Detailed Description
AV6419 Distributed Optical Fiber Strain Tester Product Summaries AV6419 distributed optical fiber strain tester can measure strain distribution, loss distribution and Brillouin scattering spectrum at different location of optical fiber simultaneously, and can display 3D traces and multiple distribution parameters. It has the advantages of high strain measurement accuracy, good measurement repeatability, non-destructive measurement via one end, and it has become the indispensable instrument in the field of optical fiber communication and optical fiber sensor (OFS). AV6419 is used widely in the fields of health monitoring of bridge building, dam, tunnel, lofty building, oil well platform and oil pipeline, and also in the fields of forecasting of geological hazard, such as mountain landslide, mud-rock flow and earthquake, and the fields of the intelligent structure monitoring of seaborne naval vessels and aviation aerospace. AV6419 is also used to measuring the strain distribution of optical fiber loop or subsea optical cable in process of development, production and maintaining of fiber-optic gyroscope (OFG) , optical fiber hydrophone and subsea optical cable. Main Features nondestructive measurement through single-end Distribution measurement of Brillouin scattering spectrum width Distribution measurement of optical fiber strain Distribution measurement of optical fiber loss Measurement of Brillouin scattering spectrum Display multiple distribution traces simultaneously 3D display of loss distribution Large screen color LCD display, touch screen operation Built-in visual fault locator (VFL) System software on-line updating, no need to return to factory General Specification - - - - wavelength | 1550nm5nm | Optical fiber type | Single-mode fiber | Maximum dynamic range1 | 15dB | Strain distance resolution | 1m | Distance accuracy | (0.2+2*sample resolution+2*10-5*measurement distance)(m) | Strain measurement accuracy2 | 50(10-20ns) 10(50-200ns) | Strain measurement repeatability | 100 | Strain measurement range | -15000~+15000() | Measurement range | 0.5,1,2,5,10,20,40,80km | Pulse width | 10,20,50,100,200ns | Average time setting | 210~224 | Readout resolution | 0.05m | Sampling points | 20000 | Refractive index setting | 1.00000~1.99999;0.00001step | Measurement frequency span | 1,2,5,10,20,50MHz | Measurement frequency range | 9.9GHz~12.0GHz | Display | 10.4-inch TFT,1024*768 resolution | Interface Language | Simplified Chinese /English | Interface | VGA,RS232C,USB,Ethernet,earphone | Optical connector | FC/APC(conveniently replaced by SC or ST connector) | VFL | 650nm30nm,2mw(Typical);operation mode:CW,1Hz,2Hz | Power Supply | AC power:100 ~ 242VAC(1.5A),50/60Hz | Maximum power dissipation | 100W | Dimensions | 435(W)*230(H)*495(D)mm | Weight | 20kg | Environmental conditions | Operational temperature: 0~+40; Storage temperature: -20~+65 Humidity:5%~90%, no condensation | - - - - 1.

Multiple-Window Display The optical fiber strain at different location, Brillouin scattering spectrum, spectrum width and Brillouin scattering power distribution can be seen by multiple-window display simultaneously. Due to optimized optical path , circuit and digital data processing model, AV6419 can provide with 1m or less spatial resolution. In the right fig , the distance interval between marker1 and marker2 is 0.92m, and the interval between marker3 and marker4 is 0.51m. High distributed stratin measuring acuracy Under condition of 10ns pulse width, The strain measured accuracy of AV6419 BOTDR is achieved about18 at distance of 11km optical fiber . Visual Fault Locator(VFL) AV6419 has built-in visual fault locator (VFL) function, and has three operation modes, such as CW, 1Hz and 2Hz. It can help operators to find conveniently the break location or the position with high optical loss in short-distance optical fiber link close to the instrument. Multiple External Interface AV6419 offers multiple external interfaces, such as USB, Ethernet, RS232C, earphone and so on. It can provide the functions as follows: External USB disc External printer based on USB interface Communication with PC computer Remote control via Ethernet External earphone Typical Application Geologic hazard (landslide) monitoring By laying optical fiber on the important landslide, with the aid of AV6419 optical fiber strain distributed analyzer, we can detect the shift degree of landslide internal rock-soil and detect its tendency real time. When the strain is big, operator can handle it in time by setting appropriate threshold alarm, so this can avoid big loss due to geology hazard. Tunnel health monitoring Oil pipeline monitoring Dam monitoring Power line monitoring Coal mine passageway monitoring Oil well platform monitoring Lofty building health monitoring The right figure shows the successive 10 times strain measurement results using AV6419, from which we can conclude the repeatability of strain measured by AV6419 is excellent. (2)Distributed strain of optical fiber ring In the process of developing and producing of FOG, AV6419 BOTDR can be used to measuring the distributed strain of optical fiber ring of FOG. (3)The calibration experiment of the temperature coefficient of optical fiber under test The relation curve between Brillouin frequence shift and Temperature: The optical fiber under test was G.652 SM.In the upper figures,the left figure shows the measurement trace of temperature range from 30 to 50with the span of 1, and the right figure shows the trace of temperature range from 50 to 90 with the span of 1(below 50) and 5(over 50). According to the left figure, it can be found out the temperature resolution of AV6419 can be 0.5 actually.
