Laser diodes, the devices that illuminate telecom fiber-optic cables, require light-current-voltage (L-I-V) measurements during production. These measurements let you characterize a laser diode's ...

The resistance of the diode cannot be measured with the normal ohmmeter on a DMM because the voltage used may not be high enough to bias the diode. DMM’s often have a diode testing mode that supplies ...

The Model 2520 Pulsed Laser Diode Test System performs electrical characterization of laser diodes in either the chip/bar state or in finished products. According to its manufacturer, the 2520 is the ...

The Keithley System 25, a fully customizable test system for the light-current-voltage (LIV) characterization of laser diodes and assembled laser-diode modules (LDMs), lets users choose only the ...

Since wireless radio transmissions were first achieved in the 1880s, telecommunications have evolved to the point where instant global communication is a daily reality, currently contributing more ...

Humans are walking high voltage generators, due to all the friction with our surroundings, wide variety of synthetic clothes, and the overall ever-present static charges. Our electronics are sensitive ...

With the ongoing increase in module operating current, a reliable junction box is critical for modules which are to last for 25 to 30 years. This article will analyse which factors need to be ...
