When it finds one, the OTDR creates a display called a "trace" that can be used to identify breaks in the fiber optic cable, splices, connectors and excessive bends. 2019-01-30 The reflection is caused by Fresnel Reflections. If you look out of your window at night, you will see your image on the window as well as what is outside. This is a Fresnel Reflection.

OTDR. The OTDR An Optical Time Domain Reflectometer — “OTDR” for short — is an electronic-optical instrument that is used to characterize optical fibers. It locates defects and faults, and determines the amount of signal loss at any point in an optical fiber.

Every OTDR tech is at some point confronted with a trace like this: What looks like a splice on the trace (a connector would have a reflectance peak) shows a gain instead of the expected loss. This has been a source of confusion for OTDR operators since the instrument was invented. Se hela listan på viavisolutions.com OTDR, the full name of which is "Optical Time Domain Reflectometer". The OTDR depends on two types of optical phenomena: Rayleigh Backscattering and Fresnel Reflections: 1.Rayleigh scattering is intrinsic to the fiber material itself and is present along the entire length of the fiber. 2.Fresnel reflections are "point" events and occur only where the fiber comes in contact with air or another Rayleigh Backscattering is fundamental for OTDR operations, and OTDRs are used to measure end-to-end losses, and discrete losses on Splice and connectors. Backscatter coefficient is a measurement of the amount of backscatter when an OTDR emits one 1 Nano second pulse. In many of my previous articles on fiber optic testing, I have mentioned optical time-domain reflectometers (OTDRs).

OTDR traces have several common characteristics. Most traces begin with an initial input pulse that is a result of a Fresnel reflection occurring at the connection to the OTDR. Following this pulse, the OTDR trace is a curve sloping downward and interrupted by gradual shifts. The OTDR is also commonly used to create a "picture" of fiber optic cable when it is newly installed. Likewise, what is OTDR stands for? Optical Time Domain Reflectometer .

As compared to simple VFL(Visual Fault Location) it is a multifunctional mini computer with Key Board, LCD, Pen, etc. As it is clear from the name Reflectometer, it works on the principle of Reflection. Bi-directional OTDR test provide the speed improvement of the fiber optic test and reliable test report. Traditional bi-directional OTDR analysis completely forgotten to take into consideration because technicians spend in their vans travelling from one end of a cable to the other and then back again to exchange data. Automated bi-directional fast OTDR acquisition and fast report generation by OTDR testing is a very important skill to learn for fibre optics. On OTT’s Certified Optical Fibre Installer (COFI) courses you’ll learn how to use an OTDR properly to measure typical links. The COFI core course is designed for installation and maintenance staff working on core telecom fibre optic networks.

Home; Another place this problem shows up is in splice closures. An OTDR may show a bad splice, but it can actually be a crack or stress point somewhere else in the splice closure. Figure 8.
