Thanks to the optical fiber communication, we have been brought to a new internet society. Optical fibers reach more and more families. Optically that is called FTTH (fiber to the home), namely optical fibers installed directly into users’ homes. Besides optical fiber, passive components are also important to optical fiber communication. Many passive optical components are used in FTTH applications. Passive Optical Components In fiber optics, “passive” means the device does not require electrical-to-optical or optical-to-electrical conversion during its operation. Passive components include fiber optical connectors, adapters, attenuators, couplers & splitters, WDM filters & Mux/DeMux, optical switches, etc. First we will talk about optical splitters and filters. Optical Splitters An optical splitter is a device dividing optical power from an optical fiber into several optical fibers. A PLC (Planar Lightwave Circuit) splitter is usually used for fiber branches more ...
