KT Corporation Deploys Marvell's Game Changing Technology for Fiber-to-the-Home (FTTH) Class Gigabit Broadband Services

Marvell partners with Ubiquouss in providing unprecedented access over existing copper infrastructure for Korea's largest broadband internet service provider

Barcelona and Santa Clara, California (February 25, 2014) – Marvell® (Nasdaq: MRVL), a worldwide leader in integrated silicon solutions, today announced that KT Corporation (KT), formerly known as Korea Telecom, the largest broadband internet service provider in Korea with 8 million broadband internet subscribers and 4 million IPTV subscribers, deploys the game changing Marvell technology through its equipment manufacturer partner Ubiquoss. KT Corporation and Ubiquoss have selected™ to enhance broadband access in multi-dwelling unit (MDU) buildings and enable FTTH class Gigabit broadband services for the Connected Home over KT’s existing copper infrastructure. KT and Ubiquoss are the newest to join a growing list of service providers, ODM and OEM partners implementing Marvell’s transceiver in their latest digital home and access products, accelerating global adoption and enlarging the scope of ITU-T technology.

“At Marvell we are very proud of our ingenuity and capability in delivering high performance and cost effective solutions to empower the global industry. This game-changing technology is our latest contribution in enabling major service providers like KT Corporation to provide superior broadband service with existing infrastructure,” said Weili Dai, President and Co-Founder of Marvell. “I would like to thank the hard working teams of Marvell, Ubiquoss, and KT for their close collaboration in making the first deployment possible. It is our passion and commitment to continue bringing great technologies to better the lives of global consumers.”

“After successful field trials during the second half of 2013 with Ubiquoss equipment based on Marvell technology, we have determined the technology has an impressive performance, is easier to deploy and provides substantial CAPEX savings when compared to traditional FTTH alternatives. We expect to extend the value-added service soon after the field’s evaluation to the major regions where demand is high for such advanced services,” said Dong Myeon Lee, CTO and Executive Vice President of Institute of Convergence Technology at KT Corporation.

“Ubiquoss is dedicated to deliver state-of-the-art networking solutions for the broadband access market,” said Yong Ho Choi, EVP of Marketing at Ubiquoss. “By designing Marvell’s silicon into our Gigabit Phoneline systems, we are giving a new life to the existing copper access infrastructure. technology enables us to provision both symmetric and asymmetric access services as needed, solving one of the key problems faced by fixed-line service providers in the past. This technology is field tested and available today from Ubiquoss.” enables fast and powerful connectivity, at data rates up to 1 Gbit/s over existing wiring, including electrical wires, coaxial cables, twisted pair and plastic optical fiber. is technology applied for wireline broadband access networks, as an upgrade to VDSL2. Marvell provides a much higher data rate (over 500Mbps over copper) than legacy VDSL systems (100 Mbps), TDD architecture with configurable uplink/downlink ratio, advanced FEC, automatic retransmission, NDIM technology for interference mitigation and automatic mitigation of Near-End Crosstalk (NEXT).

Ubiquoss’s powered and industry’s first products enable KT to deliver FTTH-class service to MDU apartments while avoiding the costs of replacing copper wires with optical fiber. These increased data rates ensure the access network is future-proof and ready to provide new services such as multi-stream 4K IPTV, cloud-based storage or 802.11ac wireless hotspots. With 18M national subscribers to wired broadband services (including xDSL, LAN and FFTH), KT has the world’s highest broadband penetration rate (97%) and is leading the broadband services revolution by continuously adopting next generation technologies for its population. Early 2013, the Korean government has announced its commitment to enable Gigabit broadband speeds in most parts of the country by 2017 in order to meet an explosive growth in data traffic. As the #1 wireline telco in Korea in market share, with 18M telephony subscribers (62%), 8M broadband subscribers (44%) and 4.7M IPTV subscribers (26%), KT has selected Marvell to be the pioneer in enabling the world’s first Gigabit broadband services for its subscribers today.
