1550nm Pulsed Laser Source Fiber Laser for DTS

The 1550nm laser source is one pulsed fiber laser special designed for distributed fiber temperature measurement application. It offers excellent performance by optimizing backward traveling light, low-noise EDFA and wide working temperature. The laser source integrated a pulse signal generator inside. It can also be triggered via an external signal. Rigorous environmental testing ensures its long-term reliability and stability, making it ideal for OEM integration.

LumiMetriC developed Erbium fiber lasers in MOPA configuration offers customers a constant high peak power over a wide range of pulse repetition rate values for stable high performance. With low weight and small size, these lasers are easily deployed. At the same time, the solid construction is maintenance free and reliable, ensuring long-life operation at low operation cost.
