GAO Tek's OTDRs are used in the field of fiber optics for testing and troubleshooting fiber optic cables. OTDR stands for Optical Time Domain Reflectometer. The OptiFiber Pro OTDR family is the first class of OTDRs that is built with features and usability for both the enterprise network engineers, and cable installers working in both. Optical return loss (ORL): The loss of signal power resulting from the reflection caused at a discontinuity in an optical fiber. Optical link length: The distance between the first network connector and the end of a. VIAVI provides the widest range of OTDR testing tools delivering everything from basic fiber certification to fully automated bidirectional OTDR testing that scales for multi-fiber cable certification. The lightweight and compact SmartOTDR speeds and optimizes field testing of metro and access. The PT-OTDR-100 mini OTDR tester provides a simple to setup and easy to use solution for OTDR testing. This unit will perform OTDR tests, OPM, VFL and laser source functionality for fiber. AFL's Test & Inspection suite offers technicians rugged, easy-to-use tools for inspecting fiber endfaces, identifying faults, measuring optical loss, and managing test workflows. The OTDR shoots a laser light down the optical cable and the laser emits a pulse of light at a specific wavelength, this pulse of light travels along the fiber being tested, as the pulse moves down the fiber portions.
