7. 2 About guide fiber Proper length of Guide fiber is 100 1 000m it depends on the blind area of OTDR In theory minimum length of guide fiber should be two times longer than attenuation blind area but it should be longer in practice 888 545 1254 www PrecisionRatedOptics com 4 6 Setting Proper Parameters At the first time using OTDR if user chooses some testing parameter which is not suitable to the real condition may cause the bad result User should take Testing range pulse width and wavelength into consideration Setting proper testing range Testing range means maximum display range This parameter will Indicate how long will OTDR display on its screen This range must longer than testing fiber usually we choose range which is 20 longer than testing fiber Take note that testing range should not has large difference with testing fiber Otherwise it will affect the effective resolution and overlarge testing range will result In the generation of huge and useless data see Figure 1 Setting proper pulse width Pulse width and blind area dynamic range are directly related to the maximum length in below picture use ten different pulse width to test one testing fiber The smallest pulse width results in the smallest blind area and the most terrible noise The longest pulse width results in the smoothest curve and almost 1km blind area see Figure 2 It is obviously at the top of testing fiber influence on Pulse wid
