  • Optical Coupler CTR Selection

    Optical Coupler CTR Selection

    Answer: The current transfer ratio (CTR) is an important parameter in optocoupler selection. It is defined as the ratio of the phototransistor output current (Ic) to the LED input current (If), expressed as. The current transfer ratio is a parameter similar to the DC current amplification ratio of a transistor (h FE) and is expressed as a percentage indicating the ratio of the output current (I C) to the input current (I F). The CTR has the following characteristics and is therefore as important as the. An optocoupler, also known as photocoupler or opto-isolator, is a device which can transfer an electrical signal across two galvanically-isolated circuits by way of optical coupling. This protects sensitive parts from high voltages.


  • How to test the OQC of a fiber optic connector

    How to test the OQC of a fiber optic connector

    Simply connect the fiber optic connector to the microscope probe and the test will be done automatically. As the components like fiber, connectors, splices, LED or laser sources, detectors and receivers are being developed, testing confirms their performance specifications and helps. These test procedures assess the physical and functional qualities of fiber optic cables, connectors, and the network as a whole. Key tests include: Effective fiber testing utilizes advanced tools such as Optical Loss Test Sets (OLTS), Optical Time-Domain Reflectometers (OTDR), and Visual Fault. A structured testing methodology allows engineers and procurement teams to confirm that delivered fiber cables comply with design specifications and international standards. Fiber optic testing of a newly installed system not only verifies that the system meets its design requirements, but also creates a performance baseline for all future testing and troubleshooting of t at system. Always inspect before you connect. Cable contamination can also. First step is to make an accurate inspection of the ferrule, using a video microscope.
