HPE 100GbE QSFP28 LC DR1 500m Transceiver

The HPE 100GbE QSFP28 LC DR1 500m Transceiver is engineered for data centers and enterprise networks that demand scalable, high-performance interconnects. This 100 Gigabit Ethernet module leverages the compact QSFP28 form factor with an LC duplex connector to deliver efficient, low-latency connectivity between compute nodes and switch fabrics. Ideal for spine-leaf architectures, data-center interconnects, and high-density top-of-rack deployments, this transceiver is designed to simplify cabling while maximizing port density and network reliability. With a 500-meter reach on single-mode fiber (SMF) and a 1310 nm operating window, it enables robust longer-distance links without extensive mid-span infrastructure, helping you optimize both performance and total cost of ownership.

• High-bandwidth, low-latency 100GbE connectivity: This transceiver enables 100 gigabit-per-second data transfer, supporting bandwidth-hungry applications such as high-performance computing, AI workloads, virtualization, and large-scale storage networks. Its optimized QSFP28 design minimizes signal loss and allows for dense aggregation in data center cores, spine-leaf fabrics, and multi-hop uplinks, improving overall network efficiency and application performance.
• QSFP28 form factor with LC duplex connector: The compact QSFP28 package delivers 4×25 Gbps lanes that aggregate to 100Gbps, while the LC duplex fiber connector ensures compatibility with standard single-mode fiber cabling. This combination balances port density and fiber management to optimize rack space, cabling simplicity, and ease of maintenance in densely packed data centers.
• 500-meter reach on single-mode fiber (SMF): Designed for data-center interconnects and campus networks, the DR1 specification supports longer distance links without mid-span repeaters. The 1310 nm wavelength provides efficient transmission over SMF with low attenuation, delivering stable, reliable performance for inter-rack and cross-data center deployments.
• Digital Diagnostics Monitoring (DDM) and reliability: Integrated DDM support provides real-time health data, enabling proactive monitoring, faster fault isolation, and predictive maintenance. This translates to higher uptime, easier capacity planning, and more predictable performance as your network grows or undergoes upgrades.
• Energy-efficient, hot-swappable design for easy deployment: The transceiver is built for data-center environments, prioritizing energy-efficient operation and hot-swappability. In supported configurations, you can swap modules without powering down the entire system, reducing maintenance windows and improving operational continuity during upgrades or scale-outs.
