Q: LED display is weak, unable to display when turned on?

Is it possible that the LED display data is abnormal due to insufficient battery power and timely replacement of the battery?

It is possible that the connector is faulty, dirty, or locked. Reconnect the connector and clean the sensor.

There is some fluctuation in the output optical power when the machine is just turned on. Please preheat it for 15 minutes before using it. Precautions:

1. Avoid looking directly at the output port during work, as lasers can harm your eyes.

2. If not used for a long time, please use a dust cap to protect the output port.

3. If not used for a long time, please remove the battery in a timely manner to avoid damaging the battery shrapnel.

4. Do not disassemble the instrument by yourself to avoid causing more serious malfunctions.

5. Please clean the dirt with a cotton swab dipped in alcohol.

Q: What is the difference between optical power meters and fiber optic testers?

Optical power meter refers to an instrument used to measure absolute optical power or the relative loss of optical power passing through a section of optical fiber. In fiber optic systems, measuring optical power is the most basic, much like a multimeter in electronics; In fiber optic measurement, the optical power meter is a commonly used meter for heavy loads. By measuring the absolute power of the transmitting device or optical network, an optical power meter can evaluate the performance of the optical device.

There are two types of commonly used fiber optic testers: red light pens and OTDR testers.

1. Red light pen: Indoor short distance single core tail fibers can be polished with a red light pen. The red light pen emits visible light, which is transmitted through optical fibers. When the tail fiber breaks, there will be a phenomenon of "light leakage". By observing with the naked eye, it can be determined whether there is a break in the middle of the short distance optical fiber.

2. OTDR: The full English name of OTDR is Optical Time Domain Reflectometer, which means Optical Time Domain Reflectometer in Chinese. OTDR is a precision optoelectronic integrated instrument made by utilizing the backscatter generated by Rayleigh scattering and Fresnel reflection when light is transmitted in optical fibers. It is widely used in the maintenance and construction of optical cable lines, and can measure the length of optical fibers, transmission attenuation of optical fibers, joint attenuation, and fault location. The distance between the fiber optic disconnection point and the testing point can be tested.

By measuring the absolute power of the transmitting device or optical network, an optical power meter can evaluate the performance of the optical device. By combining an optical power meter with a stable light source, it is possible to measure connection losses, verify continuity, and help evaluate the transmission quality of fiber optic links.

Q: What measurements can optical light source and power meter be used for?

Optical power meters can be used for measuring optical channel attenuation, receiver sensitivity, signal-to-noise ratio, and receiver overload power.

Optical power meter is an instrument used to measure the magnitude of optical power, which can be used for both direct measurement of optical power and relative measurement of optical attenuation. It is an essential basic testing instrument for research, development, production, construction, maintenance, and other departments in fiber optic communication systems.

Q: How to use optical light source and power meter to measure light attenuation?

1. When measuring absolute optical power, just connect the light source and look at the value in DBM in the second row of the screen, which is the optical power value.

2. Measure the attenuation of optical fiber. If you know the luminous value of the light-emitting device, you can directly connect the fiber to be measured, and then subtract the value from the luminous value of the light-emitting device to get the attenuation value of the optical fiber.
