ITTC Project


Development of 40 Gb/s Test Capability

Project Award Date: 01-01-2001



Description

During the past decade, tremendous advances have been made in the development of high-speed DWM optical systems and networks. To make full use of the optical bandwidth provided by the fiber, WDM channel count has been increased from 4 to 160 in a single fiber and the data rate per channel has also been increased from 622 Mb/s to 10 Gb/s in many commercial optical systems. To further increase the optical bandwidth efficiency, 40 Gb/s optical systems are been developed by several industrial leaders and will be in the commercial market very soon.

The impact of the upcoming 40 Gb/s (OC-768) optical systems to telecommunication service providers, such as Sprint, will be tremendous. On one hand, OC-768 may greatly increase the optical bandwidth efficiency and increase the optical network capacity. But on the other hand, high-speed TDM systems like OC-768 will suffer more from fiber chromatic dispersion, PMD, and fiber nonlinearity compared to OC192 and OC48. Precise dispersion compensation, maybe in the per-channel base, will be required; and the system performance will be more sensitive to fiber types than ever.
A good understanding in 40 Gb/s optical systems will help Sprint in the decision-making process for the technical planning and integration.

The goal of this research it to develop basic capabilities in support of 40 Gb/s optical signal transmission, transport, and reception to support future research thrusts requiring this capability.

We will (1) develop requirements for a 40 Gb/s testbed, (2) design a 40 Gb/s testbed consistent with the available budget, (3) assemble and test the 40 Gb/s testbed, and (4) perform comparisons between different 40Gb/s optical system technologies.

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.
