An SFP (Small Form-factor Pluggable) transceiver module is a compact, hot-swappable device used in networking and telecommunications equipment to convert electrical signals into optical signals and vice versa. Here’s a detailed overview:

Key Features:

• Form Factor: Small, modular design that fits into an SFP slot on network devices such as switches, routers, and servers.
• Hot-Swappable: Can be installed or replaced without powering down the device, allowing for easier maintenance and upgrades.
• Data Rate: Available in various speeds, including 1 Gbps (Gigabit Ethernet), 10 Gbps (10-Gigabit Ethernet), and higher, depending on the module.
• Wavelengths: Supports different wavelengths such as 850 nm (short-range), 1310 nm, and 1550 nm (long-range), to accommodate various fiber optic cables and transmission distances.
• Distance: Designed for different distance ranges, from short-range (up to a few kilometers) to long-range (tens of kilometers).
