Passive DAC cable CBO CBL-0349L-BL 5 m SFP+ Male–Male 10 Gbit/s

Passive DAC cable CBO CBL-0349L-BL 5 m SFP+ Male–Male 10 Gbit/s is a twinax direct attach cable designed for short-range, high-speed connections between SFP+ ports. The 5-metre passive assembly features SFP+ male connectors on both ends and supports 10 Gbit/s links without the need for separate optical transceivers. It is intended for use in top-of-rack, middle-of-row or adjacent-rack connections where low latency and simple, cost-effective cabling are required.

Advantages

This passive SFP+ twinax cable delivers a fixed 10 Gbit/s link with minimal latency and low power consumption because it does not require active components or additional transceivers. The integrated male-to-male SFP+ connectors simplify deployment with plug-and-play operation and reduce overall system cost compared with separate optical modules and fiber patch cords. Its 5 m length provides flexibility for intra-rack and short inter-rack runs while maintaining signal integrity typical for direct attach twinax designs.

Key specifications

How to use

Install the passive DAC by plugging each SFP+ male connector into the corresponding SFP+ port on your network devices until the connector latches. Verify link status in the devices' management interface or indicator LEDs to confirm the 10 Gbit/s connection. There is no separate configuration required at the physical layer; however, ensure compatible port settings (speed, duplex and any vendor-specific SFP+ compatibility requirements) are configured in the host equipment.

Recommendations

Avoid repeated flexing or tight bends near the connector ends and route the 5 m cable to prevent strain on the connectors. For optimal performance, use this passive twinax DAC for short links within racks or between adjacent racks and verify compatibility with device vendors when mixing equipment from different manufacturers.
