SSDX PON fiber aggregation and pull far equipment is located in the access cable layer between the OLT and splitter, to achieve multiple OLT and splitter between the same route of multi-core optical cable aggregation transmission, PON signal extension to achieve coverage between the OLT and ONU. It can support a variety of splitting ratio PON aggregation and pulling distance requirements. It effectively solves the problems of large fiber consumption, limited coverage capacity of single core, short transmission distance, scattered OLT deployment, high cost and maintenance difficulties.
