HPE Mellanox® P26659-B22 200Gb to 2x100Gb AOC: This high-performance active optical splitter cable (AOC) is engineered for HPE-specific InfiniBand HDR deployments. It facilitates a 200Gb/s QSFP56 connection on the switch side, bifurcating into two independent 100Gb/s (HDR100) QSFP56 endpoints. This 5-meter cable is essential for high-density compute fabrics, offering an integrated optical path for superior signal integrity. This is a fixed-length integrated cable assembly, not a transceiver with a detachable patch cord.

🌐 Engineering Context: The HPE P26659-B22 is critical for HDR100 topologies in HPE Apollo and ProLiant clusters. Compared to equivalent copper solutions, AOC offers lower weight, tighter bend radius, and superior long-term signal stability. The 5-meter reach allows for flexible rack-to-rack cabling while maintaining Deterministic Latency and EMI Immunity, eliminating the risk of electromagnetic interference often found in high-density HPC environments.
🧠 Typical Use Cases
- Connecting an HPE HDR InfiniBand switch port to two HPE ProLiant servers equipped with HDR100 adapters.
- Optimizing port density in HPE Apollo systems by utilizing "split-port" HDR switch configurations.
- Deployments requiring 5-meter spans where passive copper signal attenuation is too high.
- Safety-critical data center environments requiring LSZH-compliant cabling.
✅ Compatible With: HPE InfiniBand HDR Switches, HPE ProLiant DL/ML Series, HPE Apollo Systems, and NVIDIA Quantum QM8700 series switches. (Requires ports configured for native 200Gb HDR operation and MSA-compliant support)
❌ NOT Compatible With: Legacy 40G/56G InfiniBand hardware; standard 100G EDR (NRZ) ports without 50G PAM4 support; standard Ethernet switches not licensed for HDR protocol operation.
🛠️ Installation & Thermal Management
- HPE Ecosystem: This P/N is recognized by HPE iLO and management software, ensuring accurate telemetry and thermal reporting.
- Bending Radius: Maintain a minimum static bend radius of 60mm. Given the 5m length, ensure the cable is properly supported in cable management arms to prevent strain on the optical fibers.
- LSZH Handling: The Low Smoke Zero Halogen jacket is slightly stiffer than standard PVC; avoid kinking during installation to prevent internal glass fracture.
