Xinwei Technology ** is around 32000-45000 and is mostly small and portable (this is our domestic brand).

When I searched for it, I mostly found it from one place, so it was relatively individual, but the average ** of this thing can be seen

Also, you have to be clear, "**" is "**"!

Brand I know Amway, Taiyu, as for the model and **. If you're doing this, it shouldn't be hard to find, and the software prospects should be good.

Domestic research in these areas should not be as good as that of developed countries such as Europe and the United States.

Now the OTDR is all Chinese manuals, you can look at it before use, that is, you don't understand too much, it doesn't matter, you can use automatic testing, OTDR will automatically select the corresponding parameters according to the length of the fiber. Once you've been using it for a while, use manual testing to work.

What brand of OTDR do you use, you can contact me I do Canada EXFO OTDR (Canada EXFO Level 1**) 010-62021275

2.Connect the optical fiber connector (refer to the following terminal introduction)3Depending on the wavelength and refractive index, the OTDR is set for mode selection, wavelength, distance (set automatically first, then set according to distance), pulse width, high resolution, and test time.

4.Start the OTDR to start the measurement. During the measurement, the connector cannot be unplugged, and the eye cannot see the end union of the optical fiber.

According to different optical cables, test the length of the optical cable, the attenuation coefficient, the average loss, the total loss, the loss and attenuation coefficient of any two points, the loss of the movable joint and the melting point loss, etc., record the measurement data and calculate, in order to reduce the error, two-way measurement is required.

6 6 Print the data curve and analyze the curve.

Oh, this is more difficult to explain clearly, generally you have to choose a good number of kilometers, first know how many kilometers your fiber optic cable is, and then set the number of test kilometers, and the number of tests, press the start on it, there are breakpoints, divergences or large attenuation points can be displayed, and now they are all fools, and you can understand at a glance.

Just make a material, use the ordinary one, if it is a rush repair, it is best to import the machine. Communicate with each other

Need fiber optic cable contact me, our family is a manufacturer of fiber optic cables,

EXFO Canada, contact me specifically.

optical time domain reflectometer, Chinese means optical time domain reflectometer.

It is mainly used in the maintenance and construction of optical cable lines, and can be used to measure the length of optical fibers, the transmission attenuation of optical fibers, the attenuation of joints and fault location.

Abbreviation of optical mode where OM1 refers to the traditional M multimode fiber, OM2 refers to the traditional 50 125 M multimode fiber, and OM3 refers to the new 10 Gigabit multimode fiber.

OTDR is a precision optoelectronic integrated instrument made by using the backscattering caused by Rayleigh scattering and Fresnel reflection when light is transmitted in the optical fiber, which is widely used in the maintenance and construction of optical cable lines, and can be used to measure the length of optical fibers, transmission attenuation of optical fibers, joint attenuation and fault location.

As long as there is an optical line, OTDR will be used, and it is mostly used for engineering acceptance and ordinary line testing.

It is mainly used in communication engineering.

( x distance + sampling resolution) m This is EXFO's error. The other devices are a little worse than this.

This is actually difficult to verify accurately, because the length and refractive index of the optical fiber are not very accurate.

Usually don't think about the error of the instrument, just think of it as accurate.

After all, OTDR is an auxiliary testing tool, which generally helps us make judgments, and finally we need to use personnel to make comprehensive judgments. 41 OTDRs are good.

The short-distance test is not accurate, and the error you are talking about is no more than 1m. The longer the distance, the more accurate,

Depends on what kind of OTDR you're using

OTDR is a timing pulse timing measurement, and OFDR is measured by the swept frequency signal of a tunable laser, and the measurement result is obtained through the built-in algorithm.

Ten meters or so, while OFDR can reach the micron level. OTDR is generally used for long-distance optical fiber and cable network testing to roughly locate engineering faults, while OFTR is generally used for device-level fault location with ultra-high accuracy. At present, OFDR only has products made by Luna in the United States (you can find me if you have ideas). OTDR has both domestic and foreign production.

Is there an ofdr, OTDR I use the 6416 of the 41 institutes, I still understand a little bit.

OTDR I do CLP 41 here, OFDR? Haven't heard of it.

It is the end of the fiber being tested, from which the length of the fiber can be determined. Usually there is a strong reflection peak on the curve at the end, and if the middle part of the fiber is damaged and broken due to external force, the reflection will be weakened accordingly, and this experience can be used to determine whether the fiber is faulty.
