Cisco Digital Reverse

High-Performance, Digital Reverse Technology

The Scientific Atlanta Prisma II Baseband Digital Reverse (BDR) System is tailor-made to help meet video-on-demand (VoD) and reverse-path traffic consolidation challenges. High-performance BDR technology provides the following benefits:

  • Modular and cost- effective
  • Easy to install and maintain
  • Space-saving, high-density platform enables 12-bit encoding and advanced digital signal processing
  • Supports return path transmission of analog video and high-order digital modulation signals such as 16- 24- or 264-QAM

These features come together to provide over 96 potential reverse buses on one fiber using high-power 1550 ITU 7dBm lasers for over 100km reach! Time division multiplexing at the transmission end allows approximately four times the reverse bandwidth capacity for data and voice applications.
