Fibera 50GHz Multi-Channel Wavelength Locker Secures

Telcordia Qualification for Optical Component Reliability

Fibera, Inc., a provider of innovative wavelength stabilization and management solutions, today announced that it has achieved a major milestone representing both an acknowledgement of the company's engineering excellence and a boost for the marketability of one of the company's principal products.

The Fibera 50GHz Multi-Channel Wavelength Locker (MCWL MCWL Merry Christmas with Love (song)

) has passed the stringent series of reliability tests needed to achieve Telcordia(TM) (formerly Bellcore(TM)) Group Requirements (GR)-1221-CORE certification for passive optical components.

The 50GHz MCWL is part of a product series that also includes 100GHz and 25GHz units, as well as non-standard units customized to individual user specification. Because all members of the Fibera MCWL series are athermal, there is no need for temperature control or compensation. All are ideal for laser wavelength stabilization and wavelength management in dense wavelength division multiplexing See WDM.  (DWDM (Dense WDM) The term given to wavelength division multiplexing (WDM) when significantly more channels were being added. Since WDM is increasingly more "dense" all the time, both terms are used synonymously. See WDM.

) wavelength transmitters, routers and ADD/DROP applications.

In DWDM optical communication systems, channel spacing The amount of bandwidth allotted to each channel in a communications system that transmits multiple frequencies such as fiber optics. It is measured as the spacing between center frequencies (or wavelengths) of adjacent channels. See guard band.  in GHz is typically 100, 50 and 25 as specified by the International Telecommunications Union See ITU.

(body, standard) International Telecommunications Union - (ITU) ITU-T, the telecommunication standardisation sector of ITU, is responsible for making technical recommendations about telephone and data (including fax) communications systems for PTTs and suppliers.
 (ITU (International Telecommunication Union, Geneva, Switzerland, www.itu.ch) A telecommunications standards body that is under the auspices of the United Nations. Comprising more than 185 member countries, the ITU sets standards for global telecom networks. ). To keep these channels from interfering with each other, the individual laser frequencies must be kept under strict regulation. Typically, a wavelength locker is used to stabilize the individual laser frequencies.

To meet Telcordia criteria, the Fibera 50GHz unit was required to pass a number of tests, including damp heat, repetitive temperature cycling, mechanical shock and vibration, and thermal aging that are conducted to accelerate the adverse effects of harsh environments on the component's lifetime. The achievement is significant because Telcordia GR-1221 is an internationally recognized, objective, third-party validation of the industry's highest level of reliability.

"Fibera has joined a select group of component manufacturers that have qualified as having met the rigorous mechanical and environmental protocols specified by Telcordia for optical component reliability," said John Tsai, president, Fibera, Inc. "This places Fibera in the upper echelon of optical component manufacturers and positions us very well to become a major supplier to companies that are shaping the new telecommunications infrastructure."

"During field trials, DWDM lasers stabilized with a Fibera locker achieved stability that exceeded lasers using lockers from other companies by a factor of two," said David Wang, vice president, Fibera, Inc. "Validation of reliability provided by Telcordia certification combined with our product's unparalleled performance will give network architects the confidence to include our 50GHz MCWL in current systems and to design it into future systems."

About the Fibera MCWL Series

Fibera's 50GHz Multi-channel Wavelength Locker (MCWL) was introduced in late 2001. Telcordia certification was secured in eight months. Information on the Telcordia certification is available from Fibera upon request. The MCWL product is available for volume shipment.

The Fibera MCWL Series consists of compact, high-accuracy, etalon-based Fabry-Perot wavelength stabilizers that provide outstanding thermal stability without temperature monitoring and compensation components. Each model in the series aligns to ITU grid with great accuracy, enabling operating points to be set to ITU grid with the exceptional precision of +/- 0.8 GHz. This remarkable ITU alignment accuracy avoids the need for electrical balancing other than the optical diode (PD) signal at ITU, thereby simplifying assembly, calibration calibration /cal·i·bra·tion/ (kal?i-bra´shun) determination of the accuracy of an instrument, usually by measurement of its variation from a standard, to ascertain necessary correction factors.  and field replacement.
