November Meeting
November 6 , 2007
Doubletree, Waltham, MA

Topic:
Topic: Advances in Bend-Insenitive Singlemode Fibers
for High Density FTTH applicatons


First Speaker:
Paulo Dainese, Corning

The latest trend in optical fiber is the advent of bend-enhanced fibers. As carriers continue to work through the complexities associated with bringing fiber closer to the home or office, there is a general realization that optical fiber will be deployed in an increasingly more demanding environment. Additionally, there is an immediate market need to address issues associated with fiber-to-the-home deployments in apartment and condominium complexes: lowering costs, cutting installation time, and reducing the aesthetic impact of passive solutions. These requirements coupled with the need to protect the carrier's optical budget presents significant opportunities to create value with new fiber and passive equipment design.

The following topics were covered:
• Market trends driving bend fiber development
• Specific MDU requirements and carrier needs around the world
• The optics: what is happening in the glass and methods to improve bend performance
• Standards development
• Mechanical reliability at newly specified bend radii
• Impact on field procedures and equipment.

Paulo Dainese is currently a Market Development Analyst for Corning Incorporated concentrating his efforts on uncovering new fiber types to support emerging technologies. Dainese holds a Ph.D. in Physics from the Gleb Wataghin Physics Institute at the State University of Campinas in Brazil.

Second Speaker:
David Mazzarese, OFS

High definition on demand video is driving bandwidth requirements for FTTX networks toward speeds greater than 1-Gbit/s. The passive optical network comprises a small part of the total network cost yet will have to support several generations of electronics over networks lifetime. One of the most difficult challenges currently facing service providers is controlling added loss caused by the fiber bends, particularly for bend-sensitive video wavelengths used in FTTX, enterprise, and hybrid fiber/coax networks. The combination of tight power budgets and conventional singlemode fiber can shut down video services in today's compact, bend-challenged networks.

David Mazzarese, OFS, is the Optical Fiber Technical Marketing - Global Manager. He currently supports the entire optical path. Prior to this, he spent over 10 years leading the development of various multimode, singlemode and specialty fiber products. He holds a PhD in Chemical Engineering and an MS in Electrical Engineering from the University of Massachusetts at Amherst.
