## Long description

The BlueOptics DAC Breakout Cable CAB-Q-S-1M-CT-BL QSFP to 4x SFP+ 2 m Black is a high-performance passive Direct Attach Copper cable designed for efficient high-speed data transmission. Measuring 2 meters in length and featuring a black color finish, this twinax copper cable provides a reliable physical bridge between networking equipment. It is engineered with a QSFP connector on one end and four individual SFP+ connectors on the other, allowing seamless fan-out connections for modern data centers and enterprise server environments.
Advantages
This Direct Attach Copper cable offers a cost-effective and energy-efficient alternative to optical transceivers for short-range network links. With a passive design that consumes minimal power and introduces virtually no latency, it helps maintain optimal thermal and electrical efficiency within server racks. The integration of high-grade components ensures high reliability, dependable signal integrity, and an extended operational lifespan suitable for mission-critical IT infrastructure.
Suitable for
Interconnecting 40G network switches with 10G servers
Linking adjacent server racks in data centers
High-speed enterprise storage system connections
Short-distance high-throughput network expansion
When it may not be suitable
This passive copper breakout cable is not designed for long-distance data transmission exceeding a few meters, as optical fiber solutions are required for extended reaches. Additionally, it cannot be used with networking hardware that does not natively support passive DAC twinax configurations on its ports.
Key specifications
Cable type: DAC (Direct Attach Copper)
Cable length: 2 m
Connector 1: QSFP
Connector 2: 4x SFP+
Color: Black
Data transfer rate: Up to 40 Gbit/s
How to use
To install the cable, ensure that both connected networking devices are powered off or follow standard hot-plug procedures if supported by your hardware platform. Insert the QSFP connector firmly into the 40G port of the primary switch or router until it clicks into place. Then, take the four SFP+ connectors on the opposite end and plug them securely into the corresponding 10G ports on target servers, switches, or storage units. Ensure proper cable routing to avoid sharp bends and excessive strain on the connectors.
What to consider before purchase
Verify that your network hardware supports passive DAC breakout cables
Check the required physical distance between connected devices to ensure 2 meters is sufficient
Confirm port compatibility for QSFP and SFP+ interfaces on your switches and servers
Usage recommendations: Always handle the connectors by their latching mechanisms rather than pulling on the cable itself to prevent internal damage. Keep network ports clean and free of dust before insertion to maintain stable and error-free signal transmission.
