SFP28 25G LR 10km optical module: a powerful assistant for high-speed data transmission

In today's era of information explosion, efficient and stable data transmission has become an indispensable part of all walks of life. With the rapid development of technologies such as cloud computing, big data, and 5G communications, the requirements for data transmission rate and transmission distance in data centers, enterprise networks, and telecommunications networks are also increasing. It is in this context that the SFP28 25G LR 10km optical module has become a shining star in the field of high-speed data transmission with its excellent performance and wide application scenarios.

SFP28, the full name of which is 25 Gigabit Small Form-factor Pluggable, is an upgraded version of SFP+ and is designed for 25Gbps high-speed networks. The "28" in its name represents its support for 28 Gbps electrical interface (actual transmission rate is 25Gbps), continuing the miniaturization (14mm width) and hot-swappable characteristics of SFP/SFP+, and achieving a higher single-channel rate by optimizing signal modulation technology (such as PAM4) and electrical interface. SFP28 optical modules are widely used in scenarios such as data centers, 5G communications, and high-performance computing. They are core components of 25G Ethernet and some 100G networks (4×25G channels).

SFP28 25G LR 10km optical module is an optical module that supports 25Gbps data transmission rate and a transmission distance of up to 10 kilometers. The "LR" here stands for long-distance transmission, and "10km" clearly indicates the upper limit of its transmission distance. This optical module has an operating wavelength of 1310nm, adopts a dual LC interface, is equipped with a DFB laser and a PIN photodetector, and has a built-in CDR circuit in the receiving channel to ensure stable and reliable data transmission.
