Existing optical fiber curing ovens often experience high temperatures in the center and low temperatures at the edges, resulting in inconsistent curing temperatures for the same batch of optical fiber connectors. Therefore, further improvements are needed. Utility Model Content

This effectively improves the problem of uneven temperature within the curing tank, ensuring consistent curing temperatures for fiber optic connectors cured in the same batch, and improving curing quality. The installation of multiple temperature sensors further enhances the accuracy and reliability of temperature monitoring.

[0011] Preferably, the curing station is provided with a temperature controller for adjusting the heating power of the heating rod, and the temperature sensor is electrically connected to the temperature controller.
