What is a SFP Module?
A Small Form-Factor Pluggable (SFP) module is a small, hot-swappable transceiver used in data communications and telecommunications networks. SFP modules are widely used to link networking devices such as switches, routers, and network interface cards (NICs) to fiber optic or copper cabling infrastructure. Here are some major features and functionalities of SFP modules.
- Compact Size: SFP modules are tiny in size, enabling for high-density installation in networking equipment. They often have dimensions of 2.5 cm x 1.4 cm x 0.9 cm (length x breadth x height).
- Hot-swappable: SFP modules can be inserted and removed from compatible networking devices without turning off the system. This hot-swappable feature allows for easier installation, maintenance, and upgrades.
- SFP modules are interchangeable, which means they can handle a wide range of optical or copper interfaces by just swapping out the module. This versatility enables adaptability in network design and implementation.
- SFP modules enable optical and electrical interfaces, allowing communication via fiber optic or copper cabling infrastructure. They can support a variety of fiber optic cables, including single-mode and multimode, as well as transmission distances.
