Fiber topologies – a clear conduit to future networking Fiber topologies – a clear conduit to future networking Buying bandwidth with fiber Fiber networking: Variations on a theme Alcatel-Lucent Alcatel-Lucent believes a flexible fiber platform that is capable of many types of PON architectures is more advantageous than one that addresses a single architecture. The flexibility to also offer EPON, 10G EPON, GPON, 10G GPON and point-to-point services makes more sense for longer-term service needs. The ability to host residential, business and mobile backhaul services from a single architecture will become critical as the service provider needs to offer more types of services with the lowest total cost of ownership. Arris The Arris Optical Evolution architecture takes advantage of wavelength planning to minimize the need for new fiber construction and allow fiber repurposing for commercial services. All services are delivered over minimum fiber count – even a single fiber, where practical. A full-spectrum multi-wavelength architecture simplifies setup; there are more than 40 wavelengths per fiber. The system offers bidirectional transmission and reaches to 80 km and beyond. It is based on a modu- lar CHP platform and has CorView management. Aurora Networks Aurora Networks’ nodes are access platforms optimized for scaling bandwidth to each subscrib- er, while matching service-level requirements and supporting multiple segmentation technologies (LcWDM, DWDM, CWDM). For the upstream, Aurora offers its digital return solution, providing the performance required for full DOCSIS 3.0 deployments and supporting up to 80 return segments on just one fiber. Its Fiber Deep architecture is designed to provide high capacity per subscriber; operators can also benefit from the reduced operating costs associated with this architecture. The company’s fiber portfolio spans xWDM technologies supporting future CCAP rollouts, Fiber On Demand for dedicated Ethernet services for businesses and high-demand users, a BitCoax tool to boost coax capacity, RFoG and RFPON (RFoG plus PON) implementation, and a Node PON solu- tion for the migration to all-IP. CommScope CommScope aims to be a one-stop shop for optical networking with its BrightPath Optical Solution (BOS). The company’s optical portfolio includes headend, outside plant and end- user equipment, with different solutions designed for residential, MDU, commercial and cellular backhaul applications. BOS offers a choice of physical architectures, such as tapped, distributed or centralized splits. Complementing CommScope’s complete family of fiber-optic cables, splitters/taps and enclosures is a broad set of multi-wavelength transmitters, EDFAs, low-noise return path receivers and RFoG ONUs to enable operators to migrate to deep fiber infrastructures. Harmonic Many existing OTNs and hubs were built before the proliferation of narrowcast services and were not sized to support current equipment needs. Harmonic’s flexible fiber architecture uses the latest in 16-wavelength full-band SupraLink transmitter and Outdoor Hub technology to minimize operating expenses by consolidating and eliminating OTNs and hubs. The new Pwr- Blazer Outdoor Hub, based on Harmonic’s HLN3144 node, includes node-based optical switches for primary and secondary path switching, high-power EDFAs, and simplified fiber management. Combined with a small 4 x 4 segmentable node from Harmonic, operators can cost-effectively deliver the full range of residential and commercial services. Motorola Motorola’s fiber portfolio includes RFoG and GPON. The RFoG portfolio includes high-perfor- mance optical transmitters, optical amplifiers, both high-sensitivity and high-density optical re- turn receivers, modular optical nodes that can serve both RFoG and HFC serving areas from the same unit, and a full suite of optical network units to optimize cost and features. The company’s RFoG solutions enable a PON solution to be overlaid to provide IP video and next-generation Internet services. Motorola’s GPON solutions offer innovations such as indoor/outdoor ONTs with 802.11n Wi-Fi and with integrated battery backup and SCTE 51, supporting RF overlay applications; extended-reach PON architectures; interoperability; and higher-capacity, next-gen PON solutions.

Hybrid fi ber-coax technology has served the cable industry well for going on two decades, and HFC networks will remain viable for years to come, in large part because HFC was designed with the understanding that one day, network operators would want to extend the fi ber element of the network closer to customers’ homes and businesses – perhaps all the way there. So HFC networks have extensibility designed in.

In recent years, the combination of the growing need for bandwidth and the lowering cost of optical networking technology have made extending HFC networks a practical consideration.

Of course, there are options. One way to categorize those options is to group them into options for extending the HFC network to serve a proscribed area – these include node segmentation and Fiber Deep (also known by other names) – and options explicitly designed for a system-wide migra-tion to all-fi ber – including radio frequency over glass (RFoG), as well as either a gradual or direct migration to passive optical net-works (PON).

Which option is best will al-ways require a careful analysis of business needs against resources available. One such is included to the right, measuring the cost-ef-fectiveness of Fiber Deep against RFoG.
