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] A beam splitter or beamsplitter is an that splits a beam of into a transmitted and a reflected beam. It is a crucial part of many optical experimental and measurement systems, such as, also finding widespread application in.
[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.
[pdf] There have been multiple variants of the electrical interface of optical modules that have been used over the years. The earliest forms of optical modules had an analog electrical interface. In the transmit direction, the optical module would directly drive the laser or LED with the analog signal coming from the front system card. In the receive direction, the module would directly drive the receive electrical interface with the o.
[pdf] The CANverter is a compact, cost-effective I/O module for any high-speed physical layer CAN Network. It's light-weight and compact size makes it portable and simple to install. The DLCAN/DLCAN-R series represents a line of CAN to Fiber Optic Converters, designed to connect CAN field bus networks (e., CAN, CANopen, DeviceNet) via fiber optics. The converters come with 2 kV optical isolation for the CAN bus system and dual power inputs with alarm contact relay to ensure that your CAN bus system will remain online. is an industrial grade CAN bus to fiber converter that integrates 1 (or 2) standard fiber optic interfaces (single-mode, multi-mode, SC, ST optional) and 2 (or 1) standard CAN bus interfaces. The module operates at 12 or 24 VDC nominal (8 to 36 VDC) and provides 2-way, 300 Vrms isolation for FO and CAN.
