Infonetics Research: New white paper evaluates if/when service providers should upgrade to 40G

CAMPBELL, CA--(Marketwire - June 12, 2008) - Communications market research firm Infonetics Research announced a white paper today detailing the advantages and disadvantages of various solutions on the market that allow carriers to upgrade their optical networks to 40G to more efficiently handle the ever-growing bandwidth needs of consumers and businesses.

The white paper, Cost Considerations in 40G Networks, examines the 4 main modulation schemes being used or considered for 40G and 100G upgrades, including Duo-Binary, DPSK, DQPSK, and DP-QPSK. Each of these techniques attempts to minimize the various problems inherent in pushing more data through optical fiber, while minimizing the cost of the equipment.

"Today, optical backbones and metro core networks are predominantly 10G, on the verge of moving to 40G. But the challenges in the previous move from 2.5G to 10G are minor compared to those of moving from 10G to 40G, and the challenges moving on to 100G are even more daunting. Carriers would like to upgrade to 40G by just inserting new 40G cards into their existing 10G WDM systems, but this may not be possible. The ideal solution for upgrading to 40G (and 100G), would be one that doesn't require changing the network design, buying totally new equipment, or investing in new, expensive fiber," said Michael Howard, principal analyst at Infonetics Research and author of the white paper.

Infonetics' white paper includes a 2-page Checklist of 40G Purchase Considerations and addresses key questions such as:

--  What is driving the bandwidth growth in networks today and in the next
    few years?
--  What are the 3 basic challenges when upgrading your network to 40G?
--  What are the advantages and disadvantages of present 40G offerings?
--  Should you upgrade to 40G, or wait for 100G?
