AOC CBO QSFP Active Optical Cable 40G 2m, model AOC-Q-Q-40G-2M-BO

The AOC CBO QSFP Active Optical Cable 40G 2m (AOC-Q-Q-40G-2M-BO) is a 2‑metre QSFP-to‑QSFP active optical cable that supports 40 Gbit/s data rates for short‑reach links. Designed for data centre interconnects and high‑density networking, this cable uses optical signalling to deliver high bandwidth with low latency between compatible QSFP ports. Its compact QSFP form factor allows direct connection between servers, switches and routers without additional transceivers, simplifying rack cabling and reducing power consumption compared to copper alternatives.

Advantages

The active optical design provides stable 40 Gbit/s throughput with reduced electromagnetic interference and improved thermal performance compared with passive copper cables. At 2 metres length it balances reach and rack flexibility for top‑of‑rack and middle‑row connections. The QSFP connector form factor ensures broad compatibility with equipment supporting QSFP/QSFP+ ports and enables hot‑plug installation for minimal downtime.

Suitable for

• Server-to-switch connections in data centres
• Switch-to-switch short‑reach interconnects
• High‑density top‑of‑rack cabling
• Low‑latency storage area network links

Key specifications

• Data rate: 40 Gbit/s aggregate
• Length: 2 metres
• Connector type: QSFP to QSFP (hot‑pluggable)
• Transmission medium: active optical cable (optical fibre)
• Typical use: short‑reach data centre links
• Latency: low, suitable for latency‑sensitive applications

How to use

Install the cable by aligning each QSFP connector with the corresponding port on your networking equipment and insert until the latch engages. Ensure both devices support 40 Gbit/s QSFP links and are powered on; the link should negotiate automatically. Avoid bending the cable beyond its specified minimum bend radius and route it through rack channels or cable management to prevent strain. For hot‑swap operations, unplug one end only after confirming device support for link loss procedures if required by your network design.

Recommendations

Use this 2‑metre active optical cable for short‑reach, high‑bandwidth connections where reduced EMI and lower power dissipation are desired. Verify QSFP compatibility and firmware support on devices before deployment, and maintain proper cable routing to ensure signal integrity and mechanical reliability.
