standard test signal
Telecommunications; General telecom
A single-frequency signal with standardized level used for testing the peak power transmission capability and for measuring the total harmonic distortion of circuits or parts of a ...
doubly clad fiber
Telecommunications; General telecom
A single-mode fiber that has two claddings. Note 1: Each cladding has a refractive index that is lower than that of the core. Of the two claddings, inner and outer, the inner ...
w-profile fiber
Telecommunications; General telecom
A single-mode fiber that has two claddings. Note 1: Each cladding has a refractive index that is lower than that of the core. Of the two claddings, inner and outer, the inner ...
dispersion-unshifted fiber
Telecommunications; General telecom
A single-mode optical fiber that has a nominal zero-dispersion wavelength in the 1. 3-m transmission window. Synonyms dispersion-unmodified fiber, EIA Class IVa fiber, nonshifted ...
quadruply clad fiber
Telecommunications; General telecom
A single-mode optical fiber that has four claddings. Note 1: Each cladding has a refractive index lower than that of the core. With respect to one another, their relative ...
dispersion-shifted fiber
Telecommunications; General telecom
A single-mode optical fiber that has its minimum-dispersion wavelength shifted, by the addition of dopants, toward its minimum-loss wavelength. Synonym EIA Class IVb fiber.
suppressed carrier single-sideband emission
Telecommunications; General telecom
A single-sideband emission in which the carrier is virtually suppressed and not intended to be used for demodulation.
