SENTER ST3300 1310/1550 OTDR Tester

Telecommunication construction and maintenance CATV construction and maintenance Cabling system Optical components production and research Other fiber-optics projects

Product Details

I. Brief Introduction

As fiber optics plays more and more important role in modern telecommunication and CATV networks, the requirements to the construction, test and maintenance of fiber optics links also become more prominent.

ST3300 is a unique product mainly designed for construction and maintenance of telecommunication and CATV networks. ST3300 can be widely used in engineering construction,maintenance test and emergency repair of all fiber optics related systems. Comparing with a regular OTDR, ST3300 is more compact in size and easier for field use.

   ST3300 has handheld design, compact and lightweight, easy to carry. Event information through TFT color display and data storage capabilities. Through the USB interface, the test data can be uploaded to the PC, to facilitate the post-processing,

archiving and printing.



II. Main Features

-- Hand-held design, compact and lightweight;

-- Anti-seismic, shockproof and appropriate for field operation.

-- Unique hotkey design

-- Starting in 3 seconds measuring immediately  

-- Narrow event blind zone, simple test of fiber patchcord  

-- Automatic and manual test function  

-- High Capacity SD card

-- Low-power design, optical lithium battery or AA-size alkaline batteries

-- Simple, fast, without complex training

-- VFL (Visual Fault Location) function

-- Multiple light outputs, FC/ST/SC exchangeable

-- OTDR Viewer software for data analysis

-- Light alarm function, preventing the device from being damaged by the signal light
