[0016] As Figure 1 shown, according to an embodiment of the present invention, there is provided a portable optical fiber test light source, including: a power supply; an FPGA module, the FPGA module is connected to the power supply, and the power supply can supply power to the FPGA module; a photoelectric conversion module, the photoelectric conversion module is connected to the FPGA module and an optical fiber, and the FPGA module can control the photoelectric conversion module to send an optical signal to the optical fiber.

[0017] The optoelectronic 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 model of the optoelectronic conversion module can be selected as OYJ2-6003-1CA.

[0019] The fiber optic test light source further includes an indication circuit, which is connected to the FPGA module and can display the working state of the optoelectronic conversion module.

[0020] Since the light used in fiber optic communication is invisible light (with wavelengths of 1310nm and 1550nm), the indication circuit can indicate whether the light source is started. Usually, the indication circuit includes a light-emitting diode that can emit visible light. When the optoelectronic conversion module is working, the light-emitting diode is also lit, thus realizing a reminder to the user.

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

[0022] The above-mentioned switch is usually a rocker switch. When in use, a rocker switch with an indicator light can be selected, and the working state of the rocker switch can be indicated through the indicator light.

[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 the 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 is connected to the optoelectronic conversion module through the fiber optic interface.

[0026] Before use, the pigtail can be connected to the fiber optic interface to test the luminous power of the optoelectronic conversion module and observe the working state of the indication circuit. Then turn off the optoelectronic conversion module and observe whether the display module is correctly turned off.

[0027] When in use, a standard jumper fiber (SC fiber optic interface) can be inserted into the fiber optic interface of the device first, and the loss can be tested with an optical power meter. The test value of this loss is used as the reference loss of the device. When performing fiber optic loss testing in an environment without commercial power, one end emits light with this device and the other end receives light with an optical power meter for testing. Subtracting the reference loss from the measured value obtained can calculate the actual loss of the line.

[0028] The power supply is a mobile power supply, and the power supply is connected to the switch through a data cable.

[0029] The power supply can select a mobile power supply of 5V / 2A.

[0030] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: improving the convenience of optical fiber testing and shortening the fault handling time.

[0031] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
