“…As the method is based on moments, it is well suited to be used with sampling histograms. It is currently common practice to extend the achievable link reach by using optical amplification (Di Giovanni et al 2002) and clearly the validity of the new metric is restricted to the cases when the resulting ASE noise is the dominant signal impairment. In link scenarios where there is no optical amplification, or when the optical signal-to-noise ratio is very good, other noise sources (e.g.…”

Optical signal quality metric based on statistical moments and Laguerre expansion

A new and straightforward optical signal quality metric, which is based on the approximation of the analytical probability density function by its Laguerre expansion, is proposed. This expansion uses statistical moments to approximate the true statistics, but, unlike the well-known Gaussian approximation, higher order moments can be used as well. The quality of the proposed metric is discussed and the metric is compared with the Gaussian approximation. It is shown that the new metric provides not only a good estimation of the bit error rate in the range of practical interest but, contrary to the Gaussian approximation, correctly estimates optimum decision threshold and accurately pictures the shape of the noise distribution.

“…На сегодняшний день разработан новый класс микроструктурированных оптических волокон, которые содержат ряд отверстий, расположенных продольно вдоль оболочки оптокабеля [1]. Так как микроструктура волокна всегда является высокопериодичной, данные волокна обычно называются фотонно-кристаллическими волокнами (ФКВ) или дырчатыми волокнами [2].…”

“…Twisted optical fibers have been known since the early 1980s: here the concept of fiber spinning was originally introduced for the first time in the work of [1], and it is based on rotation of preform during the fiber drawing [1] or direct spinning of the drawn fiber instead of preform [2]. For single-mode optical fibers, the described technique is declared as the method for polarization mode dispersion (PMD) reduction [1][2][3][4], while for multimode optical fibers, induced chirality (including twisting) is considered as one of the methods for differential mode delay (DMD), decreasing with total bandwidth improvement [5,6]. Twisted large core optical fibers are associated with great potentiality for applications in high-power fiber lasers with either active optical fibers with a higher-order modesuppression property [7] or optical fibers with improved mode coupling for cladding pumped devices [8].…”

This work presents fabricated silica microstructured optical fiber with special equiangular spiral six-ray geometry, an outer diameter of 125 µm (that corresponds to conventional commercially available telecommunication optical fibers of ratified ITU-T recommendations), and induced chirality with twisting of 200 revolutions per minute (or e.g., under a drawing speed of 3 m per minute, 66 revolutions per 1 m). We discuss the fabrication of twisted microstructured optical fibers. Some results of tests, performed with pilot samples of designed and manufactured stellar chiral silica microstructured optical fiber, including basic transmission parameters, as well as measurements of near-field laser beam profile and spectral and pulse responses, are represented.
