As used herein, the terms “first,” “second,” “third,” and “fourth,” etc., are used interchangeably to distinguish one component from another and are not intended to indicate the location or importance of a single component.

[0016] like Figure 1As shown, according to an embodiment of the present invention, a portable fiber optic test light source is provided, comprising: a power supply; an FPGA module connected to the power supply, the power supply being able to supply power to the FPGA module; and a photoelectric conversion module connected to the FPGA module and the optical fiber, the FPGA module being able to control the photoelectric conversion module to send optical signals to the optical fiber.

[0017] The photoelectric conversion module can convert electrical signals into optical signals under the control of the FPGA module, providing a light source for fiber optic testing.

[0018] The photoelectric conversion module model can be selected as OYJ2-6003-1CA.

[0019] The fiber optic test light source also includes an indicator circuit, which is connected to the FPGA module and can display the working status of the photoelectric conversion module.

[0020] Since the light used in fiber optic communication is invisible light (wavelengths of 1310nm and 1550nm), the indicator circuit can indicate whether the light source is turned on. Typically, the indicator circuit includes a light-emitting diode (LED) that emits visible light. When the photoelectric conversion module is working, the LED also lights up, thus reminding the user.

[0021] The fiber optic test light source also includes a switch, and the power supply is connected to the FPGA module via the switch.

[0022] The switches mentioned above are usually rocker switches. When using them, you can choose a rocker switch with an indicator light, which can indicate the working status of the rocker switch.

[0023] Preferably, the fiber optic test light source further includes a voltage conversion circuit, and the switch is connected to the FPGA module through the voltage conversion circuit.

[0024] The output current of the power supply needs to be regulated by a voltage conversion circuit to meet the usage requirements of the FPGA module.

[0025] The fiber optic test light source includes a fiber optic interface, and the fiber optic cable is connected to the photoelectric conversion module through the fiber optic interface.

[0026] Before use, connect the pigtail to the fiber optic interface, test the luminous power of the photoelectric conversion module, and observe the working status of the indicator circuit. Then, turn off the photoelectric conversion module and observe whether the display module is turned off correctly.

[0027] When using the device, first insert the standard jumper (SC fiber optic interface) into the fiber optic interface of the equipment, and use an optical power meter to test the loss. Take the test value of this loss as the reference loss of the equipment. When conducting fiber optic loss testing in an environment without mains power, use the equipment to emit light at one end and use an optical power meter to receive light at the other end. Subtract the reference loss from the measured value to calculate the actual loss of the line.

[0028] The power source is a portable power bank, which is connected to the switch via a data cable.

[0029] A 5V / 2A power bank can be used as the power source.

[0030] As can be seen from the above description, the above embodiments of this utility model achieve the following technical effects: improve the convenience of fiber optic testing and shorten the fault handling time.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model.
