Double-fiber SFP light receiving and emitting module with protection device

Abstract

The invention discloses a double-fiber SFP light receiving and emitting module with a protection device. The module comprises an SFP optical module body, wherein four groups of projections are symmetrically welded to the SFP optical module body; a rotating rod is welded between the two corresponding projections; a sleeve is arranged on the rotating rod in a rolling mode; a vertical plate is weldedon the outer side of the sleeve; a through hole is arranged in one side of the vertical plate; a hook surface of a hook-and-loop fastener is adhered to the rough surface of the hook-and-loop fastener, so that the two groups of dustproof cloth can cover the upper surface of the SFP optical module body, dust can be prevented from falling on the upper surface of the SFP optical module body, and thedust can be prevented from entering a wire joint of the SFP optical module body, and thus a connection between a wire cable and the SFP optical module body is more stable; and the two groups of concave blocks are connected together in a plug-in mode, when a collision occurs, a collision object can be in contact with a concave plate firstly, so that the collision object is prevented from being directly in contact with the SFP optical module body, and a possibility that the SFP optical module body is damaged is reduced.

Description

technical field [0001] The invention relates to the technical field of SFP optical modules, in particular to a dual-fiber SFP transceiver optical module with a protective device. Background technique [0002] SFP optical module is a hot-swappable small package module in SFP package. At present, the highest rate can reach 10.3G. The interface is LC. SFP optical module is mainly composed of lasers. SFP classification can be divided into rate classification, wavelength classification, and mode classification. The module consists of: laser (including transmitter TOSA and receiver ROSA), circuit board, IC and external accessories, and external accessories are composed of shell, base, PCBA, pull ring, buckle, unlocking piece, and rubber plug. Easy identification Generally, the parameter type of the module can be identified by the color of the pull ring. [0003] Common SFP optical modules are generally plugged with wires and cables at the connectors during use, but common SFP opt...

AI Technical Summary

Problems solved by technology

[0003] Common SFP optical modules are generally plugged with wires and cables at the connectors during use, but common SFP optical modules do not have the function of dust protection. If dust enters the connectors of the SFP optical module, it is easy to affect the wires and cables and the SFP optical module. The stability of the connection, and, if the SFP optical module is bumped, it is prone to damage
