HPE X1E0 400G QSFP-DD SR8 MM850 100m OM4 MPO16/APC Transceiver

Introducing the HPE X1E0 400G QSFP-DD SR8 MM850 Transceiver — a purpose-built, high-performance solution engineered for modern data centers that demand extreme bandwidth, low latency, and scalable, parallel optics. This 400GBase-SR8 transceiver delivers eight parallel lanes of 50 Gbps each, packing incredible density into the QSFP-DD form factor to meet the growing needs of spine-leaf architectures, cloud interconnects, and multi-tenant facilities. Designed for short-reach interconnects, the SR8 module leverages multimode fiber with 850 nm VCSEL technology to achieve reliable links across standard data-center runs, delivering robust performance with minimized power per gigabit, reduced port count, and simplified cable management. Whether you’re upgrading a swath of data-center links or deploying new high-performance fabric, this module is crafted to optimize throughput, interoperate with leading switching platforms, and accelerate your journey to 400G adoption.

• Unmatched density and performance for data centers: The HPE X1E0 400G QSFP-DD SR8 MM850 Transceiver packs eight parallel 50 Gbps lanes into a single QSFP-DD package, enabling true 400G connectivity over short-reach multimode fiber. Its parallel optics architecture reduces the number of fixed cross-connects and simplifies fiber management while delivering consistent, high-bandwidth performance for demanding workloads such as AI training, high-performance computing, and large-scale virtualization. This transceiver is ideal for high-throughput interconnects between switches, routers, and aggregation layers in modern data-center fabrics.
• Short-reach efficiency with OM4 MMF: Engineered specifically for MMF OM4 fiber, the module supports 100-meter links, offering a cost-efficient solution for intra-data-center deployments. The 850 nm laser emission paired with optimized VCSEL technology delivers reliable transmission across standard OM4 runs, while maintaining low insertion loss and strong link robustness even in dense cable environments. This makes it an excellent choice for campus-style data centers, multi-tenant facilities, and dense deployment scenarios where cabling complexity must be minimized.
• MPO-16/APC connectors for pristine signal integrity: The transceiver uses MPO-16/APC connectors designed to maximize optical performance and minimize back reflections. APC (Angled Physical Contact) polishing reduces return loss, improving signal integrity across all eight lanes. This is especially valuable in high-density racks and long-haul interconnects within data centers, where minimizing reflections directly contributes to link stability and consistent 400G operation.
• Plug-and-play compatibility with enterprise networks: Built to integrate with a wide range of leading network devices, the SR8 transceiver adheres to industry-standard QSFP-DD specifications. It delivers a straightforward, plug-and-play upgrade path for existing 400G deployments and is compatible with many vendors’ 400G-capable switches and routers. In environments that require rapid scaling, this module helps reduce downtime and simplifies fleet-wide upgrades, enabling faster time-to-value for new service offerings and workloads.
• Durable design for ongoing reliability: The HPE X1E0 module is engineered for sustained performance in data-center conditions, with robust optical alignment, secure mechanical fit in QSFP-DD slots, and dependable electrical signaling across all eight lanes. This translates into stable throughput, consistent BER performance, and reduced risk of link outages during peak traffic periods. The transceiver is designed to withstand the thermal and mechanical demands of modern data centers, supporting long-term lifecycle value and predictable maintenance planning.

How to install HPE X1E0 400G QSFP-DD SR8 MM850 100m OM4 MPO16/APC Transceiver

• Prepare the workspace and ensure proper ESD protection before handling the transceiver. Verify that your network device (switch or router) supports 400GBase-SR8 QSFP-DD modules and confirm firmware compatibility with HPE X1E0 transceivers.
• Power down the equipment according to your device’s maintenance procedures to prevent any electrical damage during installation. Remove any existing transceiver from the QSFP-DD port only after confirming safety.
• Gently align the transceiver with the QSFP-DD port and insert it firmly until the module seats with a tactile click. Avoid excessive force; if resistance is encountered, power down the device and re-seat to ensure proper alignment.
• Connect the MPO-16/APC parallel optic cable to the transceiver’s MPO interface. Ensure the fiber fiber-harness is correctly terminated with APC connectors and that all eight lanes are clean and free of dust or contaminants.
• Power on the device and verify link status via the management interface. Check for a healthy 400G link, confirm lane alignment, and run basic connectivity tests to validate data-plane performance across all eight lanes. Monitor for any anomalies in link lights or optical indicators.
• Document the installation for future reference, including fiber routing, connector type, and port mappings. If issues arise, consult the device’s interoperability guide and ensure the transceiver’s firmware is up to date and compatible with your network fabric.
