▎Fiber Optical Coupler
Fiber optical coupler, an optical device that realizes the distribution or combination of optical signal power among different optical fibers. It is formed by utilizing the mutual exchange of guided wave energy in different optical fiber surfaces adjacent to the optical fiber core area. According to the type of fiber used, it can be divided into multimode fiber coupler, single mode fiber coupler and polarization maintaining fiber coupler.
Optizone's couplers are mainly polarization maintaining filter-type couplers, which have the characteristics of high extinction ratio, low excess loss, and more compact size.
