The following table outlines distance suitability:

Because of this limitation, network designs often combine DAC and optical solutions to achieve both short- and long-range connectivity.

Cable Flexibility and Routing

PAN SFP-PLUS-CU-5M uses twinax copper cabling, which is thicker and less flexible than fiber optic cables. This can create challenges in high-density environments where cable routing and airflow management are critical.

Key considerations include:

• Larger bend radius compared to fiber cables
• Increased cable bulk in high-port-density racks
• Potential obstruction of airflow if not properly managed

Typical routing challenges and mitigation strategies:
