Combination circulator assembly and circulator

The invention relates to the field of optical communication, in particular to a wave combining circulator assembly and a circulator, and the wave combining circulator assembly comprises a bottom plate, and the circulator and a wave combiner which are arranged on the bottom plate; optical signals are transmitted through cooperation of a first polarization splitting prism, a second polarization splitting prism, a third polarization splitting prism, a fourth polarization splitting prism and a Faraday rotating piece in the circulator, the anti-crosstalk capacity of the circulator can be effectively improved, and the wave combining function can be achieved through cooperation with a wave combiner. The combiner circulator assembly can ensure good anti-crosstalk capability without additionally arranging an isolator, has the characteristic of small device size, and can meet the requirement of miniaturization of the device. 本发明涉及光通信领域，尤其涉及一种合波环形器组件及环形器，所述合波环形器组件包括：底板，设置在底板上的环形器和合波器；其中通过环形器中第一偏振分光棱镜、第二偏振分光棱镜、第三偏振分光棱镜、第
