Cable CBO CBL-402-BO QSFP macho–macho 2 m 40 Gbit/s

The CBO Cable CBL-402-BO QSFP Male–Male 2 m 40 Gbit/s is a short-reach high-speed interconnect cable for equipment with QSFP ports. With a 2 m length and support for 40 Gbit/s throughput, this BlueOptics cable is intended for direct connections between switches, routers and servers in data center and enterprise networking environments. Its design offers a compact, low-latency link for aggregation, top-of-rack and rack-to-rack connections where a reliable 40 Gb connection is required.

Advantages

This QSFP male-to-male cable provides a simple, low-latency physical link that eliminates the need for additional transceivers in short-distance 40 Gbit/s applications. The fixed 2 m length reduces clutter in rack environments and helps maintain signal integrity for high-bandwidth traffic. Engineered for compatibility with standard QSFP ports, the cable supports dense deployment and straightforward installation in network racks and server cabinets.

Suitable for

• Top-of-rack switch to switch connections
• Server to switch high-speed links
• Rack-to-rack aggregation within data centers
• Low-latency interconnects in enterprise networks

Key specifications

• Connector type: QSFP male to QSFP male
• Nominal length: 2 meters
• Data rate: 40 Gbit/s
• Application: short-reach interconnects for switches, routers and servers
• Typical use environment: data centers and enterprise network racks

How to use

Insert each QSFP connector into the corresponding QSFP port on network devices, ensuring proper alignment and a secure seating. Route the cable within the rack to minimize sharp bends and avoid placing tension on the connectors. Verify link activity and data rate on the connected devices after installation. For equipment with port-specific configuration requirements, adjust device settings or firmware as needed to enable 40 Gbit/s operation.

Recommendations

Keep the cable free from tight bends and excessive mechanical stress, and install it away from sources of strong electromagnetic interference. Use the 2 m length for short intra-rack or nearby rack connections to maintain signal quality; for longer distances choose an appropriate alternative. Check device compatibility with QSFP passive or active cables as required by the network design.
