On an optical network, a sender needs to convert electrical signals into optical signals before sending them to a receiver, and the receiver needs to convert received optical signals into electrical signals. An optical module is a component that completes electrical/optical conversion on an optical ...
The side with an L-shaped notch close to the connector is the top of a QSFP+ optical module, as shown in Figure 9-6. When connecting a QSFP+ optical module to a port, keep the top side upward. Do not insert the QSFP+ optical module upside down. Currently, there is no formal stand...
An optical answer sheet is a form which is covered in a numbered and lettered grid of bubbles. These bubbles can be filled out by users to convey specific information, and the completed optical answer sheet can be fed through a machine which is capable of reading and interpreting the filled ...
An optical drive is a piece of equipment that uses a laser to read or write information on a disc. Though this type of equipment is often associated with computers, it can stand alone as an appliance. For instance, a Digital Versatile Disc (DVD) player, Blu-ray disc (BD) player, and...
What is an optoisolator (optical coupler or optocoupler)? An optoisolator (also known as an optical coupler, photocoupler, optocoupler) is asemiconductordevice that transfers an electrical signal between isolated circuits using light. These electronic components are used in a wide variety of communica...
What is an optical mouse? An optical mouse is an advanced computer pointing device that uses a light-emitting diode (LED), optical sensor and digital signal processor (DSP) in place of the traditional mouse ball and electromechanicaltransducer. Movement is detected by sensing changes in reflected...
A fiber optic sensor operates with an optical fiber cable connected to a dedicated light source. These sensors offer great mounting flexibility and can be used is in a variety of environments.
The quest for on-chip optical isolators has recently spawned many new isolator structures. However, there has been some confusion about the requirement of nonreciprocity. Here, we review the essential characteristics of an isolator.
