An optical cross-connect (OXC) is a network device that switches high‐speed optical signals between fiber inputs and outputs without converting them to electronics. In essence, an OXC uses photonic switching fabric to route wavelength channels from any incoming fiber to any outgoing fiber. Optical switching represents a fundamental technological evolution, shifting data routing from the domain of electrons to the realm of photons, or light.

    In which year were cables replaced by optical cables

    1980s - Global Expansion: By the 1980s, fiber optic cables began replacing copper cables in major communication networks, particularly for long-distance telephone lines and undersea. (Awarded Nobel Prize in 2009) Ethernet was invented at Xerox Palo Alto. Since I was involved in fiber optics starting in the late 1970s, much of this is from personal experiences and memories. Dates, of course, are often approximate, as putting a firm date on the introduction of a new technology is often impossible.
