Customer message: I bought one of your OTDR meters and the OTDR has stopped working. When I run the OTDR test, with the mode Auto-Test, it doesn’t show the map or splices any more. I spliced a pigtail on to the end of a 20 metre roll of fibre and got no measurement: I did
If the OTDR you bought is with 2 wavelengths, but only one works in good condition, the other one does not work, it is laser problem. See the picture (1550nm laser is with problem). You have to contact our technical service team to repair it. if both two wavelengths do not work, it should be
CPU frequency 1GHz DDR 1G TF card 8G For the OTDR operation, please watch demo video here
The manufacturer FirstFiber Technologies help customers create their own OTDRs with their OTDR core processing coding and powerful hardware design ability. They also sell their own OTDRs, the top 6 are listed as following, FF-980REV (Mini Pro, 9-in-1) FF-980EXP (All-in-1, 12-in-1) FF-980MAS (Enhanced OTDR, 12-in-1) FF-980EXT (new Enhanced OTDR, 9-in-1) 8000MAX (High Accurate OTDR) 990PRO
Some customers complain that their FF-980REV OTDR can not be turned on any more. The problem was often caused by not right operating on the OTDR when they test RJ45 cables. Please do not test RJ45 cables if signals exist in RJ45 cable. To proof, please do as following steps,1) Disassemble the device.2) Press and
The Fundamentals of an OTDR The Basics An OTDR combines a laser source and a detector to provide an inside view of the fiber link. The laser source sends a signal into the fiber where the detector receives the light reflected from the different elements of the link. This produces a trace on a graph
Why OTDR plays an important role in Fiber Testing? Why not use a economic Optical Power Meter to replace with OTDRs? Because the main advantage of using an OTDR is the single-ended test—requiring only one operator and instrument to qualify the link or find a fault in a network. And from the other perspective, OTDR
OTDR (Optical Time Domain Reflectometer) is used for test a fiber cable. By OTDR, users can get these parameters of a fiber, Fiber Length Total attenuation Event List Point Loss Break Location Micro Bending Loss @wavelengths (1310nm, 1550nm, etc) Splitter’s insertion loss Return Loss etc Some modern OTDRs integrates with many other common functions, VFL
The optical time domain reflectometer (OTDR) sends a series of light bursts into the optical fiber for processing test. The way to test is to receive the light signal on the same side of the incoming, because the incoming signal will scatter and reflect back when it encounters a medium of different refractive indexes. The
Most OTDRs have an “auto test” function, but these functions are not foolproof. Most problems with OTDR tests occur when untrained users use the autotest function without having an understanding of how the instrument works, what a good trace looks like and, most importantly, what are the characteristics of the cable plant they are testing
FirstFiber Technologies works on OTDR and Telecom Testig Instruments Development. The mini and pro OTDRs have got reputations from global customers. OEM and tech supports available
