FHO5000 1.4 Connecting the Fiber Before connect fiber to FHO5000,clean fiber end first ,the dust which on the end of connector may damage the optical port or reduce test quality. Procedure: 1. Put connector against the cleaner. 2. Rotate the handle of cleaner. 3.
FHO5000 2.0 Introduction of OTDR 2.1 Purpose of Measurement OTDR shows the back-scatter light power of the optical signal relative to the distance. With this information, the OTDR could measure a series of important information of an optical fiber such as the quality of the line, distance of the line and etc. 2.2 Content of Measurement Event position—a broken point or the end of the tested fiber.
Page 21
FHO5000 Normal Curve A normal trace shows as above, the A mark is a start-peak and the B mark is a end-reflection-peak. The tested trace is oblique, the total loss will become bigger with the increasing of the fiber length. The total loss(dB) divides total length is the average loss(dB/km) of a fiber.
Page 22
FHO5000 Curve with Broken Point If the tested trace is just like the figure shows above, this might be caused by several reasons like: a bad connection between the connector and the lunching port, the optical pulse cannot be launched into the optical fiber or a short distance broken point of the tested fiber from the initial connection and the preset testing distance and pulse width is larger.
Page 23
FHO5000 Abnormal Condition The situation that there is no reflection peak at the end of a trace shows above should be paid attention on. If the distance of the tested fiber is available and the distance shown on OTDR is not equal to the original distance, this shows that the fiber might be broken down or twisted and the bending radius of it is over limited.
FHO5000 2.4 Fundamental of OTDR OTDR——Optical Time Domain Reflector is a high precision optical testing meter that use the theory of Rayleigh scattering and Fresnel reflection. It is widely used in the maintenance, construction and monitoring of an optical line. All the important parameters like fiber length, optical loss, connection loss, broken or twisted point and etc.
Page 25
FHO5000 Formula of the distance: distance = (c/n)*(t/2). Here: c is the light speed traveled in vacuum(2.998*108m/s). T is the delay between launching pulse and receiving pulse. N is the refraction ratio of the testing fiber(specified by manufacturer). When display the whole trace, each point of the trace represents the average value of several sampling points. By zoom in and zoom out function, the value of each sampling point can be got.
FHO5000 2.5 Event Type Start event or non Reflection event End event reflection event The events on trace are all the points that the value of power loss fluctuates abnormally. It usually contains various types of connection and bending, crack, broken and etc. The event points marked on trace with special marks are the abnormal points in a fiber that cause the excursion of a normal trace.

FHO5000 4.5 OTDR Optimizing Tool Guide Fiber Connecting Flange Reflection Event 1.Guide fiber Use an guide fiber to figure out the character of connector. By adding this fiber we could move the fist connector out of the blind area. In the same way we could use this way to figure out the character of last connector. 2.About guide fiber Proper length of Guide fiber is 100~1000m, it depends on the blind area of OTDR.
FHO5000 Setting Proper Parameters 164km test range is too long to the fiber of 7.6km At the fist time using OTDR, if user choose 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.
Page 37
FHO5000 Setting proper wavelength Proceed test with same fiber but different wavelength we will get different result. Longer the testing wavelength is,more sensitive of the bending, in below chart ,first splicing point has bending problem,splicing loss value under 1550nm is bigger than that under 1310nm.

FHO5000 16.2 Terminology Near-end reflection A reflection occurs in the gap between OTDR and the connector for the optical fiber cable. Losses and reflections of the connection points cannot be detected in the section in which this reflection is detected. This section is called a dead zone. Backs cattering light When light propagates through the optical fiber cable, a phenomenon called Rayleigh Scattering occurs due to the nonuniformity of the density or constituents of materials smaller than the wavelength unit.
