Acousto-optic modulators are devices that use sound waves to modify the amplitude, frequency, or phase of light passing through an acousto-optic material

Optical modulators vary the amplitude and phase of a light beam; e.g., from a laser or by sound waves

Fiber optic attenuators are devices that reduce signal power in fiber optic links by inducing a fixed or variable loss. They are used to control the power level of optical signals at the outputs of light sources and electrical-to-optical (E/O) converters. They are also used to test the linearity and dynamic range of photo sensors and photo detectors.

Quadrature phase shift keying (QPSK) modulators and binary phase shift keying (BPSK) modulators are used to change certain characteristics (amplitude, frequency or phase) of a carrier signal in order to transmit information. The changes in the parameter(s) of the carrier are made in accordance with an information-bearing signal (modulation signal

I/Q modulators and I/Q demodulators change the amplitude, frequency, or phase of a carrier signal in order to transmit information. I/Q modulators split an incoming data stream into its in-phase (I) and quadrature (Q) components, mix the resulting signals with local oscillators that are 90º apart in phase, and then combine the outputs vectorially in a 0º mixer

Electro-optic modulators are analog or digital devices that use an electric field to alter the characteristics (e.g., band gap and index of refraction) of a material through which light is traveling, changing the characteristics of the light itself

Metal shapes and stock includes metals and alloys in the form of bar, rod, beam, plate, foil and other standard shapes.

RF transmitters are electronic devices consisting of an oscillator, modulator, and other circuits that produce an RF signal

Profiles and structural shapes include shaped stock with uniform cross sections such tees, angles or beams manufactured through extrusion, continuous casting, roll forming, and other processes.

Optical scanners are motorized mirror mounts and system used in scanning applications.

Fiber optic filters allow only specific wavelengths to pass into a larger fiber optic system.

RF transceivers are electronic devices that receive and demodulate an RF signal, then modulate and transmit a new signal

Access points are transmitter / receivers (transceivers) that connect to a network through an interface such as a bus or connector. They receive, store, and transmit data between the wireless LAN and the wired structure.

Digital audio systems electronically record and store audio signals such as voice, music, alarm, and security messaging for broadcast, editing, monitoring, and playback.

Carbon steels and alloy steels are ferrous alloys that contain carbon and other alloying elements such as manganese, chromium, molybdenum, and nickel.
