High Power Fiber Cables 

Normally fiber patch cables with connectors such as SMA can tolerate only around 1W of power. Just several hundred milliwatts of leaked power will heat the epoxy inside the ferrule. This causes the epoxy to liquify and cover the end face, which in-turn leads to attenuation, localized heating, and quick power degradation. In contrast, high power fibers are designed to operate with high power application. They feature air-gap-ferrule technology that excludes the absorption of the light energy by materials around the fiber end face. In addition, both ends are coated with Anti-Reflection coating for 400-700nm. The threshold damage of the coating is >1MW/cm2, the threshold damage value will vary with launch conditions and operating wavelength.

  • This is a high-power fiber optic cable with 400μm / 0.22NA fiber, SMA connectors, and a visible anti-reflection (AR) coating. It is 2m long and can handle power levels above 30W due to the air-gap SMA connector, which does not require heat sinking. The high-power fiber cable is 2m long and is AR coated for 400 –...
