RJ45 ports serve access-layer copper connections; SFP/SFP+ ports enable flexible 1G/10G uplinks; SFP28 delivers 25G for modern data centers; QSFP+ and QSFP28 support high-density 40G/100G spine–leaf fabrics. They are characterized by numerous ports and high bandwidth, offering greater reliability, redundancy, throughput, and lower latency compared to access and aggregation switches. For a network with over 100 computers, a core switch is indispensable for ensuring stability and high performance. Engineered to aggregate massive volumes of data from distribution switches, it provides ultra-low latency and maximum throughput to ensure uninterrupted routing and packet. A core switch is the primary switch installed at the backbone of a layered or hierarchical network.
[pdf] A combo port, also known as an optoelectronic multiplexing interface, is a photoelectric composite port with two kinds of Ethernet interfaces (RJ45 port and SFP port) on an Ethernet switch. An all-optical Ethernet switch is a network switch whose service ports are entirely optical, meaning every interface uses fiber rather than copper. Port types are limited to two: optical and Ethernet. In other words, it is a compound port that can support two different physical layers and share the same. It's a switch-port planning guide: how to map access / aggregation / core roles to the right port form factors (SFP+/SFP28/QSFP28/QSFP-DD), then choose DAC/AOC/fiber + connectors (LC vs MPO) without creating rework later. They can function as core, aggregation, and access devices on campus networks and connect to upstream and downstream devices.
