Atenuator de fibra optica Cunoștințe din industrie

As a specially designed optical passive device, the optical fiber attenuator plays an irreplaceable role in regulating optical power and optimizing system performance. Whether it is a long-distance trunk network or a data center interconnection, the optical fiber attenuator silently guards the stable transmission of optical signals and prevents communication failures caused by excessive or low power.

Principiul de funcționare al atenuatorului de fibră optică
Absorption attenuation technology: Attenuation is achieved by using materials that selectively absorb light waves of a specific wavelength. The required attenuation can be obtained by precisely controlling the thickness or area of the absorbing material. The advantage of this technology is that the attenuation stability is high and the wavelength correlation is small. The thickness control accuracy of the metal film prepared by the ion sputtering process can reach ±2nm, which can achieve precise control of the attenuation value.

Reflection attenuation technology: A dielectric film with a certain reflectivity is introduced into the optical path, so that part of the optical signal is reflected instead of transmitted. The desired attenuation effect can be achieved by precisely controlling the reflectivity through the film system design. The advantage of this type of attenuator is that it is low in sensitivity to wavelength and is suitable for broadband optical network applications.

Gap attenuation technology: Using the Fresnel reflection principle, a precisely controlled tiny air gap is introduced between the two optical fiber end faces. There is a definite relationship between the gap size and the attenuation. By adjusting the gap distance with precision machinery, an attenuation range of 0-15dB can be achieved. This structure is simple and reliable, with low cost, and is often used in economical application scenarios.
