Optical networks are designed with various optical components, including fiber optic cables, receivers and transmitters, and optical switches. Using optical networking, you can transmit information at light speed, it’s perfect for low-latency connections and covering longer distances. Fiber optic cables are designed with glass cladding, (it’s this cladding that contains the light pulses).
