Unstressed receiver sensitivity testing is performed by simply connecting the transmitter to the receiver via a variable optical attenuator. BER values are recorded against different receiver power values and are finally plotted against each other. In optical communication systems, sensitivity is a measure of how weak an input signal can get before the bit-error ratio (BER) exceeds some specified number. The standards body governing the application sets this specified BER.

[pdf] By setting the water temperature generally between 13-17°C, mold temperature can be controlled more precisely, suitable for scenarios where high precision and production efficiency are needed. What It Is: The barrel (or screw) temperature refers to the heat applied to the plastic material inside the injection machine's barrel. It affects everything: surface finish, dimensional accuracy, cycle time, warpage, crystallinity, and even the internal stress locked inside the part. This involves several key temperature controls: barrel temperature, nozzle temperature, and mold temperature.

[pdf] Light emitter and a receiver form the sensing elements of an Optical time-of-flight (ToF) long range proximity and distance sensing system. The emitter sends modulated light pulses. These are commonly known by various names, including LIDAR and time of flight sensors, although there is actually overlap in. Optical distance sensors perform different measurement tasks in various applications with varying requirements with regard to accuracy, resolution and size. This document describes the detailed functionality of ToF proximity systems, explains the trade-offs involved in a typical ToF system and provides a step-by-step design flow.
