What is an SFP Transceiver Module?
An SFP transceiver module, also known as a mini-GBIC (Gigabit Interface Converter), is a hot-swappable input/output device that connects network switches and routers to optical fiber or copper cables. It acts as a transceiver, converting electrical signals into optical signals for transmission over fiber optic cables, and vice versa for receiving signals.
Features and Specifications
SFP transceiver modules come in various types, supporting different data rates, transmission distances, and wavelengths. The most common types include: 1.SFP: These modules support data rates up to 1.25 Gbps and are widely used for Fast Ethernet and Gigabit Ethernet applications. 2.SFP+: These modules support data rates up to 10 Gbps and are commonly used for 10 Gigabit Ethernet applications. 3.SFP28: These modules support data rates up to 25 Gbps and are utilized in 25 Gigabit Ethernet applications. 4.QSFP/QSFP+: These modules support data rates up to 40 Gbps and 100 Gbps, respectively, and are used for high-speed applications such as data centers and cloud computing.
SFP transceiver modules also come in different form factors, including single-mode and multi-mode options, allowing them to cater to various transmission distances. They support different wavelengths, such as 850nm, 1310nm, and 1550nm, enabling compatibility with different fiber types.
