ITTC Project


PMD Characterization of Installed Fiber

Project Award Date: 05-01-2003



Description

The goal of this effort is to gain a better understanding of how polarization-mode dispersion (PMD) varies on installed (buried) fiber cables and how this behavior might impact the reliability of a a fiber-optic network.

Previous PMD work conducted in ITTC's Lightwave Communication Systems Laboratory involving dark, installed Sprint-owned optical fiber has provided an improved insight regarding the potential challenges posed by PMD at data rates at and above 10 Gb/s. This is a continuation/extension of this work.

The core within a fiber optic cable has to be perfectly circular to work correctly. Otherwise, data traveling through it get messed up. Changes in temperature, pressure and other stresses also make the cable unpredictable.

Meanwhile, increasing amounts of information are being transmitted over cable. Internet communication involves words and pictures, audio and video files; as it all gets pushed through cable, the likelihood of scrambling goes up.

At current data rates, PMD is so small that it goes unnoticed. It becomes a significant problem at higher data rates, which are needed to provide greater network capacity.

Partner with ITTC

The Information and Telecommunication Technology Center at the University of Kansas has developed several assistance policies that enhance interactions between the Center and local, Kansas, or national companies. 

ITTC assistance includes initial free consulting (normally one to five hours). If additional support is needed, ITTC will offer one of the following approaches: 

Sponsored Research Agreement

Individuals and organizations can enter into agreements with KUCR/ITTC and provide funds for sponsored research to be performed at ITTC with the assistance of faculty, staff and students.

Licensing and Royalty/Equity Agreement

An ITTC goal is the development of investment-grade technologies for transfer to, and marketing by, local, Kansas, and national businesses. To enhance this process, the Center has developed flexible policies that allow for licensing, royalty, and equity arrangements to meet both the needs of ITTC and the company.

Commercialization Development

Companies with a technology need that can be satisfied with ITTC's resources can look to us for assistance. We can develop a relationship with interested partners that will provide for the development of a technology suited for commercialization.

ITTC Resource Access

ITTC resources, including computers and software systems, may be made available to Kansas companies in accordance with the Center's mission and applicable Regents and University policies.
