CyOptics unveils high temperature uncooled laser

July 2, 2003
2 July 2003 Waltham, MA Lightwave -- CyOptics Inc., developer of Indium Phosphide (InP)-based optical components, recently announced the availability of its 2.5-Gbit/sec uncooled 1.55-um DFB laser with an operating temperature range of -20 ° C to +95 ° C. Part of the "1.5UDFB-C2551B000X" series, the new laser is ideal for metro networks and other applications requiring span lengths up to 100 km.

2 July 2003 Waltham, MA Lightwave -- CyOptics Inc., developer of Indium Phosphide (InP)-based optical components, recently announced the availability of its 2.5-Gbit/sec uncooled 1.55-um DFB laser with an operating temperature range of -20 ° C to +95 ° C. Part of the "1.5UDFB-C2551B000X" series, the new laser is ideal for metro networks and other applications requiring span lengths up to 100 km.

"The 1.5UDFB product was conceived through dialog with major component and system OEMs," explains Dr. Robert Hartman, vice president, device design and development for CyOptics Inc. "With the availability of the 1.5UDFB we are enabling new applications in the uncooled market that did not previously exist and at a cost structure advantageous for systems designers and service providers."

Currently available 1.5-um DFB uncooled sources are limited in operating temperature from 0 ° C to 70 ° C, requiring costly cooling to accommodate higher operating temperatures. The CyOptics laser, by contrast, features an operating temperature range of -20 ° C to +95 ° C. In addition, the CyOptics 1.5UDFB solves the interoperability problem that exists between longer reach 1.55-um and shorter reach 1.3-um applications by providing a single solution without costly cooling.

The 1.5UDFB enables transmission over 100-km of fiber without amplification and with less than 2-db dispersion penalty. It is packaged in an industry standard TO-CAN. Pricing is under $200 per unit in volume. Customer samples are scheduled to be available in September, and volume production is expected to begin within the fourth quarter of 2003.
