In the design of distributed erbium-doped fibers (DEDFs) for ultra-high bit-rate (> 40 Gbit/s) soliton transmission, polarization mode dispersion (PMD) is an important design parameter.

We show that DPSK systems can tolerate more PMD than OOK systems, and that CSRZ has a different feature from RZ with respect to PMD, because of its specific spectrum and phase characteristics.

The polarization mode dispersion (PMD) tolerance of different modulation formats is studied, including on-off-keyed, differential-phase-shift-keyed (DPSK), and carrier-suppressed return-to-zero (CS

We propose an in-band optical signal-to-noise-ratio (OSNR) monitoring technique. The technique uses the polarization characteristics of two narrow bandwidth filtered optical spectral components.

The effect of rotation of the principal states of polarization is investigated by using a dispersion-compensated system and focusing attention on wavelengths in the fiber polarization-mode-dispersi

The interaction of intra-channel effects and polarization mode dispersion in 40 Gb/s transmission systems can support signal propagation by reducing the non-linear impairments.

The mitigation of polarization mode dispersion (PMD) in lightwave systems has been an elusive goal. Optical techniques can provide perfect mitigation in theory but add cost.

We measured the performance of a 10 Gb/s received having a threshold that automatically adjusts to the optimal value.

We present two schemes extending the KK-receiver so as to accommodate for polarization multiplexed transmission.

A statistical analysis of the polarization pattern of low-frequency geomagnetic field fluctuations (0.8-3.6 mHz) covering the entire 24-hour interval has been performed at an Antarctic station (Ter
