3 port PM Circulator

It is a high-end optical device that combines non-reciprocal optical routing and polarisation preservation capabilities, capable of transmitting optical signals in a directional manner (Port 1→2→3) while strictly preserving the polarisation of the incoming light (e.g., in the direction of linear polarisation)
