DAC cable CBO 02311KNX 100G 3M — Direct Attach Copper 3 m, 100 Gigabit

Direct Attach Copper (DAC) cable CBO 02311KNX 100G 3M from BlueOptics is a 3‑meter passive twinax assembly engineered for 100 Gigabit links. It provides a short‑reach, electrical connection between switches, routers and servers with 100G ports. The cable is intended for data centre top‑of‑rack and aggregation deployments where low latency, predictable performance and cost efficiency are required.

Advantages

The DAC cable offers low latency and consistent electrical performance for short-distance 100G links without the need for additional transceivers. Its passive construction reduces power consumption and complexity compared with active optical solutions, while twinax copper delivers stable signal integrity for rack-to-rack or within-rack connections. The 3 m length balances reach and cable management in dense equipment rows.

Suitable for

• Top-of-rack connections between switches and servers
• Aggregation links in data centre fabrics
• Short-distance 100G interconnects inside equipment racks
• Low-latency, high-bandwidth applications requiring cost-effective cabling

Key specifications

• Form factor: direct attach twinax copper assembly
• Rated speed: 100 Gigabit Ethernet
• Length: 3 metres
• Construction: passive copper (twinax)
• Application: short-range data centre interconnects (within or between racks)
• Latency: electrical link with minimal additional delay compared to optical transceivers

How to use

Insert each connector into the corresponding 100G port on the network devices until the latch engages, ensuring a secure mechanical connection. Route the cable to avoid sharp bends and maintain recommended bend radius; secure with cable ties or management panels to prevent strain on the connectors. Verify link status on both devices and, if necessary, configure the ports to operate at 100G or the supported interface mode.

Recommendations

Use this 3 m passive DAC cable for short-range connections where 100G electrical interfaces are supported and where reduced power consumption and lower cost are priorities. Avoid running the cable near strong electromagnetic interference sources and replace if physical damage or connector wear is observed.
