  Key considerations in choosing an optical power meter  Optical power meters for testing fiber optic components use semiconductor photodiodes as detectors to generate electrical current proportional to the incident optical power. This photocurrent is then measured, typically with a transimpedance amplifier and analog-to-digital converter, to… (Show more)

In a previous blog, we talked about a basic Type-C implementation without USB-PD. Today, we will discuss all the wonderful capabilities USB-PD brings to the Type-C connector plus a very important topic: SAFETY.   A non-PD Type-C implementation allows plug flipping and cable swapping. It also allows significant capability over BC 1.2, with non-PD… (Show more)

For proper USB testing, the first step is to get a copy of the USB 3.1 spec, CTS (Compliance Test Specification), and ECNs (Engineering Change Notice) from the USB-IF and ensure that your product meets the spec requirements. The link budgets for USB 3.1 are shown in Figure 1. To understand this diagram, let’s use the last row as an example. A… (Show more)
