Bel Fuse and Teranetics Join Forces to Deliver Industry's Highest Density 10GBASE-T Solution

Teranetics' Dual-Port 10GBASE-T PHY and Bel's 2x4 MagJack® Integrated Connector Enable 48 Ports in One Rack Unit

September 15, 2008

JERSEY CITY, NEW JERSEY, September 15, 2008 . . . BEL FUSE INC. (NASDAQ:BELFA) & (NASDAQ:BELFB)- Teranetics, Inc., a leading provider of high performance Ethernet solutions, and Bel Fuse Inc. today introduced the industry's highest density 10GBASE-T solution, which enables switch manufacturers to design up to 48 RJ-45 ports into a single rack unit. The joint solution showcases Bel's G08-8NNR-031 2x4 MagJack® connector along with the recently introduced TN2022, dual-port 10GBASE-T PHY IC from Teranetics.

The 10GBASE-T solution from Bel and Teranetics will allow original equipment manufacturers (OEMs) to design systems that deliver 10 times more bandwidth at nearly one-third of the cost of, and in the same rack space as, existing 1 Gigabit Ethernet systems. The Teranetics TN2022 features multi-rate capabilities, consuming only six watts of power per port at the full 10 Gigabit rate, and operates at cable lengths exceeding one hundred meters. Bel's G08-8NNR-031 MagJack® connector delivers the highest density with its double stack, eight-port format, while supporting Ethernet signal transmission at 10GBASE-T data rates and distances.

"Bel has a track record of delivering high performance magnetics for BASE-T technologies" said Kamal Dalmia, vice president of marketing at Teranetics. "By combining the strengths of our high-performance PHY and the MagJack® integrated connector modules, Teranetics and Bel have set a new standard for port density, cost and performance."

"In addition to providing customers twice the port density, MagJack® connectors do not require OEMs to design-in mezzanine cards or any extra components," said John Hess, MagJack® product manager at Bel. "Coupled with the Teranetics PHY, it's the optimal 10 Gigabit, high-density solution."

Availability and Pricing

The TN2022 dual-port 10GBASE-T PHY transceiver and the G08-8NNR-031 MagJack® connectors are now available in sample quantities. Additional product information and pricing are available upon request.
