Abstract

The invention provides a BIDI QSFP28 optical module which is characterized in that the BIDI QSFP28 optical module comprises a base assembly part, a fiber coiling frame, a metal sleeve, a PCB device assembly part and an upper cover, wherein the PCB device assembly part is placed on the fiber coiling frame, the metal sleeve clamps the fiber coiling frame, the fiber coiling frame is fixed to the base assembly part, the PCB device assembly part, the fiber coiling frame on which fiber coiling is completed and the metal sleeve are placed into the base assembly part together, and the fiber coiling frame, the metal sleeve and the PCB device assembly part are assembled and packaged in the base assembly part and the upper cover. The positioning problem of a plurality of devices in the BIDI QSFP28 module and the fiber coiling problem in a narrow space are solved, the TOSA device, the ROSA device and the WDM device are packaged in the BIDI QSFP28 module through the ingenious fiber coiling and positioning mode, and the structural layout of the components in the compact module space is well achieved. The invention further discloses a small metal connector which is used for connecting the optical fiber and the device.

Description

technical field [0001] The invention belongs to the technical field of optical communication, and more particularly relates to a BIDI (Bidirectional) QSFP28 optical module. Background technique [0002] With the rapid development of optical networks, fiber resources will become more and more tense, and the demand for solutions to save fiber resources will gradually increase. At the same time, the working temperature of the module is also a trend, so that it does not need to be deployed in the computer room, greatly reduces the requirements for site selection, and saves subsequent maintenance costs. Based on this, it is extremely demanded in the market to create an optical module product that not only meets the industrial temperature, but also saves fiber resources. [0003] The BIDI optical module is a single-fiber bidirectional optical module, that is, BiDi (Bidirectional). Specifically, it uses WDM (Wavelength Division Multiplexing) technology to transmit and receive opti...
