Quad small form-factor pluggable (QSFP) optical module with tail fiber

Abstract

The invention relates to the technical field of optical communication transmission, in particular to a quad small form-factor pluggable (QSFP) optical module with a tail fiber. The QSFP optical modulecomprises an optical module shell, wherein the optical module shell comprises a base, an upper cover and a pull rod, the base and the upper cover are connected by a bolt, the pull rod is arranged onthe base, a circuit board is arranged in the optical module shell, a connection block, an MT core insertion male head and an MT core insertion female head are further arranged in the optical module shell, the connection block is fixedly arranged at a tail part of the base by a bolt, a round through hole is formed in the connection block, a tail sleeve is connected with the round through hole, thetail fiber sequentially passes through the tail sleeve and the round through hole and is connected with the MT core insertion female head, the MT core insertion female head is plugged to the MT core insertion male head, and the MT core insertion male head is connected with the circuit board. The QSFP optical module is simple in structure and extremely low in production cost and is convenient to process, optical path abutting is facilitated, the internal structure of the optical module is greatly simplified, a clamp is not needed to be helped to do optical coupling operation, and the reliability can be ensured very well.

Description

technical field [0001] The invention relates to the technical field of optical communication transmission, in particular to a QSFP optical module with pigtails. Background technique [0002] QSFP (Quad Small Form-factor Pluggable), that is, four-channel SFP interface (QSFP), QSFP was born to meet the market's demand for higher-density high-speed pluggable solutions. With the development of optical communication technology, optical modules with pigtails have been widely used because of their simple plug-in and convenient operation. At present, the common connection method between the optical module and the external pigtail is: inside the optical module - pigtail - optical fiber plug - flange - optical fiber plug - external optical fiber; here, the optical fiber plug, the flange The part is relatively long, so it takes up a lot of space on the printed circuit board (PCB, Printed Circuit Board) inside the optical module; at the same time, more plug-in connections also increase...
