The Problem: The signal is too strong and is blinding or burning the receiver. Common Causes: Using a Long-Range module (like ZR 80km) for a Short-Range test (e., connecting two switches in the same rack). The Fix: NEVER plug an ER or ZR module directly into another without fiber. The strength of this light is measured in dBm (decibel-milliwatts). Why dBm and not Watts? In networking, we use a. I just started using URP today, and I noticed that the point lights now are extremely strong near the source of light but get dimmed too quickly so objects that are supposedly within range don't get much light. Without it, the lamp would overheat or draw too much current and burn out. Older fixtures typically used magnetic ballasts. Modern systems usually employ electronic. Solar panels are designed to operate under sunlight and are generally not at risk of burning out due to strong light.
