Types Of Optical Isolators

There are many types of optical isolators, including in-line optical isolators, free space optical isolators, etc. We provide optical isolators of various specifications to meet the needs of different application fields. The internal design of the 1310/1480/1550nm polarization-independent optical isolator is based on the process of separately processing the two orthogonal polarization states in the single-mode fiber to ensure the polarization-independent characteristics of the entire device. Unipolar devices have low insertion loss, and bipolar devices have extremely high optical isolation. They are suitable for different applications, mainly used in fiber amplifiers, fiber lasers, fiber optic CATV networks and satellite communications.
Optical isolators are generally distinguished by wavelength, most of which are 800-1300nm, and there are also some special wavelengths.
Connect the output end of the LD light source to the optical power meter through an optical fiber jumper, and read its output power from the optical power meter, that is, the input power of the optical isolator.
