Mindspeed(R) and Sumitomo Electric Improve Cost and Simplicity of Deploying Fiber to the Home.

Sumitomo's Laser Interfaces with Mindspeed's Burst-Mode Laser Driver and Integrated Limiting Amplifier to Fully Leverage Mindspeed's EyeMinder[TM] Technology

NEWPORT BEACH, Calif. -- Mindspeed Technologies, Inc. (NASDAQ:MSPD), a leading supplier of semiconductor solutions for network infrastructure applications, today announced that it has collaborated with Sumitomo Electric Industries , Ltd. to demonstrate the advantages of Mindspeed's EyeMinder dual digital closed-loop technology in simplifying and cost-reducing fiber to the home (FTTH) deployments with an implementation featuring Sumitomo's laser with Mindspeed's M02090 burst-mode laser driver with limiting amplifier.

Sumitomo's SXT4240 laser is among the first optical lasers that customers can use to fully leverage Mindspeed's EyeMinder technology which monitors and compensates for laser aging and temperature effects. Sumitomo's lasers are used in its own bidirectional transceivers, diplexers and triplexers, as well as being supplied to other manufacturers. When used in conjunction with EyeMinder technology, the Sumitomo SXT4240 laser can operate over life and temperature with a constant extinction ratio and average optical power. Calibration can occur at any single temperature and, once the monitor photodiode targets are determined for the P0 and P1 levels, will then apply at all temperatures over the life of the device.

"We are pleased to be able to offer this important new benefit to our SXT4240 customers," said Eddie Tsumura, Vice President of Marketing at ExceLight Communications, a sales and marketing subsidiary of Sumitomo Electric. "By improving laser operation while lowering laser characterization time and expense, Mindspeed's EyeMinder technology will cut system costs for our customers."

"Sumitomo is one of the world's leading manufacturers of high-performance and high-reliability products for FTTH systems, and we are proud of their endorsement of our EyeMinder technology," said Hasnain Bajwa, Executive Director of Marketing for Mindspeed. "We are encouraged by the industry's adoption of EyeMinder technology to reduce system costs and help accelerate the deployment of FTTH passive optical networks."

Sumitomo's laser is incorporated into a number of optical devices including Sumitomo's own SXT4240-S/GP1 bidirectional diplexer, which is suitable for 2488 Mbps downstream/1244 Mbps upstream bidirectional transmission applications. A laser diode and a monitoring photodiode are mounted with a detector APD and a pre-amplifier into an integrated package with a single mode fiber pigtail.

Mindspeed's M02090 integrates a burst-mode laser driver with a limiting amplifier to deliver up to 2.5 Gbps data rates in optical network units/terminals (ONU/ONT) used in passive optical networks (PONs). The M02090's advanced EyeMinder technology reduces overall system costs by providing for the real-time monitoring of, and compensation for, laser aging and temperature effects in broadband PON (BPON), Gigabit Ethernet PON (GEPON) and gigabit PON (GPON) applications with a single, versatile solution.

An application note describing the implementation of the M02090 with EyeMinder technology combined with the Sumitomo SXT4240 laser is available on Mindspeed's web site at www.mindspeed.com.
