What is the sensing principle of fiber optic sensors
A fiber optic sensor measures a physical quantity by modulating the intensity, spectrum, phase, or polarization of light traveling through the optical fiber system. It's a device that converts light rays into electronic signals. This signal can then be measured by an instrument or interpreted by a user. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of time. Heating the material enables the trapped states to interact with phonons and decay into lower-energy. Optical fibers provide sensing solutions for many types of applications and environments with high performance.

Single-mode dual-core fiber optic splitting principle
At its core, a fiber optic splitter relies on the principles of light reflection, refraction, and waveguiding to divide signals. A fiber optic splitter is a passive optical component that divides a single incoming optical signal into two or more outgoing signals, or combines multiple incoming signals into one. Unlike active devices (which require power), splitters operate without electricity, relying solely on the physics of. The secret lies in fiber optic technology, and understanding the basics—1-core, 2-core, Single Mode (SM), and Multi-mode (MM)—is key to mastering this field. 2-core o In optical modules, "core". Single fiber modules (BiDi) use one fiber for both transmitting and receiving data. They are easier to set up and give steady communication. They use a thin fiber. A fiber broadband provider typically determines and overall split ratio for the network, such as 1x32 or 1x64, and uses combinations of splitters to meet that ratio with each PON port. 1x32 splits were common in North America for G-PON architectures.
