ADC Launches DWDM Digital Return Path Transmission System for the Global Marketplace ADC’s Leading-Edge Technology Drives Cost-Effective Next Generation System Designs MINNEAPOLIS – October 3, 2000 – ADC (Nasdaq: ADCT; www.adc.com) a leading global supplier of fiber optics, network equipment, software and integration services for broadband, multiservice networks, today announced the availability of the industry’s first 5–65 MHz DWDM 1550nm Digital Return Hub to Headend Transmission System for the Optiworx Ô Cable Transport Platform for the global marketplace. “The new system concentrates return traffic in the key hub to headend area where there is limited fiber available and bandwidth contention is a key operating concern. Combined with ADC’s leading-edge dynamic range extender circuit (DRC) technology (patent pending), this system offers savings in time and investment for system design and operations, “ said John Caezza vice president and general manager of ADC’s Broadband Communication Division. With the ability to transport two 5-65 MHz RF streams per transmitter on an ITU standard wavelength, and by combining 16 wavelengths on one fiber, this system can deliver 32 return paths from hub to headend. If the operator combines two 5-65 MHz streams from the node prior to input in the DWDM transmitter, 64 paths can be transported, saving critical bandwidth. ADC’s DRC technology minimizes the impact of noise leaking into the system and maximizes bit error rate (BER) performance with increased transmitter drive power. It also extends the dynamic operating range of normal digital transmitters by 12 dB by overcoming the typical RF signal overloading, or “cliff effect”, of normal analog/digital conversion. Digital technology provides link independent performance, which eliminates component degradation associated with analog system design, cost-effectively enabling system designs over geographically diverse areas up to 100km. “It’s the first step in migration towards next generation architecture deployment,” said Caezza. Transmitters and receivers are available in rack-mountable HWX modules.
