## Long description

The CBO QSFP Direct Attach Cable SC252501K3M30-BL — 40GBASE-CR4, 3 m, blue is a 3-meter copper direct-attach QSFP cable engineered for short-range 40GBASE-CR4 connections. Designed to link QSFP ports directly, this blue cable eliminates the need for separate optical transceivers and is intended for use in data center and rack-to-rack environments. It supports high-throughput, low-latency links between switches, routers or servers while simplifying cabling and reducing component count.
Advantages
This direct attach cable provides a cost-effective and compact solution for short-distance 40 Gb/s links. As a copper DAC, it offers lower power consumption compared with active optical solutions and reduces the number of field-replaceable transceivers. The fixed 3 m length and robust QSFP connectors ensure predictable signal integrity and easy installation in dense rack environments. The blue jacket helps with visual identification and cable management in multi-cable installations.
Suitable for
Short-range interconnects between switches within the same rack or adjacent racks
Server-to-switch high-speed links in data centers
Top-of-rack and middle-of-row connectivity where 40GBASE-CR4 is required
Environments seeking lower power and simplified cabling compared with transceiver-based links
Key specifications
Standard: 40GBASE-CR4 copper direct attach
Connector type: QSFP to QSFP
Length: 3 m
Cable medium: Twinax copper
Color: Blue
Use case: Short-reach, rack-to-rack or intra-rack links
How to use
Insert each QSFP connector into the corresponding QSFP port on the devices to be connected, ensuring the latch mechanism engages securely. Verify link status on both devices and confirm 40 Gb/s operation through the equipment management interface. Avoid sharp bends and maintain the manufacturer’s recommended bend radius to preserve cable performance. The cable is intended for direct QSFP-to-QSFP connections and does not require additional transceivers or patch panels for operation.
Usage recommendations
Install the cable in clean rack spaces and route it to minimize electromagnetic interference from power lines. Use the 3 m length for connections within the same rack or adjacent racks; for longer distances select an appropriate optical or active copper solution. Periodically inspect connectors for dust or damage and clean with approved tools before insertion.
