Direct Attach Copper (DAC) Cable CBO OS6865-CBL-200 200 cm for Alcatel‑Lucent switches

Direct Attach Copper (DAC) CBO OS6865-CBL-200 is a 200 cm passive twinax cable designed for use with Alcatel‑Lucent switches. The cable provides a fixed electrical connection for short-reach, high-speed ports and is suitable for direct switch-to-switch or switch-to-server links in rack and data centre environments. As a passive DAC, it offers low latency and predictable performance while avoiding the need for separate transceivers.

Advantages

The passive twinax construction delivers high signal integrity over short distances with minimal power draw compared to active optical alternatives. Being plug-and-play, the cable requires no additional configuration or modules, simplifying installation and reducing hardware inventory. Its 200 cm length offers sufficient reach for common rack-to-rack and rack-to-server connections while maintaining a compact, low-profile link.

Suitable for

• Short-reach 10/25/40/50/100 Gbps switch-to-switch connections in data centres
• Direct server uplinks where passive high-speed links are required
• Top-of-rack and middle-of-row cabling in server rooms
• Environments favouring lower power consumption and reduced active optics use

Key specifications

• Connector type: direct-attach twinax passive cable compatible with Alcatel‑Lucent switch ports
• Length: 200 cm (fixed)
• Cable type: passive twinax copper
• Use case: short-reach, high-speed interconnects
• Latency: low, suitable for latency-sensitive applications

How to use

Connect each end of the DAC cable directly into the compatible high-speed ports on the Alcatel‑Lucent switches or into server network interfaces that accept passive twinax. Ensure ports are powered off or follow hot-plug guidelines provided by your hardware vendor when inserting or removing cables. After insertion, verify link status via the switch management interface and confirm negotiated speed and link health.

Recommendations

Install the cable in clean, unobstructed cable paths and avoid sharp bends or kinks that could stress the connectors or cable assembly. Keep the cable length consistent with rack layout to prevent excessive slack or tension. For best results, use passive DACs for short, fixed links within the same rack or adjacent racks and consider optical transceivers for longer distances or where vendor compatibility requires active optics.
