OTDR Price is getting economical recently, how to get a good test trace from an cost effective OTDR is critical, the following lists is an instruction about how to get good test result. 1. Select the right pulse width, by selecting a longer or shorter Pulse Width, you can control the amount of backscatter level […]
OTDR FAQ (EXFO OTDR, JDSU OTDR, FLUKE OTDR, YOKOGAWA OTDR, ANRITSU OTDR, TARLUZ OTDR, etc This document is prepared for the newbie in fiber optic industry, to share frequently asked question (OTDR FAQ) from my customer, and shred it here. please drop message to me or post comment to me about OTDR FAQ, which will help […]
Insertion loss tests are primarily used to test FTTx PONs (Passive Optical network) during installation. Insertion loss testing may be performed on individual fiber segments as they’re installed (e.g. test feeder fiber from Central Office (CO) to Fiber Distribution Hub (FDH), test distribution fiber from FDH to AP, or test drop fiber from AP to […]
With the technological evolution occurring in data centers, test requirements dramatically changed for the fiber networks that connect mission-critical servers, networking and storage devices. Selecting the proper OTDR to test your network not only strengthens its reliability, but also improves how quickly and efficiently the job is done, as well as documenting the quality of […]
An OTDR sends short pulses of light into a fiber. Light scattering occurs in the fiber due to discontinuities such as connectors, splices, bends, and faults. The OTDR then detects and analyzes the backscattered signals. The signal strength is measured for specific intervals of time and is used to characterize events. The OTDR calculates distances […]
Problem Cause Solution The application displays a message indicating that a “Non-resolved fiber end” event has been found. The fiber under test is too long. Ensure that the fiber under test is shorter than the maximum length the OTDR can measure. The application displays message indicating that a “live fiber error” occurred and the fiber […]
If your fiber optic cable is not properly aligned and/or connected, you will notice heavy loss and reflection. Properly cleaning and connecting optical fibers to OTDR is important, please follow the following steps to clean the fibers and connecting it to OTDR. To connect the fiber optic cable to the port: 1. Inspect the fiber […]
On a transmission network, one cause of insertion loss on a fiber link is macro bending. This is commonly caused by tight installation or handling. As Fiber-to-the-Home (FTTH) networks lead to a significant increase of fiber installation in the last mile, the space constraints become increasingly stringent. This is driving the need for distributions hubs […]
An optical time-domain reflectometer (OTDR) is an optoelectronic instrument used to characterize an optical fiber. An OTDR is the optical equivalent of an electronic time domain reflectometer. It injects a series of optical pulses into the fiber under test and extracts, from the same end of the fiber, light that is scattered (Rayleigh backscatter) or […]
On a data transmission network, one of the main cause for insertion loss on a fiber link is macro bending. This is commonly caused by tight installation or handling. As Fiber-to-the-Home (FTTH) networks lead to a significant increase of fiber installation in the last mile, even G657 fiber are used. the space constraints become increasingly […]
