Bringing Your Hub Further into Your Fiber-Deep HFC Plant — The trend will be
to move as much fiber-support components into the nodes or node locations
to further enable the fiber deep architectures

MSOs are migrating to architectures that require deeper and deeper fiber reach; bringing
fiber closer and closer to the home. Fiber distances and the need for better fiber utilization
will increase. Higher power transmitters and optical amplifiers will be needed to
accommodate new distances. To minimize the need for new fiber installations, better fiber
utilization (via multiplexer/demultiplexer, couplers/splitters, switches) and improved fiber
management will be required. The challenge will be to minimize the amount of capital
expenditure, yet have all the required optical components to further enable and optimize
this new system.

Fiber management and fiber coupling (mux/demux, etc.) are typically done at the
headend or hub, or within strand-mounted splice enclosures. With the Cisco GS7000
Optical Node/Hub solution, this can now be done at the hub node.

Optical amplification is typically done at the headend or hub, or with strand-mounted
optical amplifiers. This can now be done in the hub node.
•
The ability to add redundancy, or enable network switching for survivability, is typically
done at the headend or hub. This can now be done in the hub node.
To efficiently manage this new architecture, MSOs will need to expand their fiber plant
further and further into their networks, and they are going to need the tools like those in the
headend or hub to effectively enable it.

The Cisco
®
GS7000 platform provides operators with a future-flexible foundation to take
fiber deeper and is scalable to expand as services and customer demand expand. Cable
operators can deploy our standard 4x4 industry-leading GS7000 optical node, and when
ready, deploy fiber deeper into the hybrid fiber coax (HFC) network, taking the first step
toward optical hub migration through the addition of optical amplifiers and/or optical switch
modules.
