What is sfp port?

SFP, which stands for Small Form-factor Pluggable, is a compact and hot-swappable transceiver module used in networking equipment such as switches, routers, and network interface cards.

SFP ports are commonly used to connect networking equipment to fiber optic or copper cabling for high-speed data transmission. They support a variety of different types of optical or copper interfaces, including Gigabit Ethernet, 10 Gigabit Ethernet, Fiber Channel, and SONET/SDH.

SFP modules can be easily inserted into and removed from SFP ports without powering down the device. This hot-swappable feature allows for easy upgrades and replacements without interrupting network operations.

SFP ports typically support data rates ranging from 100Mbps to 10Gbps, depending on the specific module being used. They are widely used in enterprise and data center networking environments to provide flexible and scalable connectivity options.
