4 fibers per node (i.e., 2 fibers each dedicated to routing signals from both directions to each nodefor route diversity), plus 12 fibers threaded through all nodes.

Cox Communications’ “ring-in-ring” fi ber architecture in-cludes fi ber route diversity and optical electronic redundancy to each node serving area providing uninterrupted video, voice, data and commercial services. Many MSOs have diverse-ly routed fi ber to critical commercial customers; Cox’s success in the commercial marketplace led to the decision to provide commercial-grade reliability to all customers. As a result, the company has virtually eliminated large fi ber outages. Cox’s “ring-in-ring” design is created by routing a fi ber cable sheath into the community through a number of node serving areas and returning to the point of origin to close the path. This process is repeated until all node serving areas are ringed, taking advantage of previous routes to minimize con-struction costs. Each ringed sheath contains fi bers dedicated to each node serving area, fi bers for future nodes and a num-ber of commercial threaded fi bers based upon the business potential along the ring path. Commercial threaded fi bers sometimes called “metro fi bers” are used to deliver fi ber-based services to schools and businesses along the ring using the most cost-effective transport. Commitment to ringed fi ber routes requires good capacity planning as a community grows and creative techniques for controlling construction costs, but the results are well worth the effort.

Optical access via Gigabit Passive Optical Networking (2.4 GB upstream and 1.2 GB downstream per GPON) provides the foundation for the delivery of advanced Ultra-Broadband services today and in the future. An end-to-end optical access architecture hosts the optical line terminal (OLT) and various types of optical net-work terminals (ONT) that support service delivery and provide connectivity to the subscriber end point. The OLT is the system hub that aggregates services both to/from the network and to/from the access network and subscriber. ONTs are intelligent devices supporting embedded services such as SIP/H.248 clients, IGMP multi-casting and direct software upgrades, and are designed to connect single family, small business and multi-dwelling living units to multi-services. Available ONTs support Motorola-Aloha return path, MoCA and HPNA home networking technologies to support a wide range of set-top box (QAM, QAM/IP and IPTV) technolo-gies. The optical access architecture also includes interfaces providing North-bound linkage to quality TDM or IP voice services via integrated voice gateways, broadcast and on-demand IP video and very high-throughput data services. Scalable and reliable system software with advanced access to business and operational support systems (such as XML interfaces) and a robust EMS are the most important features of any end-to-end optical access system. Of importance here will be the ability to rapidly provision services, manage problems and drive down operational costs by incorporating easily managed business tools.

Alloptic’s RFoG solution provides MSOs with the ability to upgrade their distribution network to a seamless fi ber optic infrastructure from the headend to the subscriber while maintaining their current processes, procedures, headend and subscriber equipment. Core to Alloptic’s RFoG solution is the MicroNode, which provides HFC node functionality at the subscriber location, eliminating the costs associated with maintaining and operating today’s HFC nodes and repeaters. The company’s RFoG solution also provides a seamless migration path to supporting a Passive Optical Network (PON) solution co-resident on the RFoG network; thus, supporting business services with an ultra-high bandwidth solution.

FTTH made simple. CommScope’s BrightPath is an inno-vative FTTx distribution system designed to work seamlessly with existing hybrid fi ber/coax (HFC) networks. BrightPath is fully compatible with existing headend and subscriber equipment, allowing operators to cost-effectively deliver their current suite of analog, digital and interactive services all over fi ber-to-the-home. This system can be deployed selectively as required to provide a competitive advantage, with lower upfront cost and maintenance relative to tra-ditional passive optical networks (PONs). The BrightPath architecture is a unique, all-optical distributed tap design that mirrors HFC in design and improves performance capability at a comparable cost. It allows an operator to deploy FTTH yet maintain the same back offi ce support, CMTS, subscriber equipment and services. Once installed, if business cases for advanced services are identifi ed, the fi ber infrastructure of BrightPath can be easily adopted to sup-port wavelength services using known WDM technologies.

Harmonic’s scalable WDM architecture

Harmonic’s Network Solutions for Advanced Services Harmonic’s fl exible fi ber architecture uses the latest in WDM (wave division multiplex-ing) technology to leverage the existing outside plant, minimize operating expenses, and deliver a full range of residential and commercial services. Harmonic’s MAXLink Plus 1550 nm transport system enables headend consolidation over distances of 300 km or more, reducing the operating costs of secondary or remote headends while allowing operators to get the most out of their capital equipment budgets. The complete lineup of broadcast television is transmitted over the video backbone to each hub using Har-monic’s MAXLink 1550 nm solution. Data, VoIP and VOD content are carried on DWDM wavelengths from the headend to hubs using Harmonic’s METROLink DWDM transmit-ter. In the last mile, Harmonic’s PWRLink 1310 nm and METROLink DWDM transmitters effi ciently deliver the full range of content and services to PWRBlazer nodes. Nodes deeper in the network can also be reached without the need for costly instal-lation of fi ber between the hub and the primary node. Four-way segmentation for both the forward and the return transmission is achievable with the scalable PWRBlazer nodes. This is achieved using Harmonic’s full range of dedicated analog and digital re-turn path transmitters that are based on CWDM and DWDM technology, including a 65 MHz digital solution. The high output power node is also very well adapted for extreme-ly deep deployments such as node-plus-zero or node-plus-one architectures. In addition, Harmonic’s FLXLink Commercial Services Solution is ideal for providing high-speed network access and managed services to commercial entities for a variety of applications, including cell tower backhaul.

Enablence’s Trident7 Universal Access Platform enables standards-based delivery of complete triple-play voice, data, and video services, including the market’s only integrated RF return solution, over a single fi ber outside plant distribution. The Trident7 solution includes the Trident7 OLT, Compact OLT (COLT), and a diverse selection of ONTs to address the distribution and customer access portions of the net-work. Completing the Trident7 portfolio is an open standard management solution consisting of a full-featured element management system integrated with fl ow-through provisioning, billing and inventory features (OSS), and customer care applications. The Trident7 solution includes one or more Trident7 OLTs or COLTs in the headend or distributed in the fi eld, the passive optical splitter/coupler com-ponents within the FTTP distribution network, and the ONTs at subscriber locations. A system headend typically serves as the demarcation point between services and the FTTP network, thereby providing a central location to aggregate and manage the handoff of services. This solution offers the most fl exible deployment options, whereby all voice, video, and data traffi c may originate from a single central offi ce. The modular architecture of the Trident7 solution enables incremental upgrades to network capacity without a costly reconfi guration of the physical optical network. A minimum confi guration requires a single 10 Gigabit or Gigabit Ethernet connection and a single PON module. Additional 10 Gigabit or Gigabit Ethernet connections and PON modules may be added without disrupting the network, thereby enabling network operators to provision their networks to support either 100 percent capacity from day one or a success-based pay-as-you-grow model that scales deployment with subscriber penetration.
