You must know about weak current network operation and maintenance:
In this issue, we will share with you the "Five Common Types of Optical Modules".
The following is an introduction to these concepts:
SFP
Definition: Small Formfactor Pluggable, or small form factor pluggable transceiver, is a small pluggable module used for optical fiber communications.
Features: It has a small size, usually uses an LC type optical fiber interface, supports hot-swappable function, and is easy to install and replace. It can realize the conversion between optical signals and electrical signals, and is widely used in network equipment such as Ethernet and optical fiber channels. The speed can generally reach 1Gbps or 2.5Gbps.
SFP+
Definition: Small Formfactor Pluggable Plus, an enhanced version of SFP.
Features: Similar to SFP in form factor, SFP+ is mainly used for higher data rate transmission, usually supporting 10Gbps Ethernet applications. It uses more advanced signal processing technology and optical components to achieve high-speed and stable data transmission, while maintaining the same small package size and hot-swappable characteristics as SFP.
SFP28
Definition: Small Form factor Pluggable 28, a small pluggable optical module based on the 25Gbps Ethernet standard.
Features: It can provide a data transmission rate of 25Gbps, meeting the growing demand for high-speed networks, such as server interconnection within data centers, high-speed storage networks, and other scenarios. SFP28 is compatible with SFP and SFP+ in terms of physical size and electrical interface, making it easy to upgrade and replace existing network equipment.
QSFP+
Definition: Quad Small Form factor Pluggable Plus, an enhanced version of QSFP.
Features: QSFP+ further improves the data transmission rate and performance based on QSFP. Its rate per channel is usually 10Gbps or higher, and through parallel transmission of four channels, it can achieve a data rate of 40Gbps. QSFP+ modules also support hot-swap functions, which facilitates the upgrade and maintenance of network equipment.
QSFP28
Definition: Quad Small Form factor Pluggable 28 is a four-channel small package pluggable optical module based on the 25Gbps Ethernet standard.
Features: The data transmission rate of each channel of QSFP28 is 25Gbps, and a data transmission rate of 100Gbps can be achieved through four channels. It adopts more advanced optical and electrical technologies to meet the needs of high-speed data transmission, while maintaining compatibility with the QSFP series modules. It is suitable for scenarios with high requirements for high-speed network bandwidth, such as data centers and cloud computing.
The following is a summary of the port rates corresponding to these module types:
SFP: Commonly 1Gbps or 2.5Gbps.
SFP+: Supports 10Gbps.
