Techtest TT4500 OTDR – Dual Wavelength Optical Time Domain Reflectometer

The Techtest TT4500 OTDR is a multifunctional optical fiber testing device designed for fiber installation, maintenance, project testing, and on-site troubleshooting. It combines OTDR measurement with an Optical Power Meter (OPM), Visual Fault Locator (VFL), light source, optical loss testing, and cable tracking functions in one unit. The TT4500 supports 1310nm and 1550nm dual-wavelength testing and is suitable for checking both standard and short fiber links. Its small blind area helps with short-distance measurements, while the high-performance processor provides quick and smooth operation. A touchscreen and physical keys offer convenient control during field work. Key Features Multifunction Testing: Combines several fiber testing tools in one device. Dual-Wavelength Operation: Suitable for common single-mode fiber measurements. Short-Fiber Testing: Designed to handle measurements where fiber length is limited. Cable Identification: Supports cable tracking and sequence checking. Fast Processing: High-speed hardware helps deliver responsive test operation.
