Cisco has been the predominant leader on cable access and DOCSIS technologies, including analog and digital optics, CMTS and CCAP solutions. Upgradeable with built in intelligence and simplified migration tools, the Cisco GS7000 Nodes deliver the insight and control to meet your networking needs.

CommScope Logo

CommScope 1.2 GHz NC-series and OM-series optical nodes support full DOCSIS® 3.1 capability and facilitate the upstream expansion to 204 MHz. Optimized for today's fiber deep and segmented HFC networks, they also support migration to and deployment of DAA and PON advanced network architectures.

Node Service Cables

Node Service Cables

Cable Assemblies link optical transport cable to optical processing equipment. This connection is critical and requires an environmental seal between the cable and the node feed-thru. Our node cables utilize a unique IP68 rated stainless steel feed-thru adapter, featuring an anti-twist coupling body and an optional anti-rotating nut. Our standard node assemblies use either a dielectric outside plant (OSP) cable or an armored OSP cable. Their multiple O-rings ensure a fully sealed cable and node. 

Digicomm stocks Node Service (entry) Cables of various lengths, numbers of fibers, and different optical connectors. In the rare occurrence that we do not already have the exact cable that you need, our engineers can work with you to design and build a custom Node Service Cable to meet your needs.
