Optical line termination. An Alcatel-Lucent OLT used by the French operator CityPlay. OLT and ONU in fiber optic network. An optical line termination (OLT), also called an optical line terminal, is a device which serves as the service provider endpoint of a passive optical network. It provides two main functions:
Optical power meter. An optical power meter (OPM) is a device used to measure the power in an optical signal. The term usually refers to a device for testing average power in fiber optic systems. Other general purpose light power measuring devices are usually called radiometers, photometers, laser power meters (can be photodiode sensors or ...
An optical time-domain reflectometer (OTDR) is an optoelectronic instrument used to characterize an optical fiber. It is the optical equivalent of an electronic time domain reflectometer which measures the impedance of the cable or transmission line under test. An OTDR injects a series of optical pulses into the fiber under test and extracts ...
Website. kingfisherfiber .com. Kingfisher International Pty Ltd [1] is an Australian manufacturer of fiber optic test and measurement equipment, located in Mulgrave, Victoria. [2] The company has worldwide distribution channels, and currently participates in various national and international standards development groups.
The test is usually administered in a waiting room and takes only a few minutes. The test has a total of 40 questions and consists of 4 different 10 page booklets. [3] On each page, there is a different scratch and sniff strip which are embedded with a microencapsulated odorant. There is also a four choice multiple choice question on each page.
Field testing is usually simpler. A special hand-held optical microscope is used to check for dirt or blemishes. A power meter and light source or an optical loss test set (OLTS) is used to test end-to-end loss, and an optical time-domain reflectometer may be used to identify significant point losses or return losses.
A fiber optic cable assembly with SC APC connectors, as commonly used to link optical network terminals to passive optical networks. A passive optical network (PON) is a fiber-optic telecommunications network that uses only unpowered devices to carry signals, as opposed to electronic equipment. In practice, PONs are typically used for the last ...
High-temperature operating life (HTOL) is a reliability test applied to integrated circuits (ICs) to determine their intrinsic reliability. This test stresses the IC at an elevated temperature, high voltage and dynamic operation for a predefined period of time. The IC is usually monitored under stress and tested at intermediate intervals.
