Optical fiber coupler is an optical device that distributes or combines optical signal power among different optical fibers. It can be realized by three ways: melt-pull sintering, micro-optics and optical waveguide. We can provide the above three specifications according to customer's needs. We can also provide more selection in wavelength, power and spectral ratio.
