An optical fiber tester is a device used to test the performance and quality of optical fiber cables. It can detect various problems in optical fiber networks, such as fiber breaks, bends, splices, and connector problems. It measures parameters like insertion loss, optical return loss, and fiber length to ensure the proper operation of fiber optic systems.
The development of optical fiber testers is closely related to the development of optical fiber technology. As optical fiber networks have expanded and the demand for high-speed and reliable data transmission has increased, the need for accurate and efficient testing equipment has become more urgent. Initially, simple light sources and power meters were used to test fiber optic cables. Later, with the progress of technology, more advanced testing instruments such as optical time domain reflectometers (OTDRs) were developed, which could provide more detailed and comprehensive testing results.
