A multifunctional following optical cable welding workbench disclosed by the present invention comprises a box body, a workbench surface is arranged at the middle position of the upper top surface of the box body and is connected with an edge at the front side of the upper top surface of the box body via a damping hinge structure, and a fan is arranged on one surface of the workbench surface facing the inner side of the box body. The fan and the workbench surface are arranged parallelly, a temperature sensor and a temperature induction controller are also arranged at the positions close to the left front side of the fan of one surface of the workbench surface facing the inner side of the box body, and a temperature display is arranged on the workbench surface and is connected with the temperature sensor via a conducting wire. The temperature sensor is connected with the temperature induction controller via a conducting wire, the temperature induction controller is connected with a speed regulation joint of a fan motor via a conducting wire and is connected with a storage battery via a conducting wire, and a plurality of radiating holes are also arranged on the workbench surface. The multifunctional following optical cable welding workbench of the present invention enables the temperature of an optical fiber welding machine to be reduced, and the working efficiency of the optical cable welding to be improved.
