TranSwitch and TeraOp -USA- Inc. Announce Sampling of TVA-A and TVA-B Series VOAs for Metro Optical Networks at ITU Telecom World 2003.


Business Editors

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.  TELECOM WORLD 2003

SHELTON, Conn.--(BUSINESS WIRE)--Oct. 9, 2003

New TVA-C Series VOAs for multi-channel high density WDM (1) (Wavelength Division Multiplexing) A technology that uses multiple lasers and transmits several wavelengths of light (lambdas) simultaneously over a single optical fiber.  to launch

TVA-A and TVA-B Series VOAs are direct replacements for existing VOAs in legacy optical transmission equipment. TeraOp VOAs are the first off-the-shelf optical communications products that deliver high quality at competitive prices based on the company's patent-pending MEMS (MicroElectroMechanical Systems) Tiny mechanical devices that are built onto semiconductor chips and are measured in micrometers. In the research labs since the 1980s, MEMS devices began to materialize as commercial products in the mid-1990s.  technology.

TVA-A VOAs are ideal for use in wavelength multiplexers, Optical Add/Drop Multiplexers (OADMs), and optical amplifiers. They can be packaged as a single channel or in an array of up to 40 channels as required by the customer. TVA-B VOAs are targeted specifically to the new generation of optical modules integrated with optical filters, especially filters based on Thin Film Filter (TFF TFF The Final Frontier (Star Trek movie)

) technology.

The TeraOp VOAs' patent-pending MEMS actuator enables very low temperature-dependent loss (TDL TDL Tokyo Disneyland

 and operating temperatures. The actuator also provides a linear control voltage-vs.-attenuation characteristic. This is a major breakthrough compared to many competitive devices, which exhibit an exponential characteristic. In addition the TeraOp MEMS design includes provision for damping control, which ensures fast settling time without the "ringing" typical of competing devices. Since the introduction of the TVA-A and TVA-B Series in June, leading optical communications equipment and systems manufacturers have expressed significant interest and have received product information and samples for evaluation.

Along with the sampling of the TVA-A and TVA-B products, TeraOp is also introducing its new TVA-C Series VOAs. The TVA-C Series simplifies device integration and packaging for customers by providing all fiber connections on one side of the VOA (Variable Optical Attenuator) A device that can incrementally adjust the power of the optical signal passing through it. . The first device in this series is an 8-channel array using an industry-standard small package, offering both transparent (normally open) and opaque (normally closed) VOAs. The TVA-C Series uses the same proven single-layer concept and MEMS technology as the previous devices to ensure high quality at very competitive prices. The new VOA array is ideally suited for multi-channel high density WDM equipment and benefits OEMs by saving board space and dramatically decreasing the cost per port.

The TVA-A, TVA-B and TVA-C Series VOAs offer optical equipment manufacturers extremely compact size, form factor, and cost advantages as well as ease of integration with optical switches. TeraOp has responded to the growing market need for integrating discrete optical components with a family of VOA products that simplify system design and improve performance while reducing cost per port. This significantly benefits equipment vendors by freeing up critical resources for system development instead of integration of components.

Customers can learn more about TeraOp TVA-A, TVA-B, and TVA-C Series VOAs in the TranSwitch booth at the USA Pavilion, Stand 1230.225, at ITU Telecom 2003 in Geneva October 12-18.
