In a possible embodiment, a detection device is further disposed in the head cover 140.

The detecting device is used for detecting the optical characteristics of the pin 130 to detect whether the pin 130 is damaged.

Wherein, the detection device integrates a detection circuit and a power supply in advance. When detection device detects, when being about to cover headgear 140 outside inner shell 120, pin 130 inserts detection device, and detection device output detected signal is to pin 130 on to whether this pin 130 appears damaging through the testing result of gathering pin 130 feedback judgement, and then realize monitoring optical fiber splice 100 in real time, and can in time send alarm information when pin 130 breaks down.
