Packaging shell of multipath optical transmitting and receiving module

The utility model relates to the field of optical communication and discloses a packaging shell of a multipath optical transmitting and receiving module, which comprises two tail tubes serving as optical interfaces and a box body. A frame body, cover plates and a circuit board serving as an electrical interface are sealed and assembled to form the box body; the box body is internally separated into two accommodating spaces via a baffle for accommodating an optical transmitting module and an optical receiving module respectively; and the two cover plates are respectively used for sealing the two accommodating spaces. The baffle is used for physically separating the shell into two accommodating spaces, the two accommodating spaces are respectively provided with cover plates, the TOSA and the ROSA can be arranged conveniently, a ceramic module with a circuit is adopted to serve as one part of the shell, the mounting efficiency and reliability are improved, maintainability is enhanced, mutual crosstalk is reduced
