Sissejuhatus To Optical Isolaatorid

A dual-port optical device with non-reciprocal properties. It on little attenuation to the optical signal transmitte in the forward direction and a large attenuation to the optical signal transmitte the other direction, forming a one-way path of light. Ühendamine an optiline isolaator vahel the laser ja ülekanne kiud saab tõhusalt summutada the peegeldunud valgus genereeritud from the far end face of the fiber and the fiber connector in the line from return to the laser, seeläbi ententing the stability of the laser working state and reducing the system caused by reflected light. noise. this is even more important for high-speed optical fiber communication coherent optiline fiiber side süsteemid.
Optical isolaatorid on nõutav to on madal insertioon loss (for example, 0.5dB), low isolation reverse loss, or large forward loss (for example, 30dB).
There are many types of optical isolators, peamiselt plokk optical isolaatorid, all-fiber optical isolators, integrated optical waveguide optical isolators, and polarisatsioonist sõltumatu optilised isolaatorid.
