T-Laser DTS

T-Laser is Bandweaver’s advanced fiber optic temperature monitoring system designed for precise, real-time condition assessment of critical infrastructure. Using Distributed Temperature Sensing (DTS) technology, T-Laser continuously measures temperature along the length of an optical fiber, providing accurate profiles over distances of up to 40km per channel.

It is ideal for applications such as underground and subsea power cables, pipelines, industrial process lines, and leak detection. With high spatial resolution, rapid data acquisition, and robust performance in harsh environments, T-Laser delivers actionable insights that help operators prevent failures, optimise performance, and extend asset life, all while integrating seamlessly with SCADA and control systems.

APPLICATIONS

Power Cable Monitoring

Underground and Subsea Cables – Continuous temperature profiling for high-voltage transmission and distribution cables.

Real-Time Thermal Rating (RTTR) – Adjust load capacity dynamically based on real conditions.

Fault Detection – Pinpoint hot spots, joint failures, or sheath damage.

Pipeline Monitoring

Leak Detection – Identify thermal anomalies caused by escaping fluids or gases.

Flow Assurance – Monitor temperature to prevent blockages from hydrate or wax formation.

Industrial Process Monitoring

Chemical and Refining Plants – Track process line temperatures to maintain safety and efficiency.

Furnaces and Kilns – Monitor thermal distribution for process optimisation and safety compliance.

Renewable Energy

Offshore Wind Farms – Monitor export and inter-array cables for overheating or damage.

Solar Farms – Oversee underground cable networks linking PV arrays to inverters/substations.

Structural Health Monitoring

Dams, Bridges, and Large Structures – Track temperature-related stresses or detect seepage.

HOW IT WORKS

The T-Laser Technology Principle is based on fiber optic Distributed Temperature Sensing.

Laser Pulse Transmission – The FireLaser unit sends precise laser pulses into a standard fiber optic sensing cable.

Backscatter Signal Return – As the light travels along the cable, it interacts with the glass fibers and a tiny portion of the light is scattered back.

Location Determination – FireLaser calculates the exact location of the temperature event, accurate to within ±1m.

Temperature Measurement – Changes in the backscattered light pattern (Raman scattering) are analysed to determine the temperature at every point along the cable.

Continuous Monitoring – The system monitors the entire cable in real time, detecting any abnormal rise in temperature.

Alarm Triggering – When a temperature threshold or smart alarm condition is met, FireLaser triggers alarms for the specific zone.

System Integration – Alarms are transmitted to fire panels, SCADA, or BMS for rapid operator action, often alongside CCTV activation.

Event Logging & Reporting – All events are logged for post-incident analysis, compliance, and maintenance planning.

SYSTEM INTEGRATION

T-Laser Interfaces and System Integration

Bandweaver has operated as a system integrator for more than 10 years and has a full range of services from system design through to installation and commissioning.
We have extensive experience in designing our systems to interface with standard industrial formats and specific customer requests.

Bandweaver has designed specific customer user interfaces to consolidate, manage, and visualise both DTS data (including third party DTS systems) and other integrated data feeds. Equally, Bandweaver is also comfortable exporting data into third party systems and networks. Examples of some of the interfaces Bandweaver has worked with include:

SCADA

Modbus / DNP3

WITSML

Electrical Relay Outputs

OPC / IEC61850 / Generic Object-Orientated Substation Events

SOLUTIONS

Bandweaver’s range of fiber optic monitoring systems are designed specifically to enhance the fire safety of critical infrastructure and personnel.

We provide solutions for fire detection utilising linear heat detection technology, monitoring environments over a long-range distance (linear assets), typically in special hazard environments.

LHD systems can detect a fire anywhere along the length of the linear heat-sensing cable, over a distance of several kilometres. Bandweaver utilises fiber optic distributed temperature sensing, one of the key technologies available within this field.

Combined with our smart software and services, this solution provides operators with the right information at the right time.

Whether the asset is in a remote location or a busy inner city, Bandweaver’s solutions enable swift decision-making and help to minimise damage and consequently avoid catastrophic failure and to reduce financial, environmental, and reputational risk.

FREQUENTLY ASKED QUESTIONS

Product Overview & Technical Capabilities

What is RTTR?
Real-Time Thermal Rating (RTTR) is a monitoring solution that calculates the safe, dynamic operating capacity of power cables and overhead lines based on real-time temperature measurements and environmental conditions.

How is RTTR different from static rating?
Static ratings use fixed, worst-case assumptions, while RTTR adapts to actual conditions (soil, weather, load), allowing operators to safely increase capacity.

Which Bandweaver products support RTTR?
RTTR is enabled using DTS (Distributed Temperature Sensing) and integrated with Bandweaver’s T-Laser and MaxView platforms.

Installation & Integration

What parameters does RTTR monitor?
Cable temperature profiles, soil/ambient temperature conditions and cable load.

How accurate is RTTR?
Temperature resolution from ±1°C (depending on proximity of fiber to power cable) with location accuracy to ±1m along the cable.

Does RTTR detect faults?
Yes – it identifies hotspots, deteriorating joints, sheath damage, and thermal anomalies.

What is the update frequency?
Typically every few seconds, configurable depending on cable length and system design.

Commercial & Support

What is the warranty period?
Standard two years, extendable to five years with service agreements.

What is the lifespan of the sensing cable?
25+ years under normal operating conditions.

What maintenance is required?
Minimal – mainly software updates, health checks, and fiber termination cleaning.

Is training available?
Yes – Bandweaver provides installer, operator, and utility engineer training.
