Transponders are used to convert an optical signal to match the frequency and optical transmission requirements of a DWDM network and typically service providers require a different transponder for each different transmission speed. Ditech's Palette Multi-Rate Transponder enables service providers to transport various data transmission rates (155 Mbps, 622 Mbps, 1.25 Gbps, 2.5 Gbps) without swapping out transponders. This shortens provisioning time, eliminates network down-time, and reduces network equipment costs as service providers replace the functionality of four transponders with a single Ditech Multi-Rate Transponder. Ditech's Palette Transponder family also can be used to extend the usefulness and reach of non-DWDM legacy equipment (such as SONET/SDH transmission equipment and IP routers) by converting 1310 nanometer (nm) optical signals to the 1550 nm range. Once converted to the 1550 range, service providers can extend the reach of legacy optical equipment by hundreds of miles using Erbium Doped Fiber optical amplifiers (such as Ditech's Star series), which operate in the 1550 range. Ditech's Palette Transponder family is scheduled to be available in October 2000, and the list price for the products are: 155 Mbps Transponder -- $8,750; 622 Mbps Transponder -- $9,250, and Multi-Rate Transponder -- $11,500. "Our Palette Transponders provide a flexible, cost-effective subsystem for building next generation networks and extending the reach of legacy optical networks," said Tim Montgomery, Ditech's President and CEO. "Next generation optical networks need to establish high-bandwidth connections on the fly, and our Multi-Rate Transponder is a key subsystem in providing this software- programmable functionality. Our Palette Transponder family also helps to extend the usefulness and reach of a vast installed base of SONET, SDH, and IP router networks." Ditech Communications Corporation Ditech Communications Corporation is a global telecommunications equipment supplier for voice and data networks. Ditech's voice products are high- capacity echo cancellers that utilize advanced software and digital signal processor (DSP) technology. This unique combination of software and hardware allows Ditech to deliver Voice Quality of Service (VQoS(TM)), a robust and cost-effective solution for voice enhancement and echo cancellation. Ditech's products for data networks provide building blocks for high-speed, high- capacity optical backbone networks. These products are based on wavelength division multiplexing (WDM), a technology that enables many wavelengths of light, each carrying multiple gigabits of information, to be carried on one fiber optic connection. With Ditech's optical subsystem products, network equipment companies and service providers can quickly and cost-effectively expand their network capacity to meet the growing demands of the Internet age.
