2000nm Polarization Maintaining Isolator

2023-02-28 15:59:51

Product description:

Optical isolator, also known as Faraday isolator, is a kind of magneto-optic device, which can perfectly make light wave forward propagation, and absorb or change the propagation direction of back propagation light wave at the same time. The optical fiber isolator can protect the light source, prevent it from being affected by directional reflection and signal, and avoid causing intensity noise and optical damage.

Product features:

1. High isolator, low insertion loss

2. High reliability and environmental stability

Product application:

1. Optical fiber amplifier

2. Fiber laser

3. Optical fiber sensor
