Assembled broadband optical isolator capable of effectively reducing optical loss

Abstract

The invention discloses an assembled broadband optical isolator capable of effectively reducing optical loss, which comprises an isolator upper cover plate, a rubber air bag, a connecting plate and an extrusion block; the isolator upper cover plate and the isolator lower cover plate are both provided with connecting pieces through bolts, and are both connected with rubber rings through screws; a reset spring is welded and fixed to the connecting plate, the top end of the reset spring is welded and fixed to the isolator upper cover plate, and a rotating shaft is slidably connected into the limiting sliding groove. The assembled broadband optical isolator capable of effectively reducing the optical loss is provided with the connecting plate and the extrusion block, an optical filter can be pushed to the position above the connecting plate through the rotating shaft and a limiting sliding groove, at the moment, the optical filter can be conveniently and stably installed, and similarly, the optical filter can be disassembled and replaced by pushing the connecting plate upwards, so that the use diversity and stability of the isolator are improved.

Description

technical field [0001] The invention relates to the technical field of optical isolators, in particular to an assembled broadband optical isolator that can effectively reduce optical loss. Background technique [0002] Broadband optical isolator is a dual-port optical device with non-reciprocal characteristics. It attenuates the optical signal transmitted in the forward direction very little and attenuates the optical signal transmitted in the opposite direction greatly, forming a one-way path of light. , an optical isolator is connected between the laser and the transmission fiber, which can effectively suppress the reflected light generated from the far end face of the fiber, the interface of the fiber connector, etc. caused noise. [0003] However, most broadband optical isolators now have the following problems: [0004] 1. Conventional broadband optical isolators cannot be assembled and disassembled conveniently and stably during use, and thus cannot perform convenien...
