Cabo ótico ativo CBO AOC-Q-Q-40G-20M-BO QSFP macho–macho 40 Gbit/s, comprimento 20m

AOC CBO AOC-Q-Q-40G-20M-BO active optical cable is a 20-metre QSFP male-to-male link engineered for 40 Gbit/s high-speed interconnects. The cable uses optical transmission to connect compatible QSFP ports on switches, servers and storage devices, delivering low latency and immunity to electromagnetic interference. At 20 m length it bridges equipment racks or connects devices within larger racks while remaining lighter and easier to route than equivalent copper assemblies.

Advantages

The active optical cable provides a stable 40 Gbit/s connection with reduced signal loss over the 20 m span and improved thermal performance compared with copper cables. Its optical design ensures immunity to electromagnetic interference and minimizes crosstalk between adjacent links. The lighter weight and smaller bend radius simplify cable management in dense data centre layouts and help maintain airflow around equipment.

Suitable for

• High-throughput links between data centre switches and aggregation devices
• Interconnects between servers and top-of-rack or spine switches
• Storage area network (SAN) connections requiring 40 Gbit/s bandwidth
• Environments where electromagnetic immunity and reduced weight are needed

Key specifications

• Connector type: QSFP male to QSFP male
• Nominal data rate: 40 Gbit/s
• Cable type: active optical cable (AOC)
• Length: 20 m
• Latency: low (optical transmission)
• Immunity: resistant to electromagnetic interference
• Application: short-reach data centre interconnects

How to use

Ensure both endpoints have compatible QSFP ports and that host devices support 40 Gbit/s QSFP connections. Inspect QSFP ports and cable connectors for dust or damage before insertion. Insert each QSFP connector into the corresponding port until it seats fully and latch mechanisms engage. Route the cable to avoid sharp bends and maintain recommended bend radius; secure it with cable management accessories if needed. Monitor link status on connected devices and verify negotiated speed and link integrity through management interfaces or LEDs.

Recommendations

For reliable performance, keep connectors capped when not in use, avoid exceeding the specified bend radius, and install the cable in environments within the equipment manufacturer’s temperature and humidity limits. Use the AOC for intra-rack and inter-rack 40 Gbit/s links where optical immunity and lighter weight are advantageous.
