About Optical Power Meter Light Source OTDR Spectrum Analyzer Specifications

That's modulated light, pay attention to the luminous power, if it's not very large, when the light source is not impossible, the pulse width is set to the maximum, the average time is set longer, you will see a large reflection on the OTDR, and the optical power reading may be unstable.

No way! Big is too big to be too big. There is a large pulse width, and when measuring the near line, it will damage the OTDR!. In addition, most OTDRs have the ability to automatically add attenuation based on the received reverse light intensity, so there is no stable luminous power at all. Therefore, it is not recommended to use it as a light source.

Yes, an optical power meter is an instrument used to measure absolute optical power or the relative loss of optical power through a length of fiber.

In fiber optic systems, measuring optical power is the most basic, much like a multimeter in electronics; In fiber optic measurement, optical power meter is a common meter for heavy loads.

The distance measured by the OTDR is incorrect. In addition, it depends on whether the distance measured by the OTDR is close to the actual distance, and there can be an interruption in the middle, and the line is originally broken, of course, the optical power cannot be measured.

If there is no open circuit, and the quality of the line is good. Then consider whether the optical power meter, light source and test method you choose are suitable for your circuit, or whether the optical power meter and light source are faulty. Generally speaking:

The principle of selecting the light source: 1First single-mode light source (can be used for multi-mode light source), 2

Select according to the operating wavelength. 3.According to the distance of the relay section, LD high-stability light source is generally selected.

The longer the line with an output power greater than -6dB (there is now a 7dB light source), the larger it becomes.

Optical power meter selection principle:1According to the transmission distance and the loss of the relay section, the sensitivity of the current power meter is from -40db--90dbm, and the power meter above -75dbm is customarily called the high-sensitivity optical power meter.

For first-class long-distance trunk line projects, high-sensitivity optical power meters should generally be selected. 2.Wavelength:

Generally, there are four gears: 850, 1300, 1310, and 1550.

Use optical power meter and light source to measure attenuation.

Obviously, the fiber optic cable is broken, there is a break point in the middle or one end is not done, and it is known to retest it with OTDR at both ends of AB.

Just don't connect and have data showed? Optical Power Meter Broken?

That can only mean that there is something wrong with your light source or light work.

It must be an OTDR, the optical power meter is only used for power testing within 3 km, and it makes no sense if it is greater than 3 km.
