## Summary description

The BlueLAN QSFP DAC SC253501K3M30 is a 3m long cable featuring a QSFP connector on one end and 4xSFP+ connectors on the other. It is designed for high-speed data transfer in networking applications, ensuring reliable connectivity and performance.

## Long description

The BlueLAN QSFP DAC SC253501K3M30 3m 4xSFP+ Black is a 3-metre direct attach copper (DAC) cable that combines a QSFP plug on one end with four SFP+ plugs on the other. It is intended for short-reach, high-speed interconnections in data centres and networking racks, providing a fixed, low-latency link for equipment that supports QSFP to SFP+ breakout connections. The compact black cable supports reliable signal integrity and easy installation in dense cabling environments.
Advantages
This DAC cable offers a low-power, low-latency solution for connecting QSFP ports to multiple SFP+ ports without the need for transceivers. Its short 3 m length minimises signal attenuation for short-reach links while maintaining stable performance. The integrated breakout design simplifies cable management in racks and reduces the number of required optical modules, contributing to predictable performance and lower operational complexity.
Suitable for
Breaking out a QSFP port to up to four SFP+ ports in switch-to-switch or switch-to-server links
Short-reach connections within racks or between adjacent network equipment
High-density data centre deployments requiring compact cabling
Environments prioritising low latency and low power consumption
Key specifications
Cable type: Direct attach copper (DAC) breakout cable
Length: 3 m
Connectors: QSFP on one end, four SFP+ on the other end
Application: Short-reach high-speed interconnects (QSFP to SFP+ breakout)
Colour: Black
Weight: 0.25 kg
How to use
Identify the QSFP port on the host device and insert the QSFP connector carefully until it seats and the latch engages. Route the cable to the destination device and insert each SFP+ connector into the corresponding SFP+ port, ensuring proper orientation and latch engagement. Avoid sharp bends and maintain manufacturer-recommended minimum bend radius to preserve cable integrity. Verify link status on both devices and configure port settings as required by your network equipment to enable the breakout topology.
Usage recommendations
Use this 3 m QSFP to 4xSFP+ DAC for connections inside the same rack or between adjacent racks where short, low-latency links are required. Ensure the connected devices support DAC breakout configurations and check compatibility notes in equipment documentation before deployment.
