With a length of 5 meters, the cable provides flexibility in network design. Whether connecting devices within a rack or establishing links between racks in a data center, the cable's length offers versatility without compromising on performance.


The QSFP-H40G-AOC5M Cisco 5-meter (16.4-foot) active optical cable (AOC) is designed to provide high-performance connectivity for data center environments. The cable is capable of supporting 40 Gigabit Ethernet (40 GbE) data transfer rates, which is four times faster than 10 GbE. This allows for fast data transfer between devices on the network, providing high-bandwidth and low-latency connectivity.

One of the main advantages of using an active optical cable, as opposed to a passive one, is that it has active electronics built into the cable itself, which amplifies the signal and enables longer distances of transmission. This AOC is specifically designed as a direct-attach cable, meaning it connects directly to the QSFP ports on the devices and doesn't require any additional transceivers or optics.

The cable is compliant with industry standards such as IEEE 802.3ba and InfiniBand, which ensures compatibility with a wide range of devices and provides a high level of interoperability. It also supports RoHS, TIA/EIA, UL, and UL OFNP standards for safety and environmental compliance.


The model Cisco 5M 40GBASE Direct-Attach Active Optical Cable is designed to provide reliable connectivity for data center environments.

The active optical cable design of the QSFP-H40G-AOC5M uses active electronics built into the cable itself to amplify the signal and enable longer distances of transmission. This allows for a direct-attach cable, meaning it connects directly to the QSFP ports on the devices and doesn't require any additional transceivers or optics. This design simplifies the cabling and reduces the number of components that can fail in the connection.

The cable is compliant with industry standards such as IEEE 802.3ba and InfiniBand, and it is designed to be RoHS, TIA/EIA, UL, and UL OFNP compliant.
