Description

technical field [0001] The invention belongs to the field of calibration of bidirectional receiving and receiving optical power of single-fiber bidirectional optical network equipment, and in particular relates to an automatic calibration device for bidirectional receiving and receiving optical power of PON network equipment. Background technique [0002] PON (Passive Optical Network) access network technology is recognized in the industry as the best solution for FTTx, and it is also the main access method of fiber-to-the-home. The scale of the optical network and the number of terminals are huge. This technology can enable multiple users to share a single Root optical fiber, so that no active components are used in the optical distribution network (ODN), that is, no "optical / electrical / optical" conversion is required. This point-to-multipoint architecture greatly reduces network installation, management and maintenance. cost. [0003] In the PON system (GPON, EPON, etc.),...
