Features 24 10G SFP+ optical ports and 2 100G QSFP28 ports, with all ports supporting wire-speed forwarding to meet high-density access requirements for 10GE servers. An all-optical Ethernet switch is a network switch whose service ports are entirely optical, meaning every interface uses fiber rather than copper. This design enables end-to-end optical signal transmission, avoiding the conversion between electrical and optical signals at the switch port level. Ethernet switch port types define the performance, scalability, and architecture of modern networks. 10 Gigabit high-bandwidth uplinks, good for long-distance transmission. With enterprise-grade features like power and uplink redundancy, PoE+, and a sensitivity on cost and ease of operations, the Cisco Catalyst PON Series gives you what you need today with the confidence that your.
