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 powerful MAXLink 1550 nm solution. Data, VoIP and VOD content are carried on DWDM wavelengths from the headend to hubs using Harmonic’s GIGALight gigabit Ethernet transport solution. In the last mile, Harmonic’s PWRLink 1310 nm and METROLink DWDM transmitters efficiently deliver the full range of content and services to scalable PWRBlazer optical nodes. As demand increases, nodes can be segmented to support up to four service areas 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. 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.

Use of an RF video overlay is a cost-effective way for operators to significantly increase fiber capacity, and deliver video over a passive optical network (PON) or a switched Ethernet fiber-to-the-home (FTTH) network. The operator can provision the RF overlay for analog-only subscribers or send hundreds of simultaneous HD streams into each home. Bandwidth and switching requirements of the IP network are also significantly reduced as broadcast television services do not consume bandwidth allocated for data and voice services. A hybrid RF/IP set-top box can be used to give viewers a seamless experience of digital and/or analog broadcast video-over-RF as well as interactive video-over-IP.
