The hybrid networking technology of GPON and XGS-PON is adopted to precisely match the different bandwidth requirements of Qilu Hospital in various scenarios.GPON supports 1.244G/2.488G uplink and downlink bandwidth to meet the business needs of pharmacies, billing counters, offices and other scenarios. XGS-PON supports uplink and downlink symmetrical 10G to meet the needs of ultra-high bandwidth scenarios such as CT/MR.The 10G bandwidth improves the reading efficiency by 10 times, and the transmission of thousands of CT slices in seconds greatly improves the efficiency of diagnosis and treatment.The OLT dual link is connected to the core switch. Various protection networking methods such as TYPE B and TYPE C are used between the OLT and the ONU to achieve end-to-end network topology redundancy and fully improve the network at the core and access layers of Qilu Hospital. High reliability.
