Cable CBO BlueOptics CBL-410-BO 10 m QSFP Male–Male 40 Gbit/s

Cable CBO BlueOptics CBL-410-BO 10 m QSFP Male–Male 40 Gbit/s is a copper/active direct attach cable designed for short- to medium-reach, high-speed interconnections. With QSFP male connectors on both ends and a 10-metre length, this cable supports 40 Gbit/s links between switches, servers and other QSFP-equipped network devices. It is intended for use in data centre top-of-rack, aggregation and server-to-server connectivity where reliable, low-latency transmission and simplified cabling are required.

Advantages

The cable provides a compact, single-assembly solution for 40 Gbit/s connections without the need for separate transceivers, reducing component count and simplifying installation. Active copper construction helps maintain signal integrity over the 10 m length and supports low-latency data transfer suitable for demanding networking environments. Its QSFP male–male form factor is compatible with standard QSFP ports, enabling straightforward plug-and-play deployment in compatible equipment.

How to use

Install the cable by inserting each QSFP male connector into compatible QSFP ports on the devices to be linked. Ensure both endpoints are powered down or that hot-plugging is supported by your equipment before insertion, then verify link status via device LEDs or management interfaces. For optimal performance, avoid sharp bends and maintain proper cable routing to prevent strain on connectors. Use compatible port settings on switches and servers to enable 40 Gbit/s operation and, if necessary, configure link aggregation or VLAN settings according to network design.

Recommendations

Use this cable for short- to medium-range 40 Gbit/s connections inside racks and between adjacent racks. Keep cable runs tidy with proper management to preserve signal integrity and avoid exceeding the recommended bend radius. Verify compatibility with device QSFP ports and firmware versions when deploying in mixed-vendor environments.
