Novel technologies to improve spectral efficiency and lower power consumption in optical transport networks (OTNs) have been recently studied and developed..

Traffic engineering based on cross-layer communications to counter-act inter-channel impairments in optical networks is shown to yield significant throughput gains for a variety of traffic models.

We measure impairment of on-off-keyed and differential-phase-shift-keyed signals imposed by gain saturation in a fiber parametric amplifier.

Binary-phase-shift-keyed pump modulation suppresses stimulated Brillouin scattering in fiber parametric devices.

Applying bit-to-bit alternate-polarization modulation at 43 Gb/s in ASK/DPSK formats, we found experimentally non-linear threshold benefits up to 4 dB with RZ and 2 dB with NRZ, reduction of DGD to

HE rapid increase in the demand for long distance or toll telephone service in recent years led to the introduction, about 1920, of carrier systems as a means of securing more intensive use from lo

We study the influence of electrical connection methods on the high speed performance of electro-absorption modulators (EAMs).

A knowledge of the impedance characteristics of loaded lines is of considerable importance in telephone engineering, and particularly in the engineering of telephone repeaters.

T HE transmission of alternating currents over any transmission line between specified terminal impedances depends only on the propagation constant and the characteristic impedance of the line (at
