MaxLinear MxL85110 Gigabit Modem Drives GiaX HelEOS™ Solution in Field Trials for 5G Mobile Backhaul over the Cable Network

  • Product deployments underway at the largest Tier-1 European Cable Operator


CARLSBAD, Calif.–(BUSINESS WIRE)–MaxLinear, Inc. (NYSE: MXL), a leading provider of radio frequency (RF), analog and mixed-signal integrated circuits for the connected home, wired and wireless infrastructure, and industrial and multimarket applications, today announced that GiaX GmbH is in production with its HelEOS network system that delivers 10Gbps symmetrical throughput over coaxial cable infrastructure and is powered by the MxL85110 gigabit modem system on chip (SoC).

The introduction of 5G has resulted in more challenging requirements in terms of throughput, latency, reliability, and density of connections. It has also exacerbated capacity constraints already experienced in mobile networks due to increased data traffic. Fiber is the default transport network used for mobile backhaul but its deployment can be costly and time consuming. The cost of equipment and labor can quickly add up, particularly with underground networks. Further, the time, cost, and uncertainty around securing necessary approvals can be equally burdensome.

Leveraging the high throughput and low latency provided by the MxL85110, the HelEOS solution provides a comprehensive Virtual Fiber™ solution that meets the evolving demands of mobile backhaul over the cable network without having to install fiber. By using the HelEOS solution, cable operators can take advantage of their existing coaxial infrastructure to backhaul traffic generated by 4G/5G mobile base stations. This solution enables a much faster network rollout and saves tens or potentially hundreds of millions of dollars in capital expenditures.

A tier-1 European cable operator is currently deploying the HelEOS solution over their existing coaxial network to provide a 10G Ethernet overlay network as backhaul technology for Remote PHY devices.

“We are excited that the HelEOS system is in production at a Tier-1 European operator and is being trialed for mobile backhaul applications. GiaX has addressed a capacity constraint within existing HFC networks enabling 5G backhaul deployment,” said Brendan Walsh, Vice President of MaxLinear’s Wireless Infrastructure Group. “By leveraging our technology, HelEOS supports data rates up to 10Gbps and has plenty of headroom to meet demands for increasing capacity. Our MxL85110 ensures throughput of up to 20Gbps is realizable using existing technology.”

“The HelEOS system has been designed to support mobile backhaul. With support of synchronous Ethernet, 1588v2, and a close to single-digit microsecond delay per hop, mobile 4G/5G backhaul over coaxial cable is now possible,” said Jörg Hellwig, CEO and Company Founder of GiaX. “Metro Ethernet Forum (MEF) operations and maintenance (OAM) type functionality of the HelEOS system will also be of use for the mobile operator.”

MaxLinear MxL85110 Provides 20Gbps Throughput

HelEOS uses MaxLinear’s MxL85110 chipset, which provides up to 20Gbps (10Gbps downstream and 10Gbps upstream) Ethernet capacity. The MxL85110 offers ultra-low latency of five microseconds per node and adaptive code modulation ranging from BPSK to 1024 QAM. The device can be programmed for flexible bandwidth from 25MHz to 2GHz, with independent asymmetric transmit and receive configuration. It also delivers the highest spectral and payload efficiency for efficient utilization of cable bandwidth with no MAC-layer overhead. Additional features used in the HelEOS solution include carrier-grade synchronous Ethernet and IEEE 1588v2 synchronization and an integrated management channel.

GiaX’s HelEOS Solution

The HelEOS 10G Ethernet overlay system is a modem and switch technology that combines point-to-point Ethernet connections over existing coaxial cables into an Ethernet overlay system on the HFC network. This Ethernet overlay system offers fiber-like speeds as well as MEF management functions. HelEOS can currently transport up to 10Gbps in both upstream and downstream directions. For the Ethernet data transmission, unused frequency spectrum above frequencies used for DOCSIS 3.x and DVBC or MPEG is utilized. Depending on the cable type and frequencies used, transmission can be accomplished over several hundred meters.
