1G SFP optical modules are known as small-package hot-swappable transceivers, which are optoelectronic interface converters that use optical signals to communicate with each other. They're inexpensive, easy to terminate, and play nicely with legacy switches and appliances. The “1G” in “1G Optical Module” denotes a maximum data transfer rate of 1Gbps, which is equivalent to 1,000 megabits. In computer networking, Gigabit Ethernet (GbE or 1 GigE) is the transmission of Ethernet frames at a rate of a gigabit per second. The most popular variant, 1000BASE-T, is defined by the IEEE 802. It came into use in 1999 and has largely replaced Fast Ethernet in wired local networks. Here are the key differences between 1 Gigabit (1G) and 10 Gigabit (10G) ports: 1 Gigabit (1G): 1G ports support a data transfer rate of 1 gigabit per second (Gbps) or 1000 megabits per second (Mbps). This is a common speed for many Ethernet connections, including those found in older network.
