The switch with the most uplink optical ports is

ExtremeSwitching switches offer up to 12 uplink ports, the highest among the examples provided, using combination copper/optical ports.Details on Uplink Optical PortsUplink ports are used to connect a switch to higher-tier network devices, such as distribution or core switches, and carry aggregated traffic from all downstream devices . Modern switches may have dedicated uplink ports or allow any port to function as an uplink, but dedicated uplinks often provide higher speeds and support multiple VLANs efficiently .ExtremeSwitching SwitchesExtremeSwitching switches provide 2, 4, or 12 uplink ports implemented as combination ports, pairing a copper RJ45 port with an optical SFP port . The optical ports allow Gigabit Ethernet uplinks using SFP modules, and the switch supports automatic failover between copper and fiber connections. With 12 uplink ports, these switches offer the highest uplink optical port density among the examples cited.Huawei CloudEngine S5736-SThe Huawei CloudEngine S5736-S series features 48 downlink optical ports and four 10 GE uplink ports . While it provides high-speed uplinks suitable for aggregation, the total number of uplink optical ports is lower than the ExtremeSwitching models.SummaryFor scenarios requiring the maximum number of uplink optical ports, ExtremeSwitching switches with 12 combination uplinks are the top choice. Huawei CloudEngine S5736-S switches provide fewer uplinks (four 10 GE), but they offer high-speed 10G connectivity and all-optical downlinks, making them suitable for high-performance campus or data center networks .
