## Summary description

BlueOptics CAB-Q-S-2M-CT-BL Direct Attach Copper breakout cable with a length of 2 meters. Features a QSFP connector on one end and 4x SFP+ connectors on the other. Designed in black for high-speed network connections, data centers, and enterprise networking environments.

## Long description

The BlueOptics CAB-Q-S-2M-CT-BL is a passive Direct Attach Copper breakout cable designed for high-speed network connections in data centers and enterprise networking environments. Featuring a length of 2 meters, this reliable cable connects a 40G QSFP interface on one end to four independent 10G SFP+ interfaces on the other, enabling seamless device linking and efficient data transmission.
Advantages
This breakout cable offers a cost-effective and energy-efficient solution for interconnecting networking hardware without the need for additional optical transceivers. Its durable construction ensures stable signal integrity across short distances, while the black color provides a clean and professional appearance in server racks and structured cabling setups.
Suitable for
Data center server and switch interconnections
Enterprise networking and high-performance computing
Connecting 40G QSFP ports to 10G SFP+ equipment
When it may not be suitable
This cable is not designed for long-distance network connections, as passive DAC cables are strictly limited to short-range intra-rack or adjacent-rack links. It is also unsuitable for environments requiring non-copper physical media or connections between incompatible port types without appropriate protocol support.
Key specifications
Cable type: DAC
Cable length: 2 m
Connector 1: QSFP
Connector 2: 4x SFP+
Product colour: Black
Weight: 0.25 kg
How to use
Ensure that both networking devices are powered off or configured to handle hot-swapping before installation. Insert the QSFP connector firmly into the 40G port of the primary switch or router until it clicks into place. Then, connect each of the four SFP+ ends into the respective 10G ports of the target devices, ensuring secure retention mechanisms are engaged.
What to consider before purchase
Verify that your networking hardware supports passive Direct Attach Copper breakout cables
Measure the required distance to ensure the 2-meter length is sufficient between connected devices
Confirm port compatibility, specifically the presence of one QSFP port and four available SFP+ ports
Usage recommendations: Handle the cable with care by gripping the connector housings rather than pulling on the wire itself during insertion and removal. Avoid sharp bends and route the cable neatly through rack management channels to maintain optimal lifespan and signal performance.
