Abstract

The invention discloses an optical module and a circular and square tube body, and belongs to the field of optical fiber communications. The optical module comprises a detector and the circular and square tube body, wherein a TO cap is arranged on the detector; the circular and square tube body comprises a circular tube body and a square tube body which are communicated with each other, a groove is formed in one side face of the square tube body, an opening for being matched with the TO cap is formed in the bottom surface of the groove, and the top area of the groove is greater than the area of the opening surface of the opening. The problem that the coupling value for TO coupling is relatively small is solved. The benefit of improving the qualified rate of the optical module is realized. The optical module is used for TO coupling of the detector.

Description

technical field [0001] The invention relates to the field of optical fiber communication, in particular to an optical module and a round and square tube body. Background technique [0002] Compact small form-factor pluggable (English: Compact small Form-factor Pluggable; abbreviation: CSFP) optical transmitter and receiver assembly (English: Bi-Directional Optical Sub-Assembly; abbreviation: BOSA) is a miniaturized packaged single-fiber bidirectional optical The component is applied to an optical module (English: optical module), and has a compact structure. When realizing its function, laser diode module (English: laser diodemodule) coaxial type packaging (English: Transistor-Outline CAN; abbreviation: TO-CAN), usually referred to as TO coupling, needs to be carried out first. [0003] TO coupling includes laser welding and detector coupling. Laser welding refers to welding the laser with the round and square tube through the coaxial package, and assembling the round and ...
