FlexDSL develops industrial communication solutions that enable high-reliability data transmission over existing copper infrastructure. These systems are applied where fibre deployment is impractical, and where long-distance communication, legacy integration, and operational continuity must be maintained across critical industrial environments.


FlexDSL Orion series extending Ethernet over copper across long distances

Extending Networks Where Distance And Infrastructure Constrain Connectivity

FlexDSL enables deterministic communication over copper where standard Ethernet limits and fibre deployment constraints would otherwise prevent connectivity.

Industrial networks often extend across distances and environments where fibre is not feasible. Standard Ethernet over copper is limited to short ranges, while trenching fibre introduces cost, delay, and operational disruption.

FlexDSL overcomes this by extending Ethernet over copper using SHDSL.bis technology, supporting:

  • Data rates up to ~15–18 Mbps per copper pair
  • Distances exceeding 6 km on a single pair, and significantly further using pair bonding

This enables stable communication for SCADA, telemetry, and control systems across existing infrastructure.

The result is not just extended reach. It is predictable, long-distance communication without replacing physical infrastructure.

Where This Applies

Utilities (Water, Gas, Electricity)
SCADA and telecontrol networks across substations and distributed assets where copper infrastructure already exists.

Rail & Transportation
Trackside communication, signalling systems, and long-distance communication along rail corridors.

Oil & Gas
Pipelines, remote monitoring systems, and production environments where communication loss directly impacts throughput and safety.

Industrial & Process Environments
Legacy-connected systems requiring integration into modern Ethernet-based architectures.

Hybrid Fibre-Copper Architectures

Fibre and copper networks operate together to maintain communication continuity across mixed infrastructure.

FlexDSL enables:

  • Fibre where available
  • Copper extension where required
  • Seamless transition between mediums

This supports resilient architectures in environments where full fibre deployment is not possible.

Industrial Resilience And Environmental Design

Communication infrastructure must operate reliably under harsh environmental conditions.

FlexDSL devices are designed for:

  • Extended temperature ranges
  • Vibration and mechanical stress
  • Moisture and outdoor deployment (including IP-rated devices)

This ensures stable communication in field environments where standard equipment would fail.

How FlexDSL Fits Into Industrial Systems

FlexDSL operates at the physical communication layer, extending connectivity to locations where network infrastructure would otherwise stop.

It enables:

  • Long-distance communication to remote assets
  • Integration of legacy systems into modern networks
  • Continuity across constrained infrastructure environments

FlexDSL does not replace switching, routing, or edge processing. It ensures that communication can reach the systems that depend on it.

Integration With Edge Systems (Welotec)

Extending communication is only valuable if the data can be processed and used at the point of operation.

FlexDSL delivers reliable data from remote assets over long-distance copper infrastructure.

Welotec platforms then:

  • Process that data locally (MQTT, OPC-UA)
  • Enable real-time analytics and decision-making
  • Support virtualised control environments (vPAC, IEC 61850)

Together, this enables:

  • End-to-end visibility from remote assets
  • Reduced latency in control loops
  • Stable hybrid fibre-copper architectures in substations and distributed systems

Communication is extended. Data is processed. Systems respond in real time.

Operational Impact

FlexDSL enables organisations to:

  • Reduce infrastructure costs by reusing existing copper instead of deploying fibre
  • Maintain communication across remote and distributed environments
  • Improve system visibility and fault detection in real time
  • Reduce downtime caused by communication loss
  • Accelerate deployment timelines in constrained environments
