What is the DC Loop Resistance which is often named Resistance Unbalance?
Why It's Important:
Current Imbalance: Resistance unbalance can cause a current imbalance in the cabling system, which might lead to inefficiencies and potential damage to equipment.
.
Power over Ethernet (PoE): For systems implementing PoE, resistance unbalance can affect the performance and reliability of power delivery to devices like IP phones, wireless access points, and network cameras.
.
Compliance with Standards: Standards like IEEE 802.3af, IEEE 802.3at, and IEEE 802.3bt specify limits for resistance unbalance to ensure proper functioning and safety.
