QSFP to QSFP Active Optical Cable, 40GB, 40GBASE-AOC-BCC | Aruba Compatible 7 to 30M

Q: Will this work in place of the Aruba R0Z22A?
A: Yes. The R0Z22A-BCC is designed as a direct replacement for the Aruba R0Z22A. It meets the same 40GBASE-SR4 and QSFP+ MSA specifications, uses the same QSFP+ form factor, and delivers 40 Gbps over four 10 Gbps lanes at 850nm. This cable is plug-and-play compatible with Aruba switches equipped with QSFP+ ports.

Q: Which Aruba switches support this active optical cable?
A: This cable works with Aruba switches that have QSFP+ ports supporting 40 Gigabit Ethernet, including models in the 8360, 8320, and other families with native 40G QSFP+ interfaces. Verify your specific switch model has QSFP+ ports rated for 40GBASE operation; the cable adheres to standard QSFP+ MSA electrical and optical specifications.

Q: What is the difference between active optical cables and passive DAC cables for 40G connections?
A: Active optical cables use integrated transceivers at each end with VCSEL lasers and multimode fibre, enabling longer reach (7m to 30m and beyond) with no electromagnetic interference and lower signal attenuation. Passive DAC cables are copper-based, limited to around 7 metres maximum, generate more heat, and are susceptible to crosstalk in dense deployments. AOCs also consume less power per metre and provide better signal integrity for error-free transmission.

Q: Can I use this cable to connect switches from different vendors, or does it only work with Aruba?
A: The cable adheres to IEEE 802.3ba 40GBASE-SR4 and QSFP+ MSA standards, so it will function with any vendor equipment that supports standard 40G QSFP+ interfaces, including Cisco, Juniper, Dell, and Arista. The electrical signalling, optical wavelengths, and form factor are vendor-neutral. However, some platforms may require host compatibility settings or firmware that recognises third-party optics.

Q: Does this active optical cable support Digital Optical Monitoring (DOM) or diagnostic data?
A: Yes. The integrated transceivers at each cable end support standard QSFP+ diagnostic monitoring via the I2C management interface. You can monitor real-time parameters including optical transmit and receive power per lane, module temperature, supply voltage, and TX bias current. This data is accessible through your switch CLI or network management software for proactive fault isolation and link health assessment.
