Application Scenarios of 100G QSFP28 Optical Module

• Data Centers

  • Intra - data Center Interconnection: In data centers, there is a massive amount of data exchange between servers, switches, and storage devices. The 100G QSFP28 optical module can accelerate the connection speed of the Ethernet network, enabling high - speed data transmission between different devices. For example, the 100G QSFP28 SR4 module, which operates at a wavelength of 850nm and supports a transmission distance of up to 100 meters, is suitable for short - distance connections within the data center5. It can be used to connect servers and top - of - rack switches, or to interconnect switches at different levels, improving the overall data transmission efficiency in the data center.

  • Data Center Upgrades: With the continuous growth of data volume, data centers need to upgrade their network bandwidth. The 100G QSFP28 optical module provides a convenient and efficient upgrade solution. It can be seamlessly integrated into the existing network infrastructure, enabling a smooth transition from lower - speed networks such as 10G or 40G to 100G, thereby meeting the increasing demand for data processing and transmission in data centers.

• Telecommunications Networks

  • Backbone Network Transmission: In telecommunications networks, the 100G QSFP28 optical module is an essential device for high - speed data transmission in backbone networks. When telecom data needs to be transmitted over long distances at high speeds, such as between different cities or regions, single - mode 100G QSFP28 optical modules like the LR4 and ER4 are often used. These modules use WDM technology and operate at wavelengths such as 1310nm or 1550nm, which can support transmission distances of 10km to 40km or even longer, meeting the requirements of long - distance, high - bandwidth data transmission in backbone networks.

  • 5G Network Fronthaul and Backhaul: In 5G networks, the 100G QSFP28 optical module is also widely used in fronthaul and backhaul scenarios. For example, in the fronthaul connection between 5G base stations and remote radio units, the 100G QSFP28 optical module can transmit high - speed digital signals between devices with low latency and high reliability. In the backhaul network, it can effectively connect the core network and 5G base stations, ensuring the smooth transmission of a large amount of data generated by 5G services.

• Medical Field

  • Medical Imaging Equipment: In hospitals, equipment such as CT scans, X - rays, and MRIs generates a large amount of high - resolution image data that requires high - speed and stable data transmission support. The 100G QSFP28 optical module can meet this need, providing a reliable communication link for the transmission of medical imaging data between different departments in the hospital, such as from the imaging department to the diagnosis department, enabling doctors to quickly access and analyze patient images, improving the efficiency and accuracy of diagnosis.
