Sumitomo Electric Reaches Milestone Of 10 Million Laser Diodes Shipped

Tokyo — Sumitomo Electric Industries, Ltd. (SEI) recently announced it has now shipped more than 10 million semiconductor laser diodes (LD) for the optical fiber communication applications since its first shipment in 1991. SEI manufactures high-performance distributed-feedback (DFB) and Fabry-Perot LDs for use in advanced optical communications. Applications include metropolitan access networks, fiber to the home, local and storage area networks, cable television, and point-to-point cellular networks.

"Reaching this milestone demonstrates the confidence that customers have in our performance, reliability, and ability to meet the evolving demands of the market," said Ichiro Kono, General Manager of SEI's Optical Transmission Component Division. "Despite the upheavals and turmoil in the optical component market over the past decade, we have consistently and reliably supplied leading-edge optical technology worldwide."

The growing SEI laser portfolio includes wafers, chips, packaged devices, and transmitters and transceivers. The DFB-LDs offer low-voltage and high-efficiency operation across the spectrum from 1200 nm to 1600 nm. DFB-LD shipments alone are expected to pass five million by May 2007. The Fabry-Perot LDs are the foundation of lower cost transmission applications that do not require the performance of the higher-end DFB LDs.

SEI produces the laser diodes in Japan and China. With ISO 9001-certified facilities and a global reputation for quality, SEI is known for producing highly reliable products, with an enviable industry-leading LD device failure rate of only 0.02 FIT in 10 billion hours.
