DTS Pulsed Laser (Distributed Fiber Temperature Sensor)
The DTS pulsed laser integrates a nanosecond seed and fiber power amplifier for distributed temperature sensing, laser ranging and fiber sensing. Optimized pulse-drive circuitry and a low-noise EDFA provide stable, high-peak-power pulses with little distortion. External triggering is used; serial configuration sets pulse width, peak power and other parameters. High integration, compact size and easy debugging are provided. Strict environmental testing ensures long-term reliability and stability.
