SFP transceivers are widely used in various fields due to their miniaturization, hot-plugged, high speed, and multi-protocol support.

The following is a detailed description of their main application scenarios:

Data Centers

The Cornerstone of High-Speed Interconnection

• Server and Switch Interconnection: 10 Gigabit SFP+ modules (10Gbps) are the standard configuration for data center server access switches, supporting high-density port deployment and meeting the high bandwidth requirements of virtual machine migration and storage access. In 25G/100G upgrade scenarios, SFP28 modules (25Gbps) are gradually becoming mainstream.
• Cross-Rack GPU Communication: 400G DR4 modules (single-wavelength 100G PAM4) can improve inter-GPU communication bandwidth, supporting large-scale distributed training.
• Storage Area Network (SAN): SFP modules support the Fibre Channel (FC) protocol, connecting storage arrays and servers, providing low-latency, highly reliable data block transmission.

5G Network

Empowering the Era of Full Connectivity

• Fronthaul Network (AAU-DU Interconnection): The 25G gray light module supports CPRI/eCPRI protocols, meeting the strict synchronization requirements between 5G base station AAU and DU.
• Midhaul Network (DU-CU/CU-Core Network Interconnection): The 100G ZR coherent module achieves 80km repeater-free transmission, reducing the cost of the metropolitan area network aggregation layer.
• High-Definition Video Transmission: Reshaping Media Production and Distribution
• 8K Ultra-High-Definition Live Streaming: The QSFP28 100G LR4 module can carry two 8K RAW video streams with end-to-end latency <1ms.
• Cloud Rendering Collaboration: The 10G SFP+ module supports real-time cloud rendering of 4K/120fps non-linear editing footage, improving remote collaboration efficiency.

Enterprise Networks and Metropolitan Area Networks

• Enterprise Backbone Network: The 25G SFP28 ZR 80KM optical module can serve as a transmission device for the backbone network, supporting the communication needs of large enterprises.
• Metropolitan Area Network Interconnection: Used to connect data centers or key nodes in different locations, building a high-speed, reliable fiber optic communication network.

The flexibility and high compatibility of SFP transceievrs make them an indispensable component of modern communication networks. With future technological advancements, their application scenarios will further expand.
