What Is The OXC?
OXC, the full name is optical cross-connect. Like ROADM, OXC is also an optical transmission device that can exchange optical signals between different optical paths. The concept of OXC actually existed as early as around 2000. In a sense, ROADM is a special implementation of OXC, and OXC includes ROADM. From the perspective of traditional architecture, OXC is composed of optical cross-connect matrix, input interface, output interface, management control unit and other modules. The optical cross-connect matrix is the core of OXC. The so-called matrix is actually a "box" with any internal ports interconnected in pairs. We will explain with the architecture of Huawei's OXC equipment. The OXC equipment is mainly composed of optical circuit boards, optical backplanes and optical tributary boards. Generally speaking, each slot of the circuit board corresponds to one direction. After the optical signal enters, it is "disassembled" into N wavelength signals through WS...
