Long-Distance Ethernet And Legacy Integration Over Copper Infrastructure
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.
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.

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.

Key Product Capabilities
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:
Communication is extended. Data is processed. Systems respond in real time.
