Have you ever noticed that intriguing port on your PoE switch and the distinct cable connector that accompanies it? If not, you're about to discover its significance, especially in the realm of big scale networks and businesses requiring extensive network coverage.
Q: What is the SFP, and what does it mean?A: The SFP port stands for Small Form-factor Pluggable port. It's a compact slot designed for SFP transceivers, allowing the insertion of hot-swappable modules. These modules facilitate the connection of fiber optic or copper Ethernet cables to the switch, commonly used for uplink connections in networks.
Q: What is it used for?A: The SFP port on a PoE switch serves multiple purposes. It's the go-to solution for high-speed data transfer, ranging from 10 gigabit (SFP+) to a staggering 400 gigabit (QSFP 56DD). This port excels in low latency, as evidenced by a meticulously crafted latency chart in microseconds. Moreover, it's the gateway to long-distance data connectivity, with some types, like Type ZX, boasting a maximum reach of up to 80km. Primarily, SFP ports facilitate uplink connections to other switches, routers, or network devices using fiber optic or copper Ethernet cables.
