The fiber adapter is also called a fiber flange, and two ends of the fiber adapter can be connected with fiber connectors with the same or different interface types. When the optical fiber connectors with different interface types are connected, conversion among different interfaces such as FC, SC, ST, LC, MTRJ, MPO, E2000 and the like can be realized.
During engineering implementation and maintenance, it is necessary to know the connection state of the optical fiber adapter (i.e., whether the optical fiber is successfully connected) and whether the optical fiber is in use (i.e., whether an optical signal is passing through the optical fiber). However, since the optical fiber adapter is a passive device, it can only be realized by manual recording in general, which is time-consuming, labor-consuming, and prone to error, and therefore, the maintenance cost is high.

Preferably, the third opening and the fourth opening are circular, and the fixed seat is a cylindrical barrel. Preferably, a protection gasket is arranged between the light-sensing probe and the fixed seat, so that the light-sensing probe can be protected from being damaged difficultly, and the sealing performance can be enhanced to achieve the purpose of dust prevention.
Furthermore, the fixing seat can be arranged on the shell in an integrated forming mode, and can also be arranged on the shell in a detachable mode. For example, when the fixing seat is a cylindrical tube, the lower end of the fixing seat is provided with a thread, and the edge of the fourth opening of the outer shell is also provided with a corresponding thread, so that the cylindrical tube can be fixed at the fourth opening in a threaded connection manner.

Furthermore, the fixing seat can be provided with a light-induced probe or not. When the fixed seat is provided with the photoinduction probe, the optical fiber adapter is an intelligent optical fiber adapter capable of automatically detecting optical path signals; when the fixing seat is not provided with the light sensing probe, for example, a dust plug, the optical fiber adapter can be used as a common optical fiber adapter.
Further, the light sensing probe is sensitive to light with wavelengths of 850 nanometers, 1310 nanometers, 1550 nanometers and the like, and whether an optical signal passes through the optical fiber link can be detected through the light sensing probe.
