NASHUA, N.H., April 17 -- TeraConnect reports that it has demonstrated the world's densest optical interconnect. Over the course of the eight-week proof-of-concept demonstration with a major manufacturer of network servers, TeraConnect said that it replaced the company's copper-based interconnects with a massively parallel, VCSEL-based optical transceiver module connecting 640 active optical devices. "In actual performance during the test, the optical transceiver from TeraConnect never failed as it passed data over an extended I/O link on the high-end server. High reliability and scalability are critical for moving forward with this technology," said Glenn Thoren, TeraConnect's vice president of business development. TeraConnect has designed its two-dimensional fiber optic device to lessen power consumption and reduce transceiver costs otherwise incurred by the need for extra interfaces, components and packaging.
