Atmospheric pressure: 70–106kPa
Typical Application Scenarios:
Nuclear island I&C equipment room: centrally deployed in core controlled areas such as the HF building and the 220kV switchyard, it carries massive optical signal aggregation of the reactor I&C system, providing low-loss splicing, dispatching and full-link protection between trunk optical cables and I&C equipment, and completely avoiding the impact of strong electromagnetic interference on critical control signals.
Nuclear power data center equipment room: the high-density LC interface model meets 10G and 400G high-speed transmission requirements, supporting high-bandwidth data transmission for the nuclear power production management system and safety monitoring platform, with over 30% port redundancy reserved to meet expansion needs across the plant’s 60-year full life cycle.
Weak-current rooms of nuclear auxiliary buildings: it centrally manages the fiber links of subsystems such as video surveillance, security access control and environmental monitoring within the plant area, avoiding crossover confusion among links and greatly reducing troubleshooting time.
