What is the difference between indoor cable and outdoor cable? The center of the fiber optic cable is usually a core made of glass. The core is surrounded by a layer of glass envelope with lower refractive index than the core, so that the optical signal into the fiber core is reflected by the claddi

What are active (AON) and Passive (PON) optical networks?Fiber to the Home (FTTH) enables the installation of fiber from a central point directly into the end user's home, providing unprecedented high-speed Internet access. There are two types of systems for implementing FTTH network deployments: AO
