The Cisco® Enhanced Digital Return (EDR) 85 System expands the functionality of Compact Segmentable Nodes by increasing the performance, reach, and efficiency of the reverse path transmissions.
The Cisco EDR 85 System includes EDR Compact Segmentable Node A9020x Transmitter modules that install in the node, and companion 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 SFP (Small Form Factor Pluggable) style 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.
