Research of Attenuation Spectrum in Organic Optical Fiber
نویسندگان
چکیده
The main characteristic affecting on fiber transmission are attenuation and dispersion in optical fiber. The equipment of measuring attenuation has been set up in this letter. The attenuation in some organic optical fiber is measured. The lowest losses are 238dB/km at 670nm for PS core, 197 dB/km at 580nm for PMMA core, and 0.2dB/m at 650nm for C6H6 liquid-core optical fiber. Temperature and ultraviolet radiation affecting on loss in fiber are researched.

Impact of Fourth-Order Dispersion Coefficient on the Gain Spectrum and the Saturation Behavior of One-Pump Fiber Optical Parametric Amplifiers
In this paper, the gain spectrum and the saturation behavior of one-pump fiber optical parametric amplifiers (1-P FOPAs) are investigated by taking into account the fourth-order dispersion coefficient b4 in the analysis. The results show that it is necessary to consider b4 in the analysis when the wavelength difference between the signal and pump waves is large enough and/or whenever the pump w...
متن کاملImpact of Input Pump Profile on the Gain Spectrum and the Saturation Behavior of One-Pump Fiber Optical Parametric Amplifiers
In this article, the impact of input pump profile on the gain spectrum as well as the saturation behavior of one-pump fiber optical parametric amplifiers (FOPAs) is investigated. Since in practical circumstances, pump sources used for FOPAs have Lorentz-Gaussian profile instead of Gaussian, a more realistic case is considered for simulating FOPAs in this article. The results of simulations for ...
متن کاملA Full-Duplex, Dual-Polarization 10Gbps Radio over Fiber system with wavelength reuse for upstream signal
This study presents a full-duplex Radio-over-Fiber (RoF) system providing the users' wireless access with a bit rate of 10 Gbps over 40 GHz radio carrier. This system can be used in a centralized radio access network (C-RAN) architecture because we provide a fully analog front haul link between central station and base station. We can consider it as infrastructure between remote radio heads (RR...
متن کاملWavelength-dependent measurements of optical-fiber transit time, material dispersion, and attenuation.
A new, to our knowledge, method for measuring the wavelength dependence of the transit time, material dispersion, and attenuation of an optical fiber is described. We inject light from a 4-ns rise-time pulsed broadband flash lamp into fibers of various lengths and record the transmitted signals with a time-resolved spectrograph. Segments of data spanning a range of approximately 3000 A are reco...
متن کاملGraded-Index Polymer Optical Fiber (GI-POF)
Plastic Optical Fiber Perfluorinated graded-index polymer optical fibers (GI-POFs) combine high data transmission rates and low attenuation in the commercially desirable 850–1300nm range. GI-POFs offer a direct replacement and a low cost alternative to traditional glass. With ease of use and affordability, GI-POFs make an excellent choice for the installation of high performance fiber networks....
