THE HAGUE, NETHERLANDS — dataMate, a business unit of Methode Electronics, a global developer and manufacturer of custom engineered and application-specific products and solutions, along with MaxLinear, a provider of mixed-signal integrated circuits for the broadband market, and LEA Networks, a provider of home networking, announced a new G.hn-based fiber-to-the-distribution-point (FTTdp) platform designed to dramatically lower the cost of delivering gigabit broadband services for service providers.

The Methode micro-DPU is the first single-port “distribution point unit” in the market that allows service providers to natively leverage existing twisted pair or coaxial cable infrastructure in their fiber deployments, which significantly reduces installation costs and guarantees a gigabit broadband experience in both upstream and downstream directions.

G.hn is an ITU networking standard that delivers data rates up to 2 Gbps and can operate over a variety of copper media. Multiple service providers today rely on G.hn technology to deliver broadband services to millions of users in North America, Europe and Asia.

The Methode micro-DPU has been designed in close collaboration with TELUS’ engineering team to address the technical, operational and competitive business challenges of gigabit broadband service providers like TELUS.

Single-Port Micro-DPU Enables Pay-as-You-Go Model
“Most existing FTTdp solutions in the market require service providers to make large upfront investments before a single customer signs up for service. Installing a 16-port DPU when only one subscriber has signed for service does not make much financial sense,” said Chano Gómez, Sr. director, G.hn marketing at MaxLinear. “The single-port micro-DPU solves this problem by enabling pioneering carriers such as TELUS to adopt an innovative pay-as-you-grow model, adding new G.hn ports gradually as new customers sign up for service in an MDU or condominium. The unique auto-sync and cross-talk management provided by our VectorBoost technology enables multiple independent DPUs to be installed near each other, with a deployment model that was not possible before.”

Modular Architectures Reduce Deployment Costs
Methode General Manager Al Chiappetta added, “For years Methode has been a leading supplier of pluggable modules for the networking industry, and we are glad to see that the broadband access industry is also increasingly adopting modular architectures to reduce their deployment costs and increase flexibility. By collaborating closely with TELUS’ experienced engineering team, we are confident that our micro-DPU platform can meet the requirements of other service providers who want to reduce the cost of their FTTH deployment.”

“Reverse Power Feed is one of the three DPU powering options defined by BBF TR-301, and thanks to our extensive expertise on powering, splittering and filtering at very high frequencies, we have come with an industry-leading open architecture solution around RPF,” said Thierry Fernandez, CEO of LEA Networks. “Thanks to LEA’s optimal implementation of reverse power feed injector, TELUS and service providers around the world will be able to affordably reverse power DPUs with minimal insertion loss at maximum loop length, helping them reduce installation time and costs.”

“As TELUS continues to deploy fiber as close to customers as possible, we recognize there are key deployment scenarios where we need to take advantage of the existing copper drop or riser,” said David Moore, director of broadband access standards at TELUS. “The modular nature of the micro-DPU ensures it will continue to support our evolving network in both WAN and LAN environments.”

Technical Details: Methode micro-DPU

The Methode micro-DPU is the first FTTdp DPU in the industry that offers the following set of capabilities:

  • Data rates up to 2 Gbps, leveraging the latest 200 MHz G.hn band-plans standardized in ITU-T G.9960 Amendments 1 and 2.

  • Complete modularity, with replaceable SFP modules both for uplink (PON ONT) and downlink (G.hn over twisted-pair, G.hn over coax, 1G and 2.5G Ethernet over Cat-5e cable).

  • Maximum power usage of 10 watts, with flexible powering options, including both local 12V DC power and Reverse Power Feeding (RPF ETSI TS 101 548) over twisted pair or coax.

  • Available in both indoor and outdoor configurations.

  • ITU-T K.21 over-voltage protection.

  • Automatic detection of neighbor DPUs, with automatic synchronization of TDD time slots to eliminate near-end cross-talk (NEXT).

  • Compatible with MaxLinear cloud-based VectorBoost platform to eliminate far-end cross-talk (FEXT).

  • Flexible bandwidth provisioning, supporting both fixed TDD ratios or dynamic time allocation (DTA) on both coax and twisted-pair.

  • Directly supported in mainline OpenWRT, with the latest Linux 4.14 LTS kernel and Open vSwitch 2.92. The micro-DPU will be an SDN-ready software platform with no dependency on proprietary vendor SDKs.


Service providers planning to deploy the Methode micro-DPU have several options for G.hn connectivity in a pluggable SFP form factor ranging from an F-type connector for coax, RJ11 for phone line and RJ45 for Cat-5e cable. All Methode’s G.hn SFP modules integrate MaxLinear’s G.hn Wave-2 chipset and are fully interoperable with G.hn products from other vendors. The SFP modules are designed to be used both on the micro-DPU side or in third-party residential gateways, simplifying inventory management by service providers.

Technical Details: LEA PSETT02US

The PSETT02US from LEA Networks is a reverse power injector based on the ETSI TS 101 548 standard. Product features include:

  • Simple, easy reverse power feed (RPF) self-installation power supply equipment (PSE).

  • Combines modem data with power to reverse power DPU.

  • Available in power class SR2 (15 watts) and SR3 (21 watts).

  • Native support for twisted-pair interface, with optional plug-in to enable coax cable support and Gigabit Ethernet.

  • Support for SISO and MIMO over twisted-pair.

  • Compliant with metallic detection-based start-up (MDSU) protocol.

  • Wall mount and desk mount option for C-5 universal AC cord adapts to any international plug type.
