HPE Mellanox P26659-B24 200Gb/s to 2x100Gb/s QSFP56 Active Optical Splitter Cable, 15m: This is a 15-meter HPE-branded active optical cable (AOC) that splits a single 200Gb/s QSFP56 port into two 100Gb/s (HDR100) QSFP56 endpoints. Cross-reference: NVIDIA MFS1S50-H015V / 980-9I96H-00H015. The cable uses VCSEL optics and is a fixed-length integrated assembly. This is a refurbished unit.
Engineering Context
The P26659-B24 provides inter-row HDR100 connectivity where passive copper cannot reach. At 15 meters, this AOC enables End-of-Row switching architectures where compute racks are distributed across a wider physical footprint while switches are consolidated centrally. The cable delivers deterministic latency and complete EMI immunity. The source end consumes up to 5W and each endpoint up to 3.5W.
Deployment & Use Cases
Connecting HPE Quantum HDR switches to HPE Apollo/ProLiant servers in different rows. End-of-Row network topologies requiring long-reach high-bandwidth links. HPC clusters where overhead cable tray routing requires extra cable length. Environments requiring fiber optics for EMI immunity.
