The Cisco EDR 85 System includes EDR Transmitter modules that
install in GainMaker and GS7000 Nodes, and companion Cisco
Prisma® high-density (HD) EDR PRX85 Receiver modules that install
in a Prisma II or Prisma II XD chassis at the headend or hub. The
transmitter and receiver use Small Form Factor Pluggable (SFP) optical
pluggable modules (OPMs) for enhanced flexibility. The Cisco EDR 85
System operates over the 5-85 MHz range and supports all standard
reverse frequency bandwidths at 40, 42, 55, 65, and 85 MHz.
