Technical Field

[0001] The utility model relates to the technical field of OLT equipment, in particular to an OLT equipment with a VLAN port. Background Art

[0002] An optical line terminal (OLT), also known as an optical line terminal (OLT), is a crucial device in fiber-optic access networks. It plays a crucial role in fiber-optic communication systems, connecting fiber trunk lines with user-end devices, converting optical and electrical signals, and providing a variety of network functions.

[0003] When using current OLT devices, due to its huge data transmission volume, the electronic components inside the device are under load during actual use, which generates a large amount of heat. In order to prevent the device from overheating, a cooling fan is used to assist in heat dissipation. However, during actual use, dust in the external air can easily enter the device with the airflow generated by the cooling fan, especially in idle interfaces. When the interface is used subsequently, it will cause interface contamination, affecting data transmission efficiency. There are certain shortcomings in its use. For this reason, we propose an OLT device with a VLAN interface. Utility Model Content

By arranging a protective box mechanism in conjunction with the cover mechanism, the air in the protective box mechanism is extracted by the fan, and then the external air is filtered through the first partition and the first filter element and then enters the protective box mechanism to dissipate heat for the equipment body. The device structure is simple, which can prevent the equipment body from operating at high temperature for a long time and improve the service life of the equipment body.
