Record, and show the information of backlight and the relation curve of distance over the display, according to this curve, just can determine that
The position of the length of tested optical fiber, connector and joint, and joint the data such as loss and decay.
The measurement range of OTDR is also the dynamic range of OTDR, and it is defined as:Between top backscattering level and noise
DB it is poor.Measurement range is an important indicator of OTDR, and it determines the ability of long range more than this device measures.Measurement
The size of scope depends on the factors such as the noise of instrument light pulse power, width, wavelength and receiver.Light pulse signal is in light
Decay can be produced when being transmitted in fibre, transmission is more remote, decays bigger, after certain distance is transferred to, by with signal to noise ratio (S/N) too
It is small, cause signal to be distinguished from noise, this factor is determined can the fine distance of light-metering.Dynamic range is big, with regard to energy

What luminous power one was measured is exactly average light power, and the value for measuring is typically small.Surveyed fibre circuit transmission characteristic is done with OTDR
During examination, the size of its mean power is typically only concerned.When the timing of decay one of tested optical fiber circuit, mean power is bigger, its survey
Amount scope is corresponding also big.
The processor of OTDR modules receives control command by Ethernet interface, fiber optic cables is tested, laser
The light pulse signal of respective wavelength is injected to optical fiber, the signal that fibre scattering and bounce back come enters into receiver modules such as couplers
