Overview Specifications Related Products Order Now!
 SIMTRUM's DFB narrow-linewidth lasers cover the 1545–1560 nm wavelength range and deliver power up to 80 mW. They offer advantages such as low relative intensity noise (RIN), high output power, low operating current sensitivity, and high stability, and are primarily used in fiber optic communications, fiber optic sensing, and frequency measurement.

Features

  • Narrow Linewidth (200/350/800 kHz)
  • High Output Power
  • Low RIN

Butterfly Laser

Application

  • Fiber Communications
  • Fiber Sensing
  • LiDAR
  • Microwave Photonics
