What Is the CAB-SFP-50CM= Cable Designed For?
The CAB-SFP-50CM= is a 50cm SFP+ passive direct-attach copper (DAC) cable optimized for short-reach, high-density Cisco network environments. It connects SFP/SFP+ ports on Cisco switches, routers, or servers, supporting 10Gbps data rates with minimal latency. Its compact length makes it ideal for linking adjacent devices in racks or top-of-rack (ToR) deployments.
Core Technical Specifications
- Connector Type: SFP+ to SFP+ (28 AWG twinaxial copper).
- Max Data Rate: 10 Gbps (supports 1G/10G auto-negotiation).
- Compatibility: Cisco Nexus 9000, 3000 series, UCS servers, and other SFP+-enabled devices.
- Temperature Range: 0°C to 70°C (32°F to 158°F), suitable for data center environments.
CAB-SFP-50CM= vs. Longer SFP Cables: Key Differences
| Feature | CAB-SFP-50CM= | 1M/3M SFP Cables |
|---|---|---|
| Length | 50cm (0.5m) | 1m, 3m, or longer |
| Use Case | Same-rack device stacking | Cross-rack/cabinet links |
| Latency | Near-zero signal delay | Marginally higher latency |
| Airflow Impact | Minimal cable clutter | Increased obstruction risk |
Why Choose the 50cm Length for High-Density Deployments?
- Space Efficiency: Reduces cable slack in tightly packed racks, improving airflow and cooling efficiency.
- Cost-Effectiveness: Passive DAC design eliminates the need for separate transceivers, lowering power consumption and costs.
- Reliability: Cisco-certified construction ensures error-free performance at 10Gbps, critical for latency-sensitive applications like financial trading or real-time analytics.

Practical Insight
Having managed large-scale data centers, I’ve seen 50cm cables like the CAB-SFP-50CM= transform rack organization. Longer cables often create spaghetti-like chaos, obstructing airflow and complicating maintenance. In contrast, the precision length of this cable streamlines cable management, reduces thermal hotspots, and simplifies upgrades—factors that directly impact uptime and operational costs. While longer cables have their place, neglecting the right short-reach option in dense setups is a preventable oversight.
