1×N Optical Signal Distribution Low PDL FBT Coupler

The single-mode coupler fused two or more fibers under high temperature heating conditions and stretches them to both sides. By controlling the twist angle and stretch length of the fiber, different light splitting ratios can be obtained. It is mainly suitable for passive The optical signal distribution and monitoring in the optical network (PON) system is one of the most important passive components in the optical network; the single-mode taper coupler provided by GFR has 1x2, 2x2 and multiple splitting ratios to choose from, satisfying customers Diversified requirements; the tapered coupler has the advantages of wide working wavelength range, small size, high stability and reliability, and is currently widely used in optical network monitoring, optical fiber sensing, FTTX, CATV etc.
