Product Description

This Dell Q28-100G-SR4-G2 transceiver offers reliable 100GbE connectivity using QSFP28 form factor, commonly used in data centers to connect switches, servers, and storage systems. It operates over multimode fiber with MPO connectors, ideal for short-range links that demand high bandwidth. Network engineers and data center operators often employ this module to enable fast, efficient data transmission within rack or row environments.

Key Features

  • Delivers 100GbE speed via four 25GbE lanes for versatile use
  • Compatible with standard SR4 multimode fiber setups for easy integration
  • Low power consumption tailored for dense data center deployments
  • Supports up to 100 meters over OM4 multimode fiber cables
  • QSFP28 form factor fits modern high-density switch ports

In practice, this transceiver is typically found in enterprise and cloud data centers where high-throughput, short-distance links are critical. It helps maintain efficient network performance while simplifying cabling with MPO connectors. The module plays a key role in scaling network capacity without sacrificing reliability or increasing complexity.


Use Cases

The Dell Q28-100G-SR4-G2 transceiver is primarily utilized within data center infrastructures requiring high-bandwidth, short-distance optical links. Network architects and IT professionals managing server farms and high-performance computing clusters benefit from its ability to deliver scalable 100GbE connectivity while maintaining efficient cabling and port density.

How It's Used:

  • Interconnecting top-of-rack switches in enterprise data centers to support virtualization and cloud workloads.
  • Linking storage area networks (SANs) where low-latency, high-throughput connections are critical for data access and backup operations.
  • Deploying in campus backbone networks for organizations with high internal data exchange demands, such as research institutions.
  • Supporting edge computing nodes that require rapid data aggregation from multiple local sources before sending to centralized data centers.
  • Enabling network segmentation in multi-tenant data centers to provide isolated, high-speed lanes for different clients or applications.

This transceiver optimizes network performance by enabling dense, multi-lane configurations that accommodate growing bandwidth requirements. Its compatibility with multimode fiber and MPO connectors allows for straightforward upgrades and maintenance in established fiber infrastructures, supporting operational scalability without extensive physical re-cabling.
