See Bel (B).
- BB-I
- Abbreviation for broadband interactive services. The delivery of all types of interactive video, data, and voice services over a broadband communications network.
- Backreflection
- In cases where light is launched into an optical fiber, backreflection refers to the light that is returned to the launch point.
- Backscattering
- The return of a portion of scattered light to the input end of a fiber; the scattering of light in the direction opposite to its original propagation.
- Bandgap Energy
- Energy gap in semiconductors and insulators. The forbidden energy level separating the valence band and the conduction band in a semiconductor or insulator. Expressed in electron Volts (eV).
- Bandwidth
- The range of frequencies within which a fiber optic waveguide or terminal device can transmit data or information.
- Bandwidth-limited Operation
- The condition in a fiber optic link when bandwidth, rather than received optical power, limits performance. This condition is reached when the signal becomes distorted, principally by dispersion, beyond specified limits.
- Baseband
- A method of communication in which a signal is transmitted at its original frequency without being impressed on a carrier.
- Baud
- A unit of signaling speed equal to the number of signal symbols per second, which may or may not be equal to the data rate in bits per second.
- Beamsplitter
- An optical device, such as a partially reflecting mirror, that splits a beam of light into two or more beams. Used in fiber optics for directional couplers.
- Bel (B)
- The logarithm to the base 10 of a...
