DK Photonics’ 780nm&850nm Fiber Mirror Reflector are designed to reflect light input through mirror backward through the fiber. Our Fiber Mirror Reflector are available with single mode (SM), polarization-maintaining (PM), or multimode (MM) fiber. They can be used to create a fiber interferometer or to build a low-power fiber laser. These Fiber Mirror Reflector are ideal for determining back reflection specifications for transmitters, amplifiers, and other devices.
