Polarization-maintaining fiber splitter PMFS
Classification:
As a passive optical element, the function of the polarization maintaining fiber splitter is to realize the splitting of the light wave power under the premise of maintaining the original polarization state of the light wave. The polarization maintaining fiber beam splitter is manufactured by micro optics and mature glass tube technology. It has the advantages of low WDL, low PDL, wide working temperature range and working wavelength range. The fiber pigtail can be customized as polarization maintaining (PM) fiber or single mode polarization maintaining (SM/PM) fiber.
