Designed to integrate seamlessly with HPE StoreFabric Ethernet hardware, Active Optical Cables and Direct Attached Copper cables, it offers a reliable, low-latency solution for high-bandwidth workloads, including cloud, virtualization, AI accelerators, and large-scale storage networks. Whether you’re upgrading a single uplink or fabric, this transceiver is built to support demanding workloads while simplifying your cabling strategy thanks to LC connectors and a compact QSFP28 package.

• High-performance 100G over MMF: The transceiver uses SWDM4 technology to carry four wavelengths simultaneously, enabling a robust 100 Gbps link over standard multi-mode fiber. This approach reduces fiber count and simplifies data-center cabling while preserving the low latency and high bandwidth required by modern workloads.
• QSFP28 form factor with LC connector: Designed for hot-swappable insertion into QSFP28 ports on switches and routers, the module utilizes an LC duplex fiber interface, supporting streamlined integration into existing 100G networks and storage fabrics. The compact enclosure minimizes rack space while maximizing port density.
• Ideal for HPE StoreFabric ecosystems: Built to complement HPE StoreFabric Ethernet Transceivers and related cabling solutions, this transceiver aligns with enterprise-ready reliability, interoperability, and performance across HPE’s data-center fabric products, helping to simplify management and maintenance.
• Support for short-range deployments: With a reach of up to 100 meters on MMF, it’s perfectly suited for top-of-rack to aggregation-link connections, spine-leaf architectures, and inter-rack hops where high-speed links must cover moderate distances with minimal signal loss.
• Diagnostics and reliability features: The transceiver supports essential monitoring capabilities and robust build quality to help operators identify link health, track transmit power, and diagnose performance variations, contributing to proactive maintenance and reduced downtime.

how to install HPE 100Gb QSFP28 LC SWDM4 Multi-mode 100m Transceiver

• Before installation, verify that your switch or network device supports QSFP28 100G SWDM4 transceivers and that MMF cabling is appropriate for the link length and fiber type (OM3/OM4 MMF recommended for 100m SWDM4). Check vendor interoperability notes and ensure the host port is configured for 100G operation.
• Power down the device only if required by your equipment’s hot-swap guidelines, or follow the vendor’s recommendations for hot-swapping QSFP28 modules. Ground yourself to prevent electrostatic discharge and handle the transceiver by its edges.
• Remove the existing transceiver (if present) carefully and inspect the QSFP28 port for any debris or damage. Align the new HPE SWDM4 transceiver with the port, ensuring the connectors are oriented correctly. Gently slide the module into the port until it seats securely with a click.
• Connect the MMF fiber to the LC duplex connector on the transceiver, using the appropriate fiber type (OM3/OM4) and ensuring clean, pristine connectors. Do not bend fibers beyond recommended bend radii, and avoid excessive tension on the fiber patch cords.
• Power up the device and verify link status in the switch’s port configuration interface. If the link does not come up immediately, re-seat the transceiver or swap the fiber patch cord to rule out a fiber- or connector-related issue. Use any built-in diagnostics to confirm transmit power, receive power, and optical signal integrity.
• Optionally enable or check Digital Diagnostics Monitoring (DDM/DOM) values in the switch if supported, to monitor temperature, voltage, laser bias, and optical power in real time. Keep an eye on performance metrics after initial deployment to ensure stable operation under your typical workload.
• Document the installation for change control and update network diagrams. Confirm that the transceiver is operating within the expected parameters and that the 100G link maintains the required bandwidth and latency targets for your applications.

Frequently asked questions

• What is SWDM4 and why use it? SWDM4 stands for Short Wave Division Multiplexing with four wavelengths. It enables 100G transmission over standard multi-mode fiber by multiplexing four optical channels, reducing fiber count and simplifying cabling in data-center fabrics while delivering high-speed performance over short reaches.
• What fiber type and connectors does this transceiver use? It uses multi-mode fiber (MMF) with LC duplex connectors. This combination is common in data-center environments and works well with OM3/OM4 MMF cabling for 100-meter links.
• Is this transceiver compatible with all 100G switches? It is designed to integrate with HPE StoreFabric Ethernet ecosystems and associated cabling solutions. Compatibility with non-HPE devices depends on support for SWDM4 100G MMF transceivers and vendor-specific interoperability. Always verify switch compatibility before deployment.
• What monitoring options are available? Many HPE transceivers support Digital Diagnostics Monitoring (DDM/DOM). When used with compatible switches, you can monitor transmit power, receive power, temperature, and other parameters to help maintain link reliability and performance.
• Can I use this transceiver for longer distances? This model is intended for MMF reach up to 100 meters. For longer distances, you would typically need different fiber types, different transceivers, or a 200G/400G solution designed for extended reach, depending on your network design and equipment capabilities.
• How do I know if SWDM4 is the right choice for my deployment? SWDM4 is advantageous in data centers where fiber density matters and you need to maximize port count while achieving 100G. If your switches, uplinks, and cabling plan support SWDM4-based 100G MMF links, this transceiver can provide a compact, high-performance option for short-range interconnects.
