Determine the configuration principle:
① In order to ensure the compatibility and stability of the equipment, each optical data acquisition system (including the main link optical splitter, the duplicated link optical amplifier, and the duplicated link optical splitter) should be integrated by the same manufacturer;
②Because the optical splitter is a highly integrated, non-modular one-shot device, considering the subsequent scalability, if the configuration is not full, it should be configured according to the full configuration;
③The amplifier should be configured according to the actual scale as needed;
④ In order to save the space of the computer room and facilitate operation and maintenance, the optical splitter racks should be placed uniformly in the computer room;
⑤ Considering the security and stability of the link, the main and backup links are required to be placed independently in sub-racks.
