Why OTDR is the "Gold Standard" for Fiber Network Maintenance? With the rapid development of 5G, FTTH (Fiber to the Home), and data centers, the stability and performance testing of fiber optic networks have become critical. The OTDR (Optical Time Domain Reflectometer), as a core tool for fiber optic testing, can accurately locate faults, measure loss, and generate detailed link analysis reports. This article will delve into how OTDR works, key parameters, selection guidelines, and real-world applications to help engineers, operators, and network maintenance teams improve fiber testing efficiency.
