DAC cable CBO Alcatel-Lucent OS6865-CBL-40 40Gbps 1m

BlueOptics DAC cable CBO Alcatel-Lucent OS6865-CBL-40 40Gbps 1m is a direct attach copper (DAC) passive cable designed for short-range, high-throughput interconnects. The cable provides a 40Gbps link over a 1-metre length and is intended for connecting compatible switches, servers or network devices in rack and data centre environments. Its passive construction targets low latency and stable performance for top-of-rack and aggregation use cases, simplifying cabling and reducing power requirements compared with active optical transceivers.

Advantages

The DAC cable delivers a fixed 40Gbps throughput with minimal signal processing, offering low latency and consistent link behaviour. Its 1 m length is optimized for short-distance connections inside racks or between adjacent racks, which helps to reduce cable clutter. Passive design eliminates the need for separate power or active components in the cable itself, reducing potential points of failure and simplifying installation and maintenance.

Suitable for

• Top-of-rack switch to server connections in data centres
• Aggregation links between nearby switches
• Short-range interconnects in server cabinets and telecom racks
• High-throughput, low-latency links for virtualization and storage traffic

Key specifications

• Data rate: 40 Gbps
• Length: 1 metre
• Cable type: Direct attach copper (DAC), passive
• Typical use environment: short-range rack and data centre interconnects
• Latency: low, passive transmission (no active signal regeneration)

How to use

Insert each end of the DAC cable into the appropriate 40Gbps-compatible ports on the devices being interconnected, ensuring connectors are fully seated. Verify link status on both devices and confirm negotiated speed and link health through device management interfaces. For best results, route the cable without sharp bends and avoid excessive tension; ensure compatibility of the connected equipment prior to installation.

Recommendations

Use this 1 m DAC cable for short, direct connections inside racks or between adjacent racks where 40Gbps throughput and low latency are required. Confirm port compatibility and firmware support on Alcatel-Lucent and other network devices before deployment. Avoid routing near sources of strong electromagnetic interference and maintain bend radii consistent with manufacturer guidance.
