The Keysight E4310A is an Optical Time Domain Reflectometer (OTDR) mainframe designed for testing and troubleshooting optical fiber networks. It analyzes backscattered light to detect faults, measure fiber length, and assess signal loss within optical fiber infrastructure. The mainframe accepts user-exchangeable OTDR plug-in modules that determine specific optical testing capabilities and wavelength performance. Optional interfaces include HP-IB (Option 004) and LAN (Option 005) connectivity. The E4310A has been classified as obsolete by the manufacturer.
