If you want to achieve the highest speed and distance in the cabling between two or more switches, without a doubt, the best option is the fiber optic connection and using the SFP or SFP + ports of the switches. Ethernet switch port types define the performance, scalability, and architecture of modern networks. 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. A fiber optic network controlled switch is a handy tool when guiding data traffic in a network utilising fiber optic cables—which offer faster speeds and reduced latency than standard copper cables. Figure 50 on page 83 shows the pinouts. Note: For the IE 2000U model (IE 2000U-16TC-GP) that supports PoE, connector pins 3 and 6 supply +48/+54 VDC and pins 1 and 2 are the DC voltage return lines. Fiber provides: Increased internet signal bandwidth. Most modern fiber-enabled network switches require an SFP transceiver module. Multimode fiber optic switches have emerged as a crucial component, enabling seamless connectivity and efficient data transmission.
