Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber transceivers, in particular to a stable optical fiber transceiver. Background Art

[0002] A fiber optic transceiver is an Ethernet transmission media conversion unit that interchanges short-distance twisted-pair electrical signals with long-distance optical signals. It is widely used in the field of fiber optic communications. During the startup process, the fiber optic transceiver will generate current, and the generation of current will cause dust in the air to be adsorbed into the interior of the fiber optic transceiver. Long-term dust accumulation will cause a series of adverse consequences for the fiber optic transceiver, such as heating. Therefore, the fiber optic transceiver needs to be protected from dust. The current dustproof component design is relatively simple. Generally, a filter is set at the vent of the shell. However, dust is easily accumulated on the filter after long-term use, which in turn affects the normal heat dissipation and ventilation of the fiber optic transceiver. The current equipment is not easy to remove dust, so it needs to be improved. Utility Model Content
