RFMD expands broadband portfolio for hybrid fiber coax networks

At this week’s SCTE Cable-Tec Expo in New Orleans (20–22 October), RF Micro Devices Inc is announcing the expansion of its broadband product portfolio, targeting hybrid fiber coax (HFC) transmission network hardware, cable head-end, cable hub equipment, and multi-dwelling unit/multiple tenant unit (MDU/MTU) equipment.

RFMD says that the new products enhance cable operators' network performance and enable increased bandwidth to support rapidly growing digital-centric services, such as HDTV, 3D HDTV and ‘mid-split’ DOCSIS networking.

The use of mid-split architectures can expand the amount of usable upstream or return-path bandwidth by more than 160MHz. For example, a mid-split capable HFC network can provide cable subscribers with Internet upload data rates that are five times faster than typical North American DOCSIS capable cable HFC networks. This enables multiple service operators (MSOs) to scale the data services on their existing cable transmission infrastructure, while delivering an enhanced Internet user experience and expanded digital services (e.g. HDTV streaming, HDTV downloads at ten times real-time data rates) to cable subscribers.

RFMD’s new HFC RF components include a broad selection of amplifiers and wide-bandwidth passive components. The amplifiers include linear amplifiers, low-noise amplifiers and return-path amplifiers. The passive components include couplers, two-way splitters and transformers.

RFMD says that, as it extends its product and technology range in broadband components, leading cable network equipment OEMs are increasingly selecting its HFC RF components for their performance, reduced power consumption and enhanced user experience.

Copies of RFMD’s 2010 Wired Broadband Product Selection Guide are available at the SCTE Cable-Tec Expo.
