Optical couplers combine or split light signals between fibers. Couplers merge signals from multiple fibers into one, while splitters divide a single input into multiple outputs. They are commonly made using fused biconical taper (FBT) or planar lightwave circuit (PLC) technologies. Applications include network splitting in Passive Optical Networks (PON) and signal monitoring for detection purposes .
WDM devices combine (multiplex) or separate (demultiplex) optical signals of different wavelengths in a single fiber. Technologies include Thin-Film Filters (TFF) and Arrayed Waveguide Gratings (AWG). WDM is essential for increasing fiber capacity by allowing multiple data streams to travel simultaneously .
Optical isolators allow light to propagate in only one direction, preventing back-reflected light from reaching sensitive sources like lasers. They rely on the Faraday effect and are critical for protecting lasers and amplifiers from instabilities or damage .
Circulators are multi-port, non-reciprocal devices that route light sequentially from one port to the next while blocking reverse transmission. They are used to separate forward and backward signals in fiber networks, enabling efficient signal management .
Attenuators reduce the intensity of optical signals in a controlled manner. They prevent receiver saturation, balance wavelength power, and allow testing of network performance. Types include plug-style, in-line, fixed, and variable attenuators .
Fiber collimators convert divergent light from a fiber into a parallel beam or couple collimated light into a fiber. They are used for precise light alignment between fibers or optical devices and are available for both single-mode and multimode fibers . These six passive optical devices are fundamental in fiber optic communication systems, enabling efficient signal routing, splitting, protection, and wavelength management without requiring external power .
