Optical Cross-Connect Circuit Board
An OXC is mainly composed of a optical backplane, optical line boards and optical add/drop boards, and involves key technologies like flexible optical backplane, high-density optical connector, 1×N wavelength selective switch (WSS) and M×N WSS. ROADM (Reconfigurable Optical Add-Drop Multiplexer) can realize multi-dimensional, large-capacity wavelength-level scheduling, has the advantages of low latency and low power consumption, and meets the networking needs of trunk lines, metropolitan areas and data center interconnections. As the. 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. Compared with traditional ROADM based on separate boards and inter-board fiber patch cords, OXC uses integrated interconnections to build an all-optical switching resource pool, achieving highly integrated, fiber. Fraunhofer IZM produced a first concept of such a combined electro-optical circuit board already in 1999 and has continued to make progress in the field.
