What is the lifespan of a mechanical optical switch?

The service life of a mechanical optical switch usually depends on several factors, including the type of switch, the operating environment, the load requirements, the operating frequency, etc. Generally speaking, the service life of a mechanical optical switch can reach 100 million operations or more, especially in low-load and non-extreme environments.

If it is in a high-frequency switching application, or is exposed to environmental conditions such as high temperature, humidity, vibration, etc., the service life may be shortened. In addition, wear of mechanical parts over time will also affect its performance.

To extend the service life of a mechanical optical switch, the following measures can be taken:

Avoid frequent switching operations, especially under high-load conditions. Keep the device dry and clean to avoid dust, moisture, etc. affecting its mechanical parts. When used in extreme environments, consider using a special sealing or protective design.

Transmission distance of single-mode fiber and multi-mode fiber

Single-mode fiber (SMF): Due to its small core diameter and lower attenuation, single-mode fiber is suitable for longer transmission distances. Single-mode optical fiber can achieve signal transmission of tens of kilometers or even hundreds of kilometers, and is especially suitable for long-distance communications and cross-continental and cross-sea optical fiber cables. Multimode fiber (MMF): Multimode fiber is suitable for shorter transmission distances, generally in the range of several kilometers. Due to dispersion problems and attenuation, the transmission distance of multimode fiber is relatively limited and is more suitable for local area networks, short-distance communications and some low-bandwidth applications.
