Keep 100 GbE paths stable across short inter-rack distances with this HP/Aruba compatible active optical cable. The JL277A-ENC is functionally identical to the original JL277A AOC and uses QSFP28 connectors on both ends to deliver 100GBASE connectivity over 10 m. For teams building dense leaf-spine fabrics, it offers a cleaner alternative to bulky copper while preserving the reach needed for adjacent racks and top-of-rack to aggregation links. Active optical cable design helps maintain signal quality at 100 GbE without the thermal and bend-radius constraints that can complicate passive cabling. That matters in production environments where every cable path affects serviceability, airflow, and port access. This model is a practical fit for procurement teams standardizing on Aruba-compatible optics while controlling cost against OEM-branded alternatives. Use it where short-reach, high-bandwidth interconnects need predictable performance and straightforward deployment. The 10 m length supports common data center layouts, and the QSFP28 form factor aligns with modern 100 GbE switching platforms. For infrastructure teams, it is a focused choice: the right reach, the right interface, and the right electrical-to-optical design for dense network builds.
