Why Optical Communication
Fiber-based platforms have become standard due to stability, compactness, and immunity to alignment issues compared to bulk lasers. They support long-term operation without frequent adjustments.
Introduction to Fiber Lasers in Optical Communication
Optical communication systems transmit information using light through fiber. A highly stable laser source ensures reliable modulation, long-distance transmission, and high spectral purity. Fiber lasers provide narrow spectral linewidth, excellent wavelength stability, low RIN, thermal control, and integrated fiber-coupled outputs — making them ideal carriers for modern networks.
- Narrow spectral linewidth
- Long-term wavelength stability
- Low relative intensity noise
- Fiber-coupled output
- Compatibility with modulation and amplification stages
Why the Right Laser Source Matters in Optical Communication
Minor fluctuations in wavelength, linewidth, or noise can degrade transmission quality in DWDM and coherent systems. Choosing a stable laser improves system margin and receiver sensitivity.
