HPE 845972-B21 100Gb QSFP28 BIDI 849445-001 AFBR-89BDDZ-HP1 MMF

The HPE 845972-B21 (AFBR-89BDDZ-HP1) is a high-performance 100GBASE-BiDi QSFP28 optical transceiver, designed for short-reach transmission over multimode fiber. It leverages bidirectional (BiDi) technology and a 2×50G PAM4 architecture to deliver 100Gbps full-duplex transmission over a single pair of multimode fibers (OM3, OM4, or OM5). With transmit/receive wavelengths of 855 nm and 908 nm, it supports reach of up to 70 m on OM3, 100 m on OM4, and 150 m on OM5. Optimized for HPE servers and switches, it features full DDM/DOM monitoring and complies with QSFP28 MSA standards.

Product Highlights

100G BiDi PAM4 High-Speed Transmission

Delivers 100Gbps full-duplex bandwidth over multimode fiber with 2×50G PAM4 modulation. Adopts Tx 855nm / Rx 908nm bidirectional wavelengths and fully complies with the 100GBASE-BiDi standard, ensuring stable high-speed transmission performance.

QSFP28 Standard Form Factor & High Density

Adopts industry-standard QSFP28 hot‑pluggable form factor with LC interface, optimized for high‑density deployment on 1U/2U HPE data center switches and servers, saving cabinet space and simplifying port layout.

Multi-Grade Multimode Fiber Coverage

Supports transmission distances of 70m over OM3, 100m over OM4, and 150m over OM5 multimode fiber, perfectly suited for short‑reach interconnections in data center fabric and leaf‑spine architectures.

Single-Pair BiDi Fiber Saving Design

Transmits and receives signals over only one pair of multimode fiber, cutting fiber usage by 50% compared with traditional 4‑lane 100G SR4 solutions, effectively reducing cabling cost and on-site deployment complexity.

HPE Factory Validated Full Compatibility

Factory pre‑tested and pre‑calibrated, natively compatible with HPE ProLiant servers, HPE FlexFabric / Aruba switches and HPE storage platforms, ensuring plug‑and‑play and reliable cross-device interoperability.

Real-Time DDM/DMI Intelligent Monitoring

Integrates comprehensive DDM/DOM monitoring function, continuously tracking transmit/receive optical power, module temperature, supply voltage and laser bias current. Supports remote fault diagnosis and proactive O&M to lower network downtime risk.

Standard Compliance & Environmental Reliability

Meets IEEE 802.3bm, QSFP28 MSA and RoHS compliance requirements. Supports commercial temperature range of 0°C～70°C, delivering stable and consistent operation in long-term data center working conditions.
