## Summary description

Direct attach copper (DAC) cable BlueOptics SFP-DAC100-3M-BL with QSFP28 connectors at both ends. 3 m length, designed for 100GBASE-CR4 links and high-speed InfiniBand or fibre-optic-compatible interconnects. Used to connect switches, routers and network adapters where short-reach 100 Gbps connectivity is required; plug-and-play with compatible QSFP28 ports.

## Long description

BlueOptics SFP-DAC100-3M-BL is a 3 m passive Direct Attach Cable (DAC) with QSFP28 connectors on both ends, designed for short-distance 100GBase-CR4 electrical links in data centers and rack-to-rack connections. The cable is a twinax copper solution intended for use where hardware platforms support passive QSFP28 twinax DACs.
Advantages
This passive QSFP28 DAC offers a simple, low-power connection for short-range 100 Gbit/s links. Its twinax copper design provides low latency and a compact, easy-to-install form factor. The cable is black, weighs approximately 0.15 kg and is compatible with equipment that accepts QSFP28 passive DACs.
Suitable for
Short-distance connections between switches in a rack
Inter-rack links in adjacent racks
High-density switch-to-switch or switch-to-storage connections
When it may not be suitable
This passive DAC is intended for short-reach electrical links; it is not suitable for long-distance transmission or fiber-optic runs. It requires networking hardware that explicitly supports passive QSFP28 twinax DACs—using it in unsupported ports may result in incompatibility or loss of link functionality.
Key specifications
Type: Passive Direct Attach Cable (DAC), twinax copper
Connectors: QSFP28 male to QSFP28 male
Data rate: up to 100 Gbit/s (100GBase-CR4)
Length: 3 m
Colour: Black
Typical power draw: ~0.1 W (passive cable; actual consumption depends on connected devices)
Approximate weight: 0.15 kg
How to use
Insert each QSFP28 connector into the QSFP28 port of the devices to be connected, ensuring the connectors are fully seated and any retention latches are engaged. Verify that both devices support passive QSFP28 DACs and the 100GBase-CR4 electrical interface. After physical installation, confirm link status and configure port settings on the switches or routers as required by your network design.
What to consider before purchase
Confirm that your switches, routers or storage devices support passive QSFP28 twinax DACs and 100GBase-CR4.
Ensure 3 m length is appropriate for your rack or inter-rack cabling plan.
Check that electrical short-reach copper cabling is acceptable for your environment (versus optical solutions).
Usage recommendations
Use this BlueOptics QSFP28 DAC for short, high-bandwidth links in data center racks where low latency and low power consumption are priorities; avoid excessive bending of the twinax cable and keep within the recommended bend radius to maintain signal integrity.
