- Fiber-Optic Communication
Passive optical components for fiber optic communication process optical signals without requiring electrical power. They support functions such as optical splitting, coupling, switching, filtering, attenuation, and isolation. These components are used in PON systems to distribute optical signals from a single fiber to multiple users, in DWDM systems to combine or separate different wavelengths, and in optical networks to prevent back reflection or adjust signal power levels for stable transmission.
Fiber sensor systems include high-precision interferometric sensing systems and simpler intensity-based sensing systems. Passive optical components, such as optical fibers, Faraday rotator mirrors, splitters, couplers, fiber gratings, and polarization receivers, transmit optical signals to the sensing area and return signals modulated by environmental changes for optoelectronic measurement. These components are immune to electromagnetic interference and can operate in harsh environments, converting changes in physical parameters such as pressure, temperature, acoustics, magnetic fields, rotation, and flow into readable optical information.
