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.
