PoE Load Testing: Advanced Troubleshooting for Your PoE Systems

Since the original IEEE 802.3af Type 1 power over Ethernet (PoE) standard that delivered up to 15.4 Watts (W) was first introduced in 2003, the technology has evolved to include Type 2 (up to 30 W), Type 3 (up to 60 W), and Type 4 (up to 90 W). That means PoE voltage now supports everything from phones, Wi-Fi access points, and surveillance cameras, to laptops, digital displays, and even facility-wide LED lighting—all requiring various levels of PoE power.

Fiber Polarity Basics

Polarity defines direction of flow, such as the direction of a magnetic field or an electrical current.

A fiber optic link’s transmit signal (Tx) at end of the cable must match the corresponding receiver (Rx) at the other end. So, what is fiber polarity? Fiber polarity could be defined as the direction light signals travel from one end to the other end of an optical fiber cable.
