Redfern Integrated Optics, Inc. (RIO) to Demonstrate World’s First 10Gbps 40km and 80km DWDM TOSA in proposed SFP+MSA Transceiver Module at OFC/NFOEC 200

Ground-Breaking Laser Technology on Display for Industry-at-Large

Anaheim, Calif. - March 6, 2006 -Redfern Integrated Optics, Inc. (RIO), a developer and manufacturer of low-cost, high-performance optical transmitters for telecommunications, data transmission and other markets, today announced that it will offer a live demonstration of its revolutionary technology this week at the 2006 OFC/NFOEC show in Anaheim, Calif.  In booth #2373, RIO will showcase its directly-modulated 10Gbps External Cavity Laser (ECL) transmitter optical sub-assembly (TOSA) for long reach, 40km and 80km DWDM, in an SFP+ form factor transceiver module.

The SFP+ transceiver module consists of RIO’s 10Gbps 1550nm ECL TOSA and an AGC PIN/TIA receiver with linear output which allows the host based equalization for fiber impairments as well as longer PCB trace.  The compactness and low power consumption of RIO’s TOSA enables such a small form factor transceiver to operate at 10Gbps up to 80km in both TDM and DWDM applications.
“RIO maintains a strong commitment to providing superior cost-effective, high-performance and reliable solutions to meet the small size, low power consumption, high optical power, and low cost requirements of the optical communications industry,” said Radu Barsan, president and CEO of RIO.  “We’re excited to display RIO’s leadership in innovation within the industry arena of OFC/NFOEC 2006.”

RIO has developed the world's first 10Gbps 1550nm directly-modulated ECL TOSA for use in XFP, X2/XPAK, XENPAK and the upcoming SFP+ MSA transceiver module. The cavity design is based on RIO's proprietary PLANEX technology, consisting of a planar waveguide with integrated Bragg reflector and low cost high-speed gain chip. The ECL provides a narrow spectrum with negative chirp, resulting in 80km reach and beyond, and high output power and wavelength stability sufficient for 50GHz DWDM application without the use of a wavelength locker. 

RIO is collaborating with Broadcom Corporation to jointly promote the upcoming SFP+ MSA for 10Gigabit applications.  “XFI technology and the XFP module represent a quantum leap in the evolution of 10Gbps transceivers,” said Ali Ghiasi, senior principal scientist for Broadcom Corporation. “We’re encouraged with RIO’s ability to effectively enable SFP+ to perform at 10Gbps for extended reach applications with its smaller size, lower power dissipation and lower cost – ultimately completing the evolution.”
