The DIGISOL DG-SA5250-CBL is a high-speed QSFP+ Direct Attach Cable (DAC) designed for short-range, high-bandwidth connectivity in enterprise and data center networking environments.
What It Is
A QSFP+ DAC cable integrates:
- high-speed twinax copper cable,
- QSFP+ connectors on both ends,
allowing direct device-to-device connections without separate optical transceivers or fiber patch cables.
These cables are commonly used for:
- switch uplinks,
- server aggregation,
- storage networking,
- spine-leaf architectures in data centers.
Key Features
- QSFP+ Interface
- Supports high-speed 40 Gigabit Ethernet connectivity.
- MSA Compliant
- Compatible with industry-standard QSFP+ ports.
- Hot Pluggable
- Can be connected or removed while equipment remains powered on.
- Low Power Dissipation
- Consumes less power compared to optical transceivers.
- 3.3V Single Power Supply
- Standard QSFP+ operating voltage.
- IEEE 802.3 Standard Support
- Ensures Ethernet interoperability and stable performance.
Typical Applications
- 40G switch uplinks
- Data center interconnects
- Server-to-switch connectivity
- High-performance computing clusters
- Storage Area Networks (SAN)
Advantages of QSFP+ DAC
Cost Efficient
- Much cheaper than using:
- QSFP+ optical modules
- fiber patch cords
Low Latency
- Excellent for high-speed internal networking.
Easy Deployment
- Plug-and-play installation.
Lower Power Usage
- Reduced thermal output compared to optical optics.
Limitations
- Suitable only for short distances
- usually 1m to 7m depending on cable type.
- Less flexible compared to fiber optic solutions.
