Working principle of encoder optocoupler
An Optocoupler is a combination of LED and a Photo-diode packed in a single package. As we can see in the below-shown circuit diagram, when a high voltage appears across the input side of the Optocoupler, a current start to flow through the LED. Due to this current LED will emit. An optocoupler, also known as an opto-isolator, is an electronic component that transfers electrical signals between two isolated circuits using light. -
Highway Fiber Optic Cable Testing
The three standard methods for testing fiber optic cabling are a visible light source, power meter and light source, and optical time domain reflectometer (OTDR). IEC 60794 is the international standard series governing the design, construction, and performance verification of fibre optic cables. Published by the International Electrotechnical Commission, it defines the mechanical, environmental, and optical tests that every cable must pass before it can be. There are several methods of fiber optic cable testing, each serving a specific purpose in assessing the cable's performance and reliability: Optical Loss Test Sets (OLTS): This method measures the total light loss in a fiber optic link, simulating the network conditions. As the components like fiber, connectors, splices, LED or laser sources, detectors and receivers are being developed, testing confirms their performance specifications and helps. Intertek offers Fiber Optic Components (FOC) Testing for the safety, reliability and performance of fiber optic components including GR-409-CORE and GR-13-CORE. -
