'' long-distance box for a passive optical network system in which different parts coexist and method for uplink and downlink light processing with the long-distance box ''

摘要

The disclosure provides a long-distance box and a method for processing uplink/downlink light thereof. The method includes that: the uplink/downlink light (uplink light and downlink light) from different PON systems is split, and the uplink/downlink light from different PON systems is transmitted through different optical paths; and the uplink/downlink light from different PON systems is processed by long-distance boxes belonging to corresponding systems in different optical paths, and then output to the OLTs/ONUs of respective systems. By means of the method provided in the disclosure, a simple and reliable solution is provided for operators to solve the long-distance problem caused by the coexistence of multiple PON systems; furthermore, in the disclosure, modification for the system is slightest, reliability of the system is highest, and an efficiency of the system is highest, so that time and cost are saved for the operators.
