Powering Mission-Critical Infrastructure
KER Network is a Singapore systems integrator for Distributed Temperature Sensing (DTS), fibre optic infrastructure, security and ATEX hazardous-area systems. We design, supply, install, commission and support complete systems for data centres, power networks and industrial plants.
Solutions
DTS is our specialism. Our cabling, security and hazardous-area teams make sure the whole system is installed, tested and documented to one standard.
A single optical fibre becomes a continuous temperature sensor, with a reading every half metre along kilometres of cable. DTS finds the exact location of a hotspot and alarms before it becomes a fault, fire or outage.
Single-mode and multimode fibre, fusion splicing, ODFs and Cat6/6A copper. Every link is OTDR tested, certified and documented.
Fibre optic solutions →IP CCTV with video analytics, access control and perimeter intrusion detection, brought together on one monitoring platform.
Security systems →Explosion-proof enclosures, networking and communication equipment for Zone 1 and Zone 2 areas, supplied with ATEX/IECEx documentation.
ATEX solutions →Applications
Point sensors only see where they are mounted. A sensing fibre sees the whole route, so faults are found wherever they start.
How we deliver
One team carries the system through every stage, so nothing is lost between the designer, the installer and the commissioning engineer.
Site survey, fibre routing, zoning and alarm philosophy.
Controllers, sensing cable and accessories matched to the application.
Cable laying, fixing and low-loss fusion splicing.
OTDR testing, calibration, zone mapping and alarm verification.
Alarms and data to BMS, EPMS or SCADA via relays or Modbus.
Maintenance, health checks and on-call service.
DTS at a glance
Exact figures depend on the controller, fibre type and route. We size each system to the application during design.
| Measuring principle | Raman backscatter in optical fibre |
|---|---|
| Range per channel | A few km up to tens of km |
| Spatial resolution | 0.5 m |
| Temperature resolution | 0.1 °C class |
| Update time | Seconds to minutes per channel |
| Alarm types | Max temp, rate of rise, deviation from zone average |
| Outputs | Relays, Modbus, software alarms |

FAQ
DTS uses a laser and a standard optical fibre to measure temperature continuously along the full length of the cable. Every half metre of fibre becomes a measuring point, so one fibre can replace thousands of point sensors and show exactly where a hotspot is.
A sensing fibre is run along busduct joints, tap-off units and switchboard sections. Loose or degraded joints heat up before they fail, and DTS alarms on the temperature rise and its location, giving the facility team time to act before an outage or arc flash.
Depending on the DTS platform and configuration, a single channel typically covers from a few kilometres up to tens of kilometres, with spatial resolution down to 0.5 metres. Multi-channel units can monitor several routes from one controller.
Yes. DTS controllers provide zone alarms and temperature data through dry contacts and industrial protocols such as Modbus, so alarms can be passed to a building management, power monitoring or SCADA system.
We work directly with facility owners and operators, and as a specialist subcontractor to main contractors, M&E contractors and consultants on design, supply, installation, testing and commissioning.
