Optical modules are encapsulated in different modes to provide different structures. Huawei S series devices support optical modules of the following encapsulation types: CFP, QSFP+, QSFP28, XFP, SFP, eSFP, and SFP+. All optical modules are hot swappable. SFP: small form-factor pluggable. SFP ...

Application of these optical sensors ranges from computers to motion detectors. For optical sensors to work effectively, they must be the correct type for the application, so that they maintain their sensitivity to the property they measure. Optical sensors are integral parts of many common devices,...
liquid-crystal display: a display of information, as on digital watches, calculators, and many portable computers, using a liquid-crystal film that changes its optical properties when a voltage is applied. [1970–75] L.C.D. or l.c.d., least common denominator; lowest common denominator. ...
Sensors are devices that provide detection and measurement of a physical stimulus and converts that measurement into an electrical output signal that can represent the level, intensity, or strength of the property. Electrical signal outputs from a sensor can be in the form of a voltage, current,...

Position sensors are devices that can detect the movement of an object or determine its relative position measured from an established reference point. These types of sensors can also be used to detect the presence of an object or its absence. Position sensors are sometimes confused with proximity...
During the 20th century, cheap, lightweight, reliably made plastics became widely available and most low-cost optical devices now use plastic lenses (sometimes known as "organic glass"—made from materials such as polycarbonate) in place of glass ones (sometimes known as "mineral glass" to diffe...
