Active Optical Cable BlueOptics BO070703W10M QSFP56 200GBASE-SR4 Ethernet/Infiniband 10 m

The BlueOptics BO070703W10M is an Active Optical Cable (AOC) with QSFP56 connectors designed for 200GBASE-SR4 links over a 10 metre reach. It integrates optical transceivers into a single cable assembly to provide high-bandwidth, low-latency connections for Ethernet and Infiniband networks. The cable is intended for use in data centre environments, for switch-to-switch interconnects, server uplinks and other short-reach high-speed fabric connections where a QSFP56 AOC form factor is accepted.

Advantages

This Active Optical Cable delivers 200 Gbit/s aggregated throughput using the QSFP56 interface and SR4 optical signalling, enabling dense high-speed links without external transceivers. The integrated design reduces connector count, simplifies installation and helps manage airflow and cable density in rack environments. As an optical AOC, it reduces electromagnetic interference and supports lower power consumption and latency compared with equivalent copper cables at this data rate and distance.

Suitable for

• Data centre switch-to-switch connections over short reach (up to 10 m)
• Server to top-of-rack or spine links requiring 200G bandwidth
• High-performance computing and Infiniband fabrics that accept QSFP56 AOC form factors
• Environments where reduced EMI and improved signal integrity are required

When it may not be suitable

This cable is designed specifically for short-reach 200GBASE-SR4 links and is not suitable for longer multimode or single-mode runs beyond the specified 10-metre length. It also requires network equipment that accepts QSFP56 AOC modules; it will not work with devices that do not support QSFP56 electrical or form-factor compatibility.

Key specifications

• Data rate: 200 Gbit/s (aggregated)
• Connector type: QSFP56 to QSFP56
• Link type: 200GBASE-SR4 (multimode, short reach)
• Length: 10 metres
• Cable type: Active Optical Cable with integrated transceivers
• Applications: Ethernet and Infiniband high-speed links

How to use

Install the cable by inserting each QSFP56 connector into the appropriate QSFP56 port on your switches or servers. Ensure the ports are powered down or follow your equipment vendor's hot-plug procedures if supported. Verify link status via device management interfaces after insertion. Route the cable within rack managers or cable guides to avoid sharp bends and maintain the minimum bend radius specified by the manufacturer. No separate transceivers or fibre patching is required since the optical components are integrated into the cable assembly.

What to consider before purchase

• Confirm that your network devices support QSFP56 AOC connections and 200GBASE-SR4 signalling
• Verify required cable length and ensure 10 m meets your rack or row layout
• Check compatibility statements from your switch or server vendor regarding third-party AOCs

Usage recommendations

For reliable operation, route the cable to avoid tight bends, maintain proper airflow in racks, and monitor link status after installation. Use the cable for short-reach high-bandwidth interconnects where QSFP56 AOC form factor is supported.
