HPE Mellanox P26659-B22 200Gb/s to 2x100Gb/s QSFP56 Active Optical Splitter Cable, 5m: This is a 5-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-H005V / 980-9I969-00H005. The cable uses VCSEL optics with LSZH (Low Smoke Zero Halogen) jacket and is a fixed-length integrated assembly. This is a refurbished unit.
Engineering Context
The P26659-B22 is HPE's certified interconnect for HDR100 topologies in Apollo and ProLiant clusters. Recognized by HPE iLO management software for telemetry and thermal reporting. The LSZH jacket meets safety requirements for environments with strict fire code compliance. The 5-meter reach enables rack-to-rack connectivity where passive copper DAC cannot maintain signal integrity at 200Gb/s PAM4 signaling.
Deployment & Use Cases
Connecting HPE HDR InfiniBand switch ports to two HPE ProLiant servers with HDR100 adapters. Optimizing port density in HPE Apollo systems using split-port HDR configurations. Safety-critical environments requiring LSZH-compliant cabling. Deployments requiring 5m spans where passive copper signal attenuation is too high.
