Design and implementation of a small AODF

Cross-connection is the only point in the communications field that has not been automated. With the many fibre networks that have been built, there is strong demand from operators for an automatic optical distribution frame (AODF) to reduce operational costs and provide high-level services. From the twisting relationships between the fibre patch cords on the main distribution frame (MDF), the relationship between the input lines and output lines on the MDF is reversed to be perpendicular to each other, and one-dimensional arrays of input lines and output lines (1D to 1D) are formed to construct the model. According to the model, the AODF prototype of the 1D to 1D form was fabricated with the smallest Lucent connector connector and verified through several cross-connect experiments. The prototype designed has a simple structure, a three-degrees-of-freedom Cartesian coordinate robot can meet switch requirements, and there is non-winding between the fibres after multiple cross-connects. Compared to the single-layer and double-layer form tests, the switch process requires multiple hand-over operations, and handovers take a long time in the switch process. Further research is needed to optimise the handover method and greatly improves the switching speed.
