Cisco QSFP-H40G-AOC3M cavo ottico attivo (AOC) 40G QSFP+ compatibile, 3m (10ft)

For high-density 40GbE links where copper DACs fall short, this FS.COM QSFP-H40G-AOC3M compatible active optical cable delivers a 3-meter reach with the same plug-and-play simplicity as a direct attach cable. It pairs QSFP+ connectors with integrated optical engines, eliminating the need for separate transceivers and fiber patch cords while keeping signal integrity intact across the full 40 Gbps data rate.

Highlights

• 40 Gbps QSFP+ to QSFP+ active optical cable, fully compliant with SFF-8436 and MSA specifications
• 3-meter (10 ft) multimode fiber construction, ideal for top-of-rack to server and switch-to-switch connections
• Hot-swappable design with digital diagnostic monitoring (DDM) for real-time link health and temperature tracking
• Low power consumption under 1.5 W per end, reducing thermal load in dense racks
• PVC (OFNR) jacket rated for data center and enterprise environments; RoHS compliant

In daily use

This AOC behaves like a standard QSFP+ cable but uses light instead of copper, so it avoids electromagnetic interference and supports longer distances without signal degradation. It is coded for Cisco QSFP-H40G-AOC3M compatibility, so it is recognized automatically by compatible switches, routers, and network interface cards. The cable is thin and flexible, making cable management easier in crowded racks, and the pull-tab connectors allow quick insertion and removal without tools.
