100Gbps High-Speed Connectivity
The AT-QSFP28-SR4 provides a 100Gbps optical networking interface for applications requiring significantly higher bandwidth than traditional 10Gbps or 40Gbps connections.
100G connectivity is particularly useful for modern data center architectures where large amounts of server, storage and application traffic must be transferred between network devices with minimal bottlenecks.
100GBASE-SR4 Technology
The AT-QSFP28-SR4 uses the 100GBASE-SR4 short-range optical configuration. SR4 technology is designed for high-speed multimode fiber links within data centers and other short-distance networking environments.
The SR4 architecture uses multiple optical lanes to achieve aggregate 100Gbps bandwidth, making it suitable for high-capacity data center interconnections.
100-Meter Transmission Distance
The AT-QSFP28-SR4 is designed for transmission distances of up to 100 meters over compatible multimode fiber infrastructure.
This reach makes the transceiver suitable for many data center deployments where switches, servers and network aggregation equipment are located within the same facility.
850nm Optical Wavelength
The SR4 optical configuration operates around the 850nm wavelength, which is commonly used with multimode fiber for short-range high-speed data center communications.
Multimode Fiber Connectivity
The AT-QSFP28-SR4 is intended for Multimode Fiber (MMF) applications. Multimode fiber provides a practical and cost-effective optical infrastructure for short-distance data center connections.
Before deployment, ensure that the installed fiber type, patch cables and optical infrastructure are appropriate for 100GBASE-SR4 operation.
MPO/MTP Connector
The SR4 optical architecture uses an MPO/MTP-style multi-fiber connector for its parallel optical lanes.
Correct polarity, fiber configuration and compatible MPO/MTP cabling are important when installing an SR4 link. Always verify the optical cable configuration before connecting the transceiver.
Data Center Networking
The AT-QSFP28-SR4 is well suited to modern data center environments where high-speed connections are required between switches, servers and aggregation infrastructure.
It can be deployed in high-bandwidth spine-and-leaf architectures, server aggregation networks and other 100G Ethernet environments.
High-Bandwidth Switch Interconnects
100G QSFP28 SR4 transceivers can be used to create high-speed connections between compatible network switches. These links can help increase aggregate network capacity and reduce congestion between network tiers.
Server and Storage Networking
High-speed optical connectivity can be useful for server clusters, virtualization platforms, storage environments and other infrastructure where large volumes of data move between systems.
Actual compatibility depends on the network adapter, switch port, transceiver support, firmware and optical cabling used in the deployment.
QSFP28 Form Factor
The AT-QSFP28-SR4 uses the QSFP28 form factor, a widely used optical transceiver form factor for 100Gbps Ethernet networking.
QSFP28 provides a compact solution for high-density network equipment, allowing multiple high-speed optical ports to be installed within modern data center switches and routers.
Compatibility Considerations
Before purchasing the AT-QSFP28-SR4, verify that the target network equipment supports the specific Allied Telesis transceiver and 100GBASE-SR4 optical standard.
