A Response to Assertions that Fiber Manufactured in a Clean Room is Stronger and Less Susceptible to Fatigue

From time to time it has been asserted that making fiber in an "ultra-clean" environment could improve optical fiber strength and make the optical fiber less susceptible to fatigue failure and subcritical crack growth. In particular, recently a manufacturer has implied that by making fiber in a clean room, strength values close to the theoretical strength of glass can be obtained. Because of the historical importance of this topic to Corning and the inaccuracy of the above claims we felt it necessary to provide a technical response.

An Introduction to the Fundamentals of PMD in Fibers

This white paper provides an overview of polarization mode dispersion as a limitation on fiber links. Understanding the challenges presented by PMD is becoming increasingly important as network data rates continue to rise.

An Overview of ITU-T G.657

This white paper provides and overview of the ITU-T G.657 standard and summarizes the two categories of fibers described in the standard.

Broadband Technology Overview

This paper reviews the latest developments in the leading broadband access technologies and we assess the ability of those technologies to meet the future requirements of the broadband consumer. We compare and contrast those technologies to the advantages of fiber to the home to determine whether fiber continues to offer the ultimate in broadband connectivity.

Explanation of Reflection Features in Optical Fiber as Sometimes Observed in OTDR Measurement Traces

This white paper explains how refection features are sometimes observed in optical fibers and how reflections may be characterizes by OTDR measurements, and if present, how they can be related to Corning’s ORL specifications.

Standard Single-Mode Fiber Upgrades to Full-Spectrum and G.652.D
[ available languages: English | Chinese ]

Telecommunications network technology continues to evolve, with today’s networks providing faster, more reliable and more ubiquitous connections at lower costs than ever before. Optical fiber, due to its superior transmission capability, forms the foundation for today’s optical networks. As network complexity, flexibility and cost-sensitivity have evolved, single-mode fiber has undergone significant change since its inception in telecommunication networks in the 1980s. Corning® Optical Fiber and the world’s other leading optical fiber manufacturers continue to innovate to ensure that fiber attributes meet these changing network demands. In order to unleash the vast potential of optical fiber, it has become increasingly critical for network designers and operators to select the appropriate optical fibers to support existing and emerging system technologies.

Statistical PMD Specification - Evolution, Utilization and Control (Conference Paper)

Polarization mode dispersion (PMD) is a primary consideration in today’s telecommunications networks as it can be an important limiter of high data rate (10 - 40+ Gb/s) and long reach (one to several thousand km) systems. High performance systems with extended repeater spacing and high transmission speeds can be facilitated by the proper specification and control of PMD, thereby reducing costs and maximizing the value of a communications network. This presentation and paper was presented at the 2005 OFC/NFOEC Conference.
