LOS ANGELES -- Opnext, Inc. (NASDAQ: OPXT), a global leader in high speed optical communications technology, today announced it will demonstrate its integrated Tunable TOSA during OFC/NFOEC (www.ofcnfoec.org), the industry's largest optical communications conference, being held March 8 -- 10 in Los Angeles. The demonstration will highlight automatic wavelength tuning designed to deliver stable wavelength control.

"Opnext's Tunable TOSA has been specifically designed to help customers reduce wavelength inventories and address their wavelength needs and time-to-market requirements," said Tadayuki Kanno, President of the Opnext module business unit. "Using our own, in-house designed Tunable TOSA, we're bringing the Opnext quality that our customers have come to expect in all our products."

Opnext's Tunable TOSA, developed in collaboration with Hitachi's Central Research Laboratory (CRL), is a hybrid design that combines the tunable laser and InP-MZ (Mach Zehnder) chips to offer optical shutter functionality. The Tunable TOSA delivers system performance to address mode-hopping for optimized wavelength stability in a variety of DWDM applications. In addition, the Tunable TOSA design will flexibly support negative chirp or zero-chirp DWDM applications to replace DWDM-XFP or 300-pin tunable transponders.
