HPE 100Gb QSFP28 Bidirectional 845972-B21 | QSFP28, Enterprise — 845972-B21

Keep 100 GbE links compact and efficient with the HPE 845972-B21 bidirectional QSFP28 transceiver. Designed for enterprise switching and high-density network fabrics, it supports a cleaner fiber footprint than traditional parallel optics by carrying high-speed traffic over duplex fiber. That makes it a strong fit for environments where every strand, port, and patch-panel position has a cost. This module is aimed at teams standardizing on 100 GbE while controlling cabling complexity. Bidirectional optics can reduce the number of fibers required per link, which helps simplify deployment in aggregation layers, data center interconnects, and spine-leaf architectures. For infrastructure teams, that translates into easier cable management and more efficient use of existing plant. As an HPE-branded transceiver, it is intended to slot into supported HPE networking platforms with the compatibility and procurement clarity enterprise buyers expect. When compared with lower-cost optics, the value here is not just throughput — it is predictable integration, reduced fiber consumption, and a form factor suited to dense production networks. Ideal For 100 GbE switch uplinks in enterprise data centers Spine-leaf fabric connections where fiber count must stay low Aggregation-layer links between network switches High-density rack deployments with limited patch-panel capacity Why This Product 1 Uses bidirectional duplex-fiber design instead of higher-fiber-count optics 2 Targets 100 GbE uplinks in dense enterprise networks 3 QSFP28 form factor supports modern high-speed switch ports 4 HPE-qualified optics help reduce compatibility risk
