CBO DAC cable QSFP to QSFP 2.5 m BlueLAN (CAB-Q-Q-2.5M-BL)

The CBO DAC cable QSFP to QSFP 2.5 m BlueLAN is a fixed direct-attach copper link designed for short-reach high-speed interconnects. Intended for use with equipment that accepts QSFP-form-factor interfaces, this 2.5 meter cable provides a passive, low-latency physical connection between switches, routers or QSFP transceivers. The cable delivers energy-efficient electrical connectivity suitable for top-of-rack and server-to-switch links in data center and enterprise network environments where optical modules are not required.

Advantages

The direct-attach copper construction offers low latency and predictable electrical performance while avoiding the power and heat associated with active optical modules. A 2.5 m fixed length reduces clutter and simplifies rack cabling in short-reach installations. The QSFPto-QSFP form factor ensures compatibility with devices that support QSFP interfaces, enabling high-density port aggregation and simplified cross-connects without the need for separate transceivers or fiber patching.

Suitable for

• Top-of-rack switch to switch connections in data centers
• Server to switch interconnects for high-throughput servers
• Short-reach uplinks and cross-connects inside equipment racks
• Environments preferring passive copper links to reduce power consumption

Key specifications

• Connector type: QSFP to QSFP fixed copper assembly
• Cable length: 2.5 meters
• Transmission medium: Direct attach copper (passive copper cable)
• Typical use: Short-reach, high-speed electrical interconnects
• Color: Blue

How to use

Install by firmly seating each QSFP connector into the corresponding QSFP port on network devices until the connector latch engages. Ensure devices are powered down or that hot-plug behavior is supported according to the switch or server manufacturer’s guidance before insertion or removal. Route the cable inside the rack to avoid sharp bends and to maintain adequate airflow around equipment. Verify link status via device LEDs or management interfaces after connection.

Usage recommendations

Use this cable for short, high-speed interconnects where passive copper is supported. Avoid tensile stress and tight bending radii; maintain strain relief at connector ends. Confirm QSFP port compatibility and supported link speeds on both devices before deployment to ensure proper operation.
