Ethernity Networks Integrates 40G Carrier Ethernet Solution and Next Generation G.fast into DPU with 10G Channelized Ethernet Interfaces

OEM Customer Platform with ENET4840z 40G Flow Processor Supports Reverse Power Feeding

Oct 25 2017, – BBWF 2017, stand C110B, Berlin >  Ethernity Networks (AIM: ENET.L), an innovative technology solutions provider that develops network data processing technology used in high-end Carrier Ethernet applications across the telecom, mobile, security and data centre markets, announces integration of the field-proven ENET4840z/99 with NG G.fast technology to improve transmission over existing copper cabling and symmetrical Gigabit access.

The advancements, based on the latest ITU-T recommendations for NG G.fast, include 212 MHz spectrum and coordinated dynamic time allocation (cDTA), and together with the rich set of features and ultralow power requirements of 40G ENET48xx powerful flow processor platform make a winning combination for the market of residential and business communications. The extremely low power consumption of the solution is uniquely positioned for Reverse Power Feeding (RPF) deployments.

“From Ethernity’s perspective, smoothly supporting 212MHz is a very important transition,” said Eugene Zetserov, VP Product Marketing of Ethernity Networks. ”Ethernity adds the unbeatable small-form-factor and low power consumption to enable RPF option to the new solution that gives the broadband market long awaited extended access opportunities.”

“NG G.fast will bring a new wave of products and drive development of new technologies including different flavors of NGPON, and as a leader in broadband data path solutions, Ethernity is ready to support it all. The huge benefit to our customers is that FPGA solution enables us to add new functionalities without a new chip – smoothly supporting the new technology,” Zetserov added.

The integration doubles the upstream performance of G.fast solution for FTTx applications. Telecom operators will be able to run data over fiber to multi-dwelling units (MDUs/DPUs) or multi-tenant business sites, and use the existing site wiring for connecting individual customers. Extending Gigabit access services to individual customers in the fastest and most cost-effective way is a challenge in advanced markets of the US, Europe and Asia, where competition and subscribers churn are high.

NG G.fast technology answers the challenge, and to further reduce installation costs, RPF eliminates the need to provision infrastructure power to the DPU by syphoning limited power from the customer premise.  For these deployments, expected to be common, low DPU power consumption is critical. The efficient Ethernity’s solution enables ultra-low DPUs.

To support carrier grade requirements with the high-speed data plane, Ethernity offers a scalable solution with the new version of G.fast Digital Front-End (DFE). The scalable ENET platform supports DPUs with a range of NG G.Fast port configurations, including 8,12, 24 and 48 ports as well as a chassis configuration with 256 ports.

Integrated, channelized 10GbE interfaces connect directly to the G.Fast modems and multiplex the access data to 10GbE uplinks.  The Carrier Ethernet features of the ENET4840z/99 include L2 and L3 switching, EFM bonding and flexible uplink tunnelling.

The flow processor’s flexible H-QoS optimizes the use of variable speed cDTA links with fine-grained flow shaping and scheduling. The solution supports SDN through the Open Flow 1.3 API, extending SDN’s benefits to the access point for carriers that are looking to SDN to reduce network Opex and improve service agility.

Broadband solutions experts from Ethernity Networks explain the benefits and features of the ENET portfolio in detail at at BBWF 2017 in Berlin, at the booth C110B, between 24 and 26 October 2017.
