## Summary description

The BlueOptics OS6560-CBL-300-BL is a 3-meter InfiniBand cable featuring QSFP connectors. It is designed for high-speed data transmission in data centers and networking environments. The cable ensures reliable performance and low latency, making it ideal for connecting servers and switches in high-performance computing applications.

## Long description

The BlueOptics OS6560-CBL-300-BL is a 3 meter QSFP direct attach cable (DAC) designed for short-range high-speed connections in data centres and networking racks. This passive twinax copper cable implements the 40GBase-CR4 electrical interface and uses QSFP-to-QSFP connectors with 30 AWG wiring to provide low-latency links between switches, servers and storage hardware that support 40 Gb/s QSFP connections.
Advantages
This 3m QSFP DAC offers a cost-effective, low-power and low-latency connection option for adjacent-rack or in-rack links. As a passive 40G twinax cable it does not require additional power for the transceiver side, simplifying deployments and reducing heat output. The cable is built to MSA-compliant mechanical and electrical specifications and is tested for compatibility with major hardware platforms that support the matching Alcatel‑Lucent OS6560-CBL-300 form factor.
Suitable for
 Short-range high-bandwidth links between switches and servers
 Top-of-rack and adjacent-rack connections in data centres
 40 Gb/s Ethernet, FCoE, Fibre Channel and InfiniBand applications on short distances
Key specifications
 Cable type: passive twinax copper (Direct Attach Cable, DAC)
 Connector type: QSFP to QSFP
 Link speed: up to 40 Gb/s
 Length: 3 metres
 Wire gauge: 30 AWG
 Compliance: MSA-compliant mechanical and electrical characteristics
How to use
Connect one QSFP connector to the QSFP port of the source device and the other QSFP connector to the target device, ensuring both devices support passive QSFP DACs and the 40GBase-CR4 electrical interface. Route the cable within the rack or between adjacent racks without sharp bends; maintain the manufacturer-recommended bend radius to avoid mechanical stress. No additional configuration is required beyond standard port enabling and network configuration on the connected devices.
Usage recommendations
Use this 3m QSFP DAC for in-rack or adjacent-rack connections where distances are within the specified length. Verify device compatibility with passive 40G twinax DACs and enable the corresponding ports in the device firmware or operating system. Avoid installing in environments with excessive vibration, temperatures outside device specifications, or where electromagnetic interference could affect signal integrity.
