The Black Box QSFP-H40G-AOC5M-BB is a high‑speed, plug‑and‑play 40‑Gigabit Ethernet active optical cable (AOC) assembly. Using QSFP+ connectors on both ends, this 5‑meter (16.40 ft) AOC delivers exceptional transmission performance over lightweight fiber, making it ideal for rack‑to‑rack, switch‑to‑server, and other high‑bandwidth applications inside data centers.
As a genuine Black Box high‑performance interconnect product, this AOC supports low latency, low power consumption, and reliable 40G connectivity. It’s hot‑pluggable, durable, and standards‑compliant for enterprise‑class network environments.
This 40G QSFP+ AOC uses OM3/OM4 multimode fiber technology with integrated transceivers, housed in a compact flexible cable design. No additional optics or patch cords are required — simply plug into QSFP+ switch or NIC ports for instant 40G connections.
QSFP‑H40G‑AOC series cables are lightweight and flexible compared to passive copper, making them perfect for high‑density rack configurations. They eliminate EMI concerns, ensure longer reach, and reduce installation clutter while maintaining signal integrity in high‑speed infrastructures.
The Black Box QSFP‑H40G‑AOC5M‑BB is engineered for predictable, reliable 40G Ethernet connections across data centers and enterprise networks. Its active optical design ensures low BER (bit error rates) and stable performance under continuous load, making it a dependable interconnect for mission‑critical workloads.
