In this paper, a novel all-fiber band pass filter based on a concatenated structure of multimode fiber, single-mode core mode blocker and a single-mode long period fiber grating was reported. It can simultaneously serves as a band pass filter and multimode-single-mode converter for interconnection between multimode fiber and single mode fiber network. The theoretical analysis, designing, fabrication and experiments result were presented.
