[0018] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0019] Please see attached Figure 1 -2, a fiber optic module provided by the present invention comprises a fiber optic flange 1, an optical fiber 2 and an optical module 3 connected in sequence; the fiber optic flange 1 and the optical module 3 are both provided with a fiber optic interface connected to the optical fiber 2, and oil-resistant glue 4 is encapsulated between the optical fiber 2 and the fiber optic flange 1 and the fiber optic interface of the optical module 3. The fiber optic flange 1 comprises a connecting portion 11 and a fiber optic adapter 12 connected to the connecting portion 11, the fiber optic interface of the fiber optic flange 1 is provided on one side of the connecting portion 11, and a notch for engaging the fiber optic adapter 12 is provided on the other side of the connecting portion 11.

[0020] Based on the above technical features, the connection gap between the optical fiber 2 and the optical fiber interface is sealed by using oil-resistant glue 4, thereby isolating the contact between the optical signal and liquids such as coolant, and avoiding the influence of the medium on the propagation of the optical signal; by providing the optical fiber flange 1, when the equipment box needs to be moved, the externally connected optical fiber 2 can be disassembled first, which is convenient for movement and maintenance. The optical fiber adapter 12 and the optical fiber are connected through the connecting part 11, the equipment is connected through the optical fiber adapter 12, and the optical signal is transmitted through the connection between the optical fiber 2 and the optical module 3, which is convenient for later disassembly and maintenance.

[0021] An annular fitting groove is arranged on the outer periphery of the notch, and a sealing ring 13 is fitted in the fitting groove. By providing the sealing ring 13, the sealing performance of the connection between the optical fiber adapter 12 and the device is improved to prevent leakage of the cooling liquid.

[0022] The glue 4 is epoxy resin glue or acrylic resin glue. Different types of oil-resistant glue 4 can be used to seal the gap between the optical fiber and the optical fiber interface to achieve the sealing of the connection between the light and the optical fiber interface and isolate the contact between the liquid and the optical signal.

[0023] The type of the optical module 3 is SFP or GBIC or XENPAK or XFP, and the type of the optical fiber adapter 12 is LC or SC or ST or FC; different optical modules 3 and optical fiber adapters can be selected for adaptation and application according to different usage scenarios.

[0024] The number of optical fiber interfaces of the optical fiber flange 1 and the optical module 3 are both two, which increases the number of optical fibers 2 of a single optical fiber module and reduces the number of modules when being installed.

[0025] The cross section of the connecting portion 11 is rectangular, which is convenient for processing and subsequent installation.

[0026] The depth of the notch is 6-10 mm, preferably, the depth of the notch is 8 mm, so as to realize the connection between the optical fiber adapter and the connecting part.

[0027] The cross section of the fitting groove is rectangular, so as to achieve a better sealing effect of the sealing ring 13 .

[0028] The optical fiber adapter 12 is fixed in the slot by fixing screws to increase the firmness of the optical fiber flange.
