[0004] The optical attenuation adjustable connector integrates the functions of the optical attenuator and the connector. It is well known that the optical attenuator and the connector are very important and widely used optical passive devices. According to the requirements of globalization, diversification and integration, various schemes of adjustable attenuation connectors have emerged in the market, but these schemes always have disadvantages such as unstable performance, single function, and high cost.

[0005] The utility model patent "optical attenuator ZL200910203993" realizes adjustable optical attenuation by replacing optical fiber connectors with different attenuation values, so the operation is complicated and requires high skills; and the optical fiber connector contains expensive attenuating fibers, so the cost is relatively high

The end faces of the front light guide part and the rear light guide part are inclined planes, and the return loss value is the largest when the two inclined planes are kept parallel. Parallel at the same time the return loss is reduced accordingly, so there is no guarantee that any attenuation value will maintain a high return loss

In addition, it is necessary to use the driving device to adjust the attenuation, the operation is more cumbersome, and the cost will increase accordingly
