DAC cable CBO QSFP Direct Attach 30 m, model CBL10600230

Passive direct-attach copper (DAC) cable BlueOptics CBL10600230 with QSFP connectors and 30 m length is a fixed copper interconnect for short-range, high-speed links. It is intended to connect compatible QSFP ports in switches, routers and servers for rack-to-rack or in-rack cabling. The cable provides a low-latency, power-efficient alternative to optical transceivers for applications where copper reach is sufficient and offers straightforward plug-and-play installation without additional modules.

Advantages

The DAC cable delivers predictable electrical performance and low latency for high-throughput network paths. Being a passive copper solution, it eliminates the need for separate optical transceivers and reduces overall port cost and power consumption. With QSFP end connectors and a 30 m length, the cable supports aggregated 40/100 Gbps class interfaces where vendor compatibility is met and simplifies short-distance interconnects inside data center racks or between adjacent racks.

Suitable for

• Rack-to-rack connections in data centers
• Interconnects between switches and aggregation devices
• Links between servers and top-of-rack switches
• Short-reach high-throughput network segments

Key specifications

• Connector type: QSFP on both ends
• Cable type: Passive copper direct-attach
• Length: 30 m
• Typical use: Short-range high-speed interconnects (data center / rack-level)
• Latency: Low, typical of copper DAC connections
• Power: Passive design requires no additional power for transceivers

How to use

Insert each QSFP connector into the corresponding QSFP port on compatible networking equipment, ensuring proper alignment of the connector key. Verify that both devices support passive copper DAC cables and the required data rates before powering the links. After connection, confirm link status through device management interfaces and monitor for correct speed and lane negotiation. For installation, route the cable to avoid sharp bends and mechanical strain on connectors; secure with appropriate cable management to maintain signal integrity.

Recommendations

Use this passive DAC cable for short-distance links where the 30 m copper reach is sufficient and confirmed compatible with the equipment vendor. Avoid environments with high electromagnetic interference and do not exceed recommended bend radius. For longer distances or optical isolation requirements, consider optical transceivers and fiber cabling instead.
