New Reverse Power Feed Technology is a Critical Technology for Affordable FTTdp and G.fast Deployments in Communications-based Solutions
ALISO VIEJO, Calif. - Microsemi Corporation (Nasdaq: MSCC), a leading provider of semiconductor solutions differentiated by power, security, reliability and performance, today introduced at the Broadband World Forum (BBWF) 2014 its new reverse power feed (RPF) technology, a critical technology for FTTdp and G.fast deployments.
G.fast, the new xDSL standard for 1gbps over copper, has a maximum expected range of 250 meters (m). In order to achieve the highest data rates with G.fast, shorter loop lengths are required which leads to the need for fiber to the distribution point, or FTTdp. These fiber-fed distribution point units (DPUs) in some cases will require reverse power feed, either due to the location of the DPU, regulations of countries or economic reasons related to power grid hookup and monitoring the grid with a smart meter. See more information about the benefits of reverse power feed at http://www.microsemi.com/product-directory/ics/3551-reverse-power-feeding. RPF technology was developed with G.fast in mind, but is backwards compatible with VDSL2.
Microsemi's RPF for DSL applications demonstrated at BBWF, are designed to be used in conjunction with the VDSL2 and G.fast chipsets from Broadcom Corporation (Nasdaq: BRCM).
"We're excited to leverage our expertise in both DSL and remote powering applications to expand Microsemi's portfolio in the broadband market in collaboration with Broadcom," said Iris Shuker, director of product line management at Microsemi. "PD81001 RPF PSE used in the CPE paired with PD70101 RPF PD used in the DPU are based on mature technology which is being standardized in ETSI and BBF, and enables fast deployment of advanced DSL technologies with reverse power feed. Our solution is based on a metallic-signature handshake protocol and provides Broadcom's DSL devices with inherent reliability and cost advantages over more complex communication based solutions."
"Broadcom is enabling advanced DSL broadband solutions with data rates that can reach 1 Gigabit per second," said Jim McKeon, senior director of product marketing, Broadband Carrier Access at Broadcom. "Microsemi's new RPF solutions simplify the deployment of FTTdp, allowing operators to reduce CAPEX and in turn foster the development of even more cost-effective DSL solutions."
