Explore SFP Optical Transceivers

SFP (Small Form-factor Pluggable) and SFP+ modules are compact, hot-swappable transceivers that enable network devices such as switches, routers, and servers to establish high-speed fiber or copper connections. They work by converting electrical signals from the network device into optical signals for transmission over fiber, and converting received optical signals back into electrical signals at the destination. SFP modules commonly support Gigabit Ethernet, while SFP+ modules are designed for higher-speed 10GbE connectivity. WatchDog SFP/SFP+ modules are designed to provide reliable, flexible, and efficient connectivity across enterprise, campus, and data-center networks, supporting different fiber types, transmission distances, and network deployment requirements while enabling easy upgrades and simplified network expansion.
