The electron current is a strong current and the electrical unit 2 is able to transmit electrical energy.

The sensing unit 3 adopts a sensing optical fiber, the transmission optical signal is used as the basic attribute of the optical fiber, and the sensing optical fiber can transmit the optical signal. The working principle of the sensing unit 3 is that the sensing optical fiber influences and changes the transmission direction of the optical signal in the sensing optical fiber in the process of optical signal transmission, so that the changed optical signal forms a sensing signal in the sensing optical fiber and is transmitted to related equipment, a user can timely and effectively know the optical cable and the surrounding environment, and the optical cable can be well protected.

Optionally, the sensing unit 3 comprises a sensing fiber and a coating. The coating is coated on the outer surface of the sensing optical fiber, and the coating is configured to protect the sensing optical fiber. The coating can effectively prevent the light beam in the sensing optical fiber from leaking out, and can well ensure the transmission of optical signals in the sensing optical fiber. The coating is also used for transmitting the change of the external environment, so that the optical signal in the sensing optical fiber is correspondingly changed to form the sensing signal to be transmitted in the sensing optical fiber.

The sensing fiber comprises a fiber core and/or a sensing optical core, and is configured to generate a sensing signal and transmit the sensing signal. The sensing optical fiber can be a sensing optical core or a fiber core, and the sensing optical core and the fiber core can be connected to form the sensing optical fiber. The sensing optical fiber is used for sensing the change of a magnetic field, gas, temperature, humidity and pressure around the optical cable, so that the optical signal in the sensing optical fiber changes correspondingly to form a sensing signal which is transmitted in the sensing optical fiber. The optical signal in the sensing fiber may change according to the change of the magnetic field around the optical cable, or according to the change of the ambient temperature, or according to the change of a plurality of ambient environmental parameters, to form a plurality of sensing signals. For example, if a fire occurs around the optical cable, the ambient temperature of the optical cable is abnormal, and the user monitors the temperature sensing signal of the sensing optical fiber, so that the optical cable can react quickly, and serious safety accidents can be reduced or even avoided.

Optionally, the electrical unit 2 includes a conductor configured to transmit electron flow, the conductor is a metal conductor, the metal conductor is made of a metal conductive material, the conductor may also be a non-metal conductor, the non-metal conductor is made of a non-metal conductive material, and the metal conductor includes one or more metal wires.

The metal conductive material can be a carbon nano graphene metal conductive material, namely, the metal conductive material is formed by mixing carbon nano graphene and a metal material, and the carbon nano graphene material can also be formed by penetrating between molecules of the metal material. The non-metal conductive material can be a carbon nano graphene material and is used for transmitting electron flow to conduct electric energy. The electrical unit 2 further comprises an insulating layer which wraps the conductor and protects the conductor.

The sensitive material is used for sensing the change of magnetic field, gas, temperature, humidity, pressure and the like around the sensing optical fiber, so that the optical signal in the sensing optical fiber is changed. Further, the sensitive material comprises sensitive particles, the sensitive particles change along with the change of the surrounding environment, the change of the sensitive particles causes the change of the optical signal in the sensing optical fiber, and the changed optical signal forms a sensing signal. For example, the sensing fiber may be made of a plurality of sensitive materials to sense a plurality of environmental change factors, so as to form a plurality of sensing signals to form a sensing current in the sensing fiber, so as to better monitor the surrounding environment of the optical cable.

Optionally, the sensing unit 3 further comprises a sensing cladding, which is coated on the outer surface of the sensing fiber. The sensing envelope is used to sense changes in the coating and the external environment. For example, when the current, voltage, temperature, pressure, or vibration of the electrical unit 2 changes, the coating of the electrical unit 2 changes, and the sensing cladding comes into contact with the electrical unit 2, and the sensing cladding changes accordingly, thereby causing a change in the optical signal of the sensing fiber. Meanwhile, the sensing unit 3 can also sense the light intensity and the light spectrum change of the light unit.

Optionally, the light unit 1 and the sensing unit 3 are arranged inside the electrical unit 2 to constitute a built-in optical cable.
