As shown in fig. 1, 2, 3, and 4, an MPO connector includes:
the tail seat structure comprises a shell 1, wherein a front-back through cavity 17 is arranged in the shell 1 and used for containing a tail seat 4, a spring 13 and other parts, fixing grooves 2 are formed in two sides in the cavity 17, and a limiting boss 3 is arranged at the front part of the cavity 17;
