersion (PMD) in a 5 Gb/s optically amplified link were analyzed and a relation between differential group delays and system penalties was obtained from numerical simulations and used to derive analytic formulas for probability density functions of system penalties.
Abstract: The system penalties induced by polarization mode dispersion (PMD) in a 5 Gb/s optically amplified link are analyzed. A relation between differential group delays and system penalties is obtained from numerical simulations and used to derive analytic formulas for probability density functions of system penalties. Cumulated probabilities show that PMDs higher than 20 ps can induce significant fluctuations of the bit-error-rate (BER). Characterization of a 6200 km optically amplified link indicates that the relative contribution of PMD to these fluctuations is not significant when PMD is limited to 0.1 ps//spl radic/km. >

TL;DR: In this article, a polarization-maintaining and absorption-reducing (PANDA) fiber was proposed, which provides large modal birefringence and low-loss properties.
Abstract: Single-mode and low-loss optical fibers maintaining a state of polarization over a long length are necessary for coherent optical communication and fiber-optic sensing systems.1 Stress-induced birefringence fibers as reported so far show the high losses.2 Polarization mode dispersion (PMD) of these fibers is measured to be of the order of 50300 psec/km, which causes degradation of the receiver sensitivity in coherent optical communication systems. This paper presents polarization-maintaining and absorption-reducing (PANDA) fibers, which provide large modal birefringence and low- loss properties. Furthermore, the structure of PANDA fibers with zero PMD is proposed.

TL;DR: The fundamental advantages and drawbacks of 40-Gb/s systems from a fiber manufacturer's perspective are reviewed and the fiber design parameters with the expected performance of long-haul systems operating at 40 Gb/s are correlated.
Abstract: In this paper, we review the fundamental advantages and drawbacks of 40-Gb/s systems from a fiber manufacturer's perspective. Based on modeling, experimental results, and fundamental understanding, we correlate the fiber design parameters with the expected performance of long-haul systems operating at 40 Gb/s. Nonlinear penalties, dispersion tolerances, modulation formats, polarization-mode dispersion, and Raman amplification are covered. We also present the fiber features required for both metro and submarine networks at this specific data rate.
