The DIGISOL DG-SA2240-CBL-1M is a high-speed SFP+ Direct Attach Cable (DAC) designed for short-distance 10 Gigabit network connections between networking devices such as switches, servers, and storage systems.
What It Is
A DAC cable combines:
- twinax copper cable
- integrated SFP+ connectors on both ends
into a single plug-and-play unit.
It is commonly used instead of fiber optics for short-distance 10G connectivity inside:
- server racks,
- data centers,
- enterprise networks.
Main Features
- SFP+ MSA Compliant
- Compatible with standard SFP+ interfaces.
- Hot Pluggable
- Can be connected/disconnected without powering down devices.
- Low Power Consumption
- More power-efficient than many optical modules.
- 3.3V Power Supply
- Standard operating specification.
- IEEE 802.3 Compliance
- Supports Ethernet networking standards for reliable interoperability.
- 1 Meter Cable Length
- Ideal for rack-to-rack or within-rack connections.
DAC vs Fiber Transceiver
Advantages of DAC
- Lower cost than optical transceivers
- Very low latency
- Simple deployment
- No separate fiber patch cords needed
- Lower power usage
Limitations
- Short-distance only
- Less flexible than fiber
- Thicker cable compared to optical fiber
Typical Use Cases
- Switch-to-switch 10G links
- Switch-to-server connections
- Storage networking
- Top-of-rack (ToR) deployments
- Data center interconnects
Compatible Devices
Works with many SFP+ capable devices from:
- DIGISOL
- Cisco
- MikroTik
- Ubiquiti
- Juniper
- HPE
Important Clarification
The description mentions QSFP+ in one place and SFP+ DAC in the product name. These are different standards:
| Type | Speed |
|---|---|
| SFP+ | 10Gbps |
| QSFP+ | 40Gbps |
Based on the model name DG-SA2240-CBL-1M, this appears to be an SFP+ DAC cable, not QSFP
