Digital Subscriber Line technology has democratized broadband access, and over the past several decades, telecommunications providers have evolved from providing plain old telephone service (POTS) over a copper loop plant to providing broadband acces

Continuous improvements in communication technologies over copper pair access networks have enabled hybrid fiber/copper access networks that provide ever increasing broadband data rates. Most recently, field trials have demonstrated that crosstalk ca

Nonlinear Tomlinson-Harashima precoding has been proposed as a near-optimal interference mitigation technique for downstream transmission in G.fast systems, particularly in the transmit spectrum above 106 MHz. We propose an alternative implementation

This article explores the recently issued ITUT G.vector (G.993.5) that allows expanded use of 100 Mb/s DSL. A tutorial description on G.vector's crosstalk noise reduction methods leads to specific projections and measurements of expanded DSL 100 Mb/s

A large deviations principle (LDP), demonstrated for occupancy problems with indistinguishable balls, is generalized to the case in which balls are distinguished by a finite number of colors. The colors of the balls are chosen independently from the

We extend studies on power optimization in VDSL2 to G.fast, the technology under definition. In vectored G.fast the power of the signals before precoding needs to be optimized to meet power spectral density and maximum aggregate tarnsmit power constr

The design and analysis of control strategies for high-capacity, reconfigurable optical transmission systems require an understanding of optical system dynamics involving the time-dependent interaction of many components. This paper describes system

One way for service providers to reduce their costs is through network capacity recovery. We describe the problem of recovering capacity by minimizing the switching overhead incurred by multiple switches in a switching center. We also describe the Mu

This paper describes the subsystem design and performance of a 256/spl times/256-port micromechanical beam-steering optical cross-connect with 1.33-dB average loss, which can provide 238/spl times/238-port cross-connect with a maximum loss of less th
