March 9, 2009 -- Fiber-optic training company The Light Brigade announced that its new menu-based DVDs, "Fiber Optic Passive Devices" and "Fiber Optic Active Devices," are in production. The DVDs will be showcased at this month's OFC/NFOEC 2009.
According to the company, the "Fiber Optic Active Devices" DVD provides a basic understanding of optical components from theory to operation. It serves as a primer for anyone involved with lasers, LEDs, detectors and optical amplifiers, whether they are used at the component or sub-assembly level, or in fiber optic transmission systems.
Active devices are electronic components made up of semiconductor materials that actively manipulate electrons to perform the intended function. They require a source of energy to operate and have an output that is a function of present and past input signals. Types of active devices include controlled power supplies, transistors, light sources, amplifiers, and transmitters.
Also covered are:
-- The theory and fundamentals of electro-optical components.
-- Optical sources, such as LEDs, VCSELs, laser diodes, and optical amplifiers.
-- PIN, PIN-FET and APD detectors and their application in opto-electronic systems.
-- Transmitters and receivers, and how active components are manufactured, integrated, and tested.
-- Design and packaging for active optical components, and the roles of sources, detectors, transimpedance amplifiers, clock and data recovery, mux/demux, heat sinks and transponders.
-- Transceiver modules, such as TOSA, ROSA, MSA, XENPACK, X2, XPAK, SPF, and XFP.
-- How to employ test equipment with active devices to verify performance, quality and operation, and to characterize components.
The material is divided into menu-selectable chapters for easy access. The DVD's bonus materials include an acronym list, a glossary of related terms, and a quiz with student and instructor versions.
The "Fiber Optic Passive Devices" DVD serves as a primer on the various types of passive devices that have been developed for use in fiber optic communication systems. Fiber optic passive devices are purely optical instruments that work by guiding, refracting and reflecting light. Considered a cost-effective alternative to electro-optical components, these devices have become commonplace and are seeing wide use as components and optical sub-assemblies in communication systems.
The DVD's individual chapters detail the theory, manufacture and employment of various passive components and optical sub-assemblies, including an in-depth look at the technology and products used in wide, coarse and dense wavelength division multiplexing. Later chapters discuss the evolution of optical add/drop multiplexing as well as testing and test equipment for passive components.
The chapters include:
• Optical splitters and couplers.
• Wavelength division multiplexing devices.
• Optical isolators.
• Wavelength lockers.
• Dispersion compensators.
• Optical switches.
• Remote optical add/drop multiplexers.
Special features include a student quiz, with matching instructor version, written in Microsoft Word format to allow for customization for specific needs. In addition, the DVD features a comprehensive list of acronyms and a glossary of terms.
