CBO QSFP+ Active Optical Cable BlueOptics BO252503K30M Mellanox MC2210310-030 30 m

The CBO QSFP+ Active Optical Cable BlueOptics BO252503K30M Mellanox MC2210310-030 30 m is a factory-terminated, high-speed optical direct-attach cable engineered for 40 Gb/s links between QSFP+ ports. This 30 metre active optical cable provides transparent, low-latency connectivity for switches, servers and other network devices that support QSFP+ interfaces. It combines optical transceivers and a pre-assembled fiber cable in one unit to reduce the need for separate transceivers and simplify rack-to-rack or within-rack interconnects over short to medium distances.

Advantages

The active optical design delivers reduced power consumption compared with parallel copper solutions and maintains signal integrity over longer reaches at 40 Gb/s. Being factory-terminated eliminates field connectorization and ensures consistent performance and compliance with QSFP+ electrical and optical parameters. The single-cable solution simplifies inventory and installation workflows while providing the low latency required for data centre and high-performance networking environments.

Suitable for

• 40 Gb/s uplinks between switches and aggregation devices
• Server-to-switch connections in data centre racks
• High-performance computing clusters and storage networks
• Short to medium reach interconnects where low latency and power efficiency are required

Key specifications

• Interface: QSFP+ to QSFP+ for 40 Gb/s links
• Length: 30 metres suitable for intra-rack and short rack-to-rack connections
• Type: Active optical cable with pre-terminated fiber and integrated optical transceivers
• Data rate: Supports 40 Gigabits per second aggregate bandwidth
• Latency: Low-latency optical transmission suitable for time-sensitive applications
• Power: Lower power consumption compared with equivalent copper direct-attach solutions

How to use

Install the cable by inserting each QSFP+ connector into the corresponding QSFP+ port on your network equipment until the latch engages. Verify port status and link negotiation on both endpoints through your switch or server management interface. No separate transceivers or field terminations are required; the cable appears as a direct-attached module to supported hardware and typically follows standard QSFP+ hot-plug procedures. For best results, observe proper cable bend radius and avoid sharp kinks during routing.

Recommendations

Use this active optical cable for predictable short to medium reach connections within data centres and network closets. Confirm QSFP+ compatibility and firmware support on both endpoints before deployment, and route the cable to avoid mechanical stress and excessive bends. Keep spare lengths coiled with gentle loops and store unused cables in a clean, dry environment to preserve optical performance.
