: We demonstrate the generation and detection of a novel reduced-guard-interval CO-OFDM signal at 448 Gb/s, occupying 60-GHz optical bandwidth.

We demonstrate am optically labeled signal based on return-to-zero (RZ) differential phase-shift keying (DPSK) for payload at 10-Gb/s and amplitude-shift keying (ASK) for label at 622-Mb/s.

Transmission of digital information between central offices in the same or different cities is a basic process necessary to establishing a connection between subscribers.

A quantitative measure of " i n f o r m a t i o n " is developed which is based on physical as contrasted with psychological considerations.

By using asymmetrical interleavers, carrier-suppressed polarization-division-multiplexed quadrature-phase-shift-keying (CSRZ-PDM-QPSK) and coherent detection, we successfully transmit a mix of 224-

Using pulse shaping and maximum-likelihood detection techniques, we successfully transmit a mix of 260-Gb/s PDM-16QAM and 130-Gb/s PDM-QPSK channels at a 50-GHz channel spacing over 960-km and 4160

Pseudo-linear transmission of short pulse OTDM signals has enabled transmission of high bit-rate OTDM signals over optical fiber that has nonzero-dispersion.

The relationships of hydromagnetic energy in the band ~20-50mHz, as measured on the ground near a dayside magnetopause field line, to the total magnitude of the interplanetary magnetic field (IMF)
