Attenuation distortion is a basic measure of the quality of a transmission channel.

Fiber-optic technology has created the opportunity for the development of underwater communications cables which are much smaller than those used in the past.

To assess the threat of undersea cable failure due to abrasion caused by vortex-induced vibrations, a series of experiments were conducted in which a length of vertical cable with a clump weight at

We measured intermodulation distortion generated by the presence of two optical tones separated by up to 1 GHz in a 1.3micron near-travelling wave optical amplifier.

We demonstrate the reconstruction of constellation diagrams for 40-Gb/s DQPSK and 60-Gb/s 8ary- DPSK signals using orthogonal differential direct-detection and analog-to-digital conversion.

We demonstrate the reconstruction of constellation diagrams for 40-Gb/s DQPSK and 60-Gb/s 8ary-DPSK signals using orthogonal differential direct-detection and high-speed analog-to-digital conversio

The Muller Matrix Method enables the low-noise, high-resolution measurement of second-order polarization-mode-dispersion (PMD) depolarization and related parameters required for systems modeling.

T h e dielectric a n d m a g n e t i c properties of semi-conducting ferromagnetic materials such as ferrites have been t h e subject of intense s t u d y in recent years.

The wavelength-drift under burst-mode operation is evaluated. A fast drift at start of burst is found that has inverted sign compared to thermal drift.

Group velocity dispersion spectra have been determined for 7.8-m lengths of single-mode optical fiber.
