transparent OXC (transparent Optical CROSS-connect) Also known as a photonic cross-connect (PXC).A digital cross-connect (DXC) that can be characterized as optical-optical-optical (OOO), because it performs the switching function without converting the optical signal to electronic format. An opaque OXC requires that the optical signal be converted into electrical format before being switched by the electronic DXC, then converted back into optical format before being placed back on the fiber optic transmission system (FOTS).A translucent OXC is a hybrid that includes both electronic and optical switching modules. See also DXC, OEO, OOO, opaque OXC, OXC, and translucent OXC. |
