OXC technology is a core component of modern optical transport networks that enables the flexible switching of optical signals between multiple input and output fibers without converting them into electrical form. In essence, an OXC uses photonic switching fabric to route wavelength channels from any incoming fiber to any outgoing fiber. Optical cross-connect (OXC) is a more flexible all-optical grooming mode. In the 1980s, when transmission speeds supported by optical fibers increased from 45 Mbit/s to 2. 5 Gbit/s, carrier networks. Within OTN, one of the most critical building blocks is the Optical Cross-Connection (OXC), a technology that enables dynamic, high-capacity, and protocol-transparent switching of optical channels. Unlike packet switches, an OXC does no packet parsing, queuing, or buffering.
