## Long description

The BlueOptics FN-CABLE-QSFP28-4SFP28-1 QSFP28 DAC 1m Black is a direct-attach copper cable designed for short-reach, high-bandwidth interconnections in data center and enterprise networks. With a 1 meter length and support for data rates up to 100 Gbps, this cable provides a low-latency, energy-efficient connection between QSFP28 ports and SFP28 ports using a QSFP28 to 4×SFP28 breakout configuration. The black jacket and robust construction are intended to withstand repeated handling in rack environments while maintaining signal integrity for demanding applications.
Advantages
This DAC cable offers native support for 100 Gbps links with low power consumption compared to optical transceivers, enabling cost-effective connectivity for short-distance links. Its passive copper design reduces heat and power requirements, while the compact 1 m length limits excess cable slack in dense rack deployments. The cable’s durable outer jacket and standardized connector interfaces ensure compatibility with compatible QSFP28 and SFP28 ports and reliable mechanical performance during installation and maintenance.
Suitable for
High-speed switch-to-switch connections in data centers
Server-to-top-of-rack switch links
Short-reach aggregation and spine-leaf fabrics
Environments where low latency and low power are required
Key specifications
Interface: QSFP28 to 4×SFP28 breakout
Length: 1 meter
Maximum data rate: up to 100 Gbps
Cable type: Direct Attach Copper (DAC), passive
Jacket color: black
Connection: compatible with QSFP28 and SFP28 ports
How to use
Ensure both devices are powered down or follow hot-plug guidelines from your hardware vendor before connecting. Align the QSFP28 connector with the QSFP28 port and insert until secure; align each SFP28 connector with the respective SFP28 ports and insert fully. Verify link status through your switch or server management interface and confirm negotiated speeds. When removing the cable, press any release latch on the connectors and pull straight out to avoid damaging the port. Store the cable without sharp bends and avoid kinking to preserve signal integrity.
Usage recommendations
Use this 1 m QSFP28 to 4×SFP28 DAC for short-reach interconnects inside racks or between adjacent racks. For runs longer than a few meters or when optical isolation is required, consider using appropriate active copper assemblies or fiber-optic transceivers and cabling.
