SFP module can be simply understood as an upgraded version of GBIC. With half the size of GBIC module, it can be configured with more than double the number of ports in the same panel. It is a compact, hot-swappable transceiver module for data communications applications in networking and telecommunications.
SFP modules have a standardized form factor and small dimensions, typically 0.55 inches (14 mm) in width and 0.33 inches (8.5 mm) in height. They use LC (Lucent Connectors) or other compatible fiber optic connectors for fiber optic connections. SFP modules also have electrical interfaces to connect to network devices.
One of the main advantages of SFP modules is their hot-swappable feature, which means they can be plugged into and unplugged from equipment without powering down the equipment. This feature makes it easy to install, upgrade, and maintain network devices without interrupting network operation.
SFP modules support a variety of data rates, from 100 Mbps to multi-gigabit speeds, depending on the specific module type. They are widely used in Ethernet, including Fast Ethernet (100 Mbps), Gigabit Ethernet (1 Gbps), and 10 Gigabit Ethernet (10 Gbps) applications.
SFP modules have become the industry standard for optical transceivers due to their small size, versatility, and high data rate support. They offer network design flexibility and support the use of different fiber types and distances, making them a popular choice in modern network environments.
