TABLE OF CONTENTS Fiber Optic Reference Guide: A Practical Guide to Communications Technology, Third Edition
G
- G
- Abbreviation for giga. One billion or 10 9.
- GaAlAs
- Abbreviation for gallium aluminum arsenide. A semiconductor material used to make short wavelength light emitters.
- GaAs
- Abbreviation for gallium arsenide. A semiconductor material used to make light emitters.
- Gain
- The ratio of output current, voltage, or power to input current, voltage, or power, respectively. Usually expressed in dB.
- GaInAsP
- Abbreviation for gallium indium arsenide phosphide. A semiconductor material used to make long wavelength light emitters.
- Gap Loss
- Loss resulting from the end separation of two axially aligned fibers.
- Gate
- 1. A device having one output channel and one or more input channels, such that the output channel state is completely determined by the input channel states, except during switching transients. 2. One of the many types of combinational logic elements having at least two inputs.
- Gaussian Beam
- A beam pattern used to approximate the distribution of energy in a fiber core. It can also be used to describe emission patterns from surface-emitting LED's. Most people would recognize it as the bell curve. The equation that defines a Gaussian beam is:
- GBaud
- One billion bits of data per second or 10 9 bits.
- Gb/s
-
See GBaud.
- Ge
- Abbreviation for germanium. An element used to make detectors. Good for most wavelengths (e.g., 800 1600 nm).
- Genlock
- A process of sync generator locking. This is usually performed by introducing a composite video signal from a master source to the subject sync generator. The generator to be locked has circuits...
