Solved Uplink And Downlink Terminology

Which switch supports downlink optical ports

An all-optical Ethernet switch provides both optical uplink and downlink ports, and uses optical fibers that feature high transmission speed, large bandwidth, and strong anti-interference capability. They can function as core, aggregation, and access devices on campus networks and connect to upstream and downstream devices. The VIC 1225T module supports copper connectors, copper cables, and switches with copper downlink ports (such as: Cisco Nexus 93108TC-FX switch). CloudEngine S5735-S-V2 series hybrid optical-electrical switches are developed based on next-generation. CloudEngine S5736-S series switches are next-generation standard all-optical GE access switches that provide 24-port and 48-port models, and provide four 10GE ports and one extended slot(optional). This design enables end-to-end optical signal transmission, avoiding the conversion between electrical and optical signals at the switch port level.
