Home / Optical module transmission wavelength
The wavelengths of optical modules usually include 850nm, 1310nm, 1550nm, etc. Among them, the 1550nm wavelength is widely used for long-distance transmission because it has the lowest fiber loss and smallest dispersion. Optical modules are crucial for today's communication systems as they convert electrical signals into light signals for rapid data transfer. Due to process and production variations, different types of lasers or the same type of laser may have differences in central wavelength.
