EMCORE receives active optical cable patent

MARCH 18, 2009 -- EMCORE says its expects active optical cable technology will replace copper cables in 40-Gbps applications and beyond.

MARCH 18, 2009 -- EMCORE Corp. (search Lightwave for EMCORE), a provider of compound semiconductor-based components and subsystems for the broadband, fiber-optic, satellite, and terrestrial solar power markets, has received a patent award for its Active Optical Cable technology. US Patent No. 7,494,287 B2 with broad claims covers all fiber-optic active cable applications, and the company believes it to be fundamental to current and future market segments and platforms related to data communications links between information systems.

Today's high-speed data communications networks utilize optical fiber cables for data transmission between information system units such as computer clusters, mass data storage devices, and routers. Typical systems communicate via electrical host adapters that when connected to electro-optical transceivers mated with an optical fiber cable enable high bandwidth, low latency, lightweight, and improved airflow in data networks.

According to the Active Optical Cables Market Study 2009 by Information Gatekeepers Inc., the overall cumulative cable revenue from 2009 through 2013 is expected to exceed $8.5 billion. This represents a total of 1,040 million meter cables cumulative for the five years.

"EMCORE previously announced supporting IBM's use of 55 miles of our active optical fiber for the world's first petaflop supercomputer," says Stephen Krasulick, Executive Vice President and General Manager of EMCORE's Fiber Optics Products division. "For next-generation 40-Gbps and greater bandwidth applications we expect active optical cables to replace copper cables and become the dominant connect solution."

The company currently sells in high volume the EMCORE Connects Cables (ECC) product platform for high-performance InfiniBand interconnects that operate at 20-Gbps data rates and is sampling next-generation 40-Gbps data-rate cables to OEMs.

EMCORE will demonstrate the new 40-Gbps ECC at OFC/NFOEC 2009, Mar. 24-26 in San Diego, CA. EMCORE Connects Cables currently support 40-Gbps quad data rate (QDR), 20-Gbps double data rate (DDR), and 10-Gbps single data rate (SDR) and are available in lengths from 1 to 100 m.
