Harmonic’s flexible fiber architecture uses the latest in WDM (wave division multiplexing) 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 Harmonic’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 transmitter.

In the last mile, Harmonic’s SUPRALink 1550 nm, PWRLink 1310 nm and METROLink DWDM transmitters efficiently deliver the full range of content and services to PWRBlazer nodes. The recently introduced SUPRALink line of products can carry 1 GHz of full-band analog and digital content per wavelength over 40 km, allowing deeper deployment of optical nodes and minimizing the expense of deploying more fiber. SUPRALink is scalable to eight wavelengths in one-wavelength increments without sacrificing fiber distance, providing system operators with a ”pay-as-you-grow“ solution that can accommodate their evolving needs for more network capacity.

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 return 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 extremely deep deployments such as node-plus-zero or node-plus-one architectures. In addition, Harmonic’s MAXLink forward path transmitters and return path receivers can be used in a cost-effective RF over glass (RFoG) architecture for greenfield-type deployments, en-abling cable operators to provide a competitive and reliable fiber-to-the-home solution.

The industry’s first RFoG-Ethernet access network

CMTS& STBcontrol

Alloptic blends the worlds of passive optical networking (PON) and RF over Glass (RFoG) technologies to create a unique hybrid RFoG-PON solution. This access network solution provides flexibility with POTS and VoIP telephony, commercial-quality rich Ethernet services, native T1/E1 capabilities, and both RF and IP video. It also migrates to 10GbE PON services and is enabled for DOCSIS control. With market-leading RFoG technology and multiple ONTs optimized for business, MDU and residential applications, Alloptic delivers the access system-of-choice to network operators worldwide.

Optical access solutions such as fiber-to-the-home via PON or RF over Glass (RFoG) are being deployed by telco and cable operators throughout the world. Motorola’s FTTH portfolio consists of Gigabit Passive Optical Networking (GPON) solutions, as well as FTTH solutions known as RFoG, which are designed for use in cable networks where transparent delivery of RF video and DOCSIS-based service delivery is desired. For telco and cable operators, GPON provides a 2.48 GB upstream and 1.25 GB downstream throughput, and it is a point-to-multipoint technology serving up to 64 subscrib-ers via a single GPON connection back to the optical line terminal (OLT). An end-to-end optical access architecture hosts the OLT and various types of optical network terminals (ONTs) that support service delivery and provide connectivity to the subscriber end point. For cable operators, RFoG transparently bridges current RF video and DOCSIS-based services over an all-fiber network and future-proofs the access network by allowing parallel deployment of PON-based services and, at some future point, conversion to all-fiber, PON-based – such as GPON-based – services in the future.

Hitachi offers the widest selection of PON solutions of any vendor, including RFoG, advanced EPON-based DePON and MW-PON, and GPON products. This flexibility enables MSOs to implement an “incremental migration” approach, rolling out fiber-optic access in step with actual network revenue potential. Operators can deploy Hitachi’s RFoG or GPON solutions, or Hitachi’s Salira line of EPON/DePON/MW-PON, or any combination for triple-play, business services, mobile backhaul, wholesale interconnect and other advanced subscriber services.

BrightPath is an innovative fiber distribution system designed to work seamlessly with existing 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 fiber-to-the-home. This system can be de-ployed selectively as required to provide a competitive advantage, with lower upfront cost and maintenance relative to traditional passive optical networks (PON). The BrightPath architecture is a unique, distributed optical tap design that mirrors HFC in performance, design and cost. It allows an operator to deploy FTTH, yet maintain the same back office support, CMTS, subscriber equipment and services. Once installed, if business cases for advanced services are identified, the fiber infrastructure of BrightPath can be easily adopted to support wavelength services using known WDM technologies.
