What is the principle of passive optical devices
The core principle behind their operation is the manipulation of light's path. For instance, the light signal is contained within the fiber through total internal reflection, where light hitting the boundary of the fiber's core and cladding at a shallow angle is reflected back. Optics engineering focuses on transmitting data using light, a method providing the high speeds and vast bandwidth necessary for modern digital life. Passive optical components play a fundamental role within this infrastructure. The enabling components for this development include lasers, modulators, detectors for example, but passive. Optical passive components are the quiet workhorses in fiber systems. Just as a filter in a coffee pot or a sprayer head in a shower just sit there while performing very important functions, passive. A passive optical network is a point-to-multipoint network architecture to serve multiple premises. It allows communication service providers to serve several customers using a single connection.
