Product Detailed
has visual fault location(vfl) dead zone<5m the hightest sampling distinguish ablity 0.25m, 16k real data sampling poit, LCD

ST3200 OTDR (Optical Time Domain Reflectometer) is an intelligent optical fiber communication tester. This tester is easy to use and portable, which has a 3.5-inch color LCD touching screen. It also possesses events intelligent analysis and more user—friendly operation.

It is an ideal test instrument for the fiber testing and troubleshooting. It can test the length of optical fiber and optical fiber cable attenuation coefficient. It can exactly display the loss distribution curve of the optical fiber and cable as well as the loss between two points and the joint loss. It also can test the distance between two points and the position of joint, fault point as well as breaking point. This tester has VFL (Vision Fault Locating) system. So it becomes convenient to test the fault location of jumper wire.

Ⅱ. Main functions

n    Test the distance between two points and dynamically display the distance between two cursors

n    Test the loss between two points and the loss constant of the optical fiber and cable

n    Test the joint loss

n    Auto-optimization and quick response

n    Search for the event points automatically

n    The function of wave form storage: it can store the wave form data and test condition into the disk and the stored information also can display again.

n    Support the function of copy: it can copy the data file which is built in the internal disk into the U-disk directly.
