Enhanced Digital Return System Overview

Features
The EDR Enhanced Digital Return 1:1 and 2:1 Multiplexing Systems have the
following features.
High-performance Digital Return technology
12 bit encoding enables transmission of analog video in the reverse band
High-order digital modulation signals (e.g.,16 QAM, 64 QAM, and 256
QAM)
Multiple operating modes in the EDR receiver support EDR transmitter
Optical Pluggable Modules (OPM) enable flexible inventory management
Long reach transmission capabilities eliminate the need for optical amplifiers,
reducing cost and space requirements
Capable of sending 80 individual 5 – 85 MHz reverse signals over a single fiber
Compatible with Cisco's 40 wavelength DWDM system
Enables independent balancing of reverse traffic at EDR receiver RF ports
Simplified setup reduces installation time and expertise requirements
Distance- and temperature-independent link performance simplifies
engineering and maintenance requirements
Space-saving, high-density deployment in Prisma II or Prisma II XD chassis
increases deployment cost-efficiency
Optional monitoring of node (GS7000) and Tx (GS7000 and GainMaker)
parameters available at the receiver
The EDR 2:1 Enhanced Digital Return Multiplexing System leverages 2:1
multiplexing to reduce fiber usage.
