Most of these links use red laser diodes, even though the attenuation spectrum of poly(methyl methacrylate) (PMMA), the basic polymer used to manufacture these fibers, has a lower minimum in the green region. Therefore, we set out to explore the potential use of green light in transmission systems, comparing the performances of three step-index polymer optical fibers (SI-POFs) with different numerical apertures. We obtained measurements of intensity distribution, frequency response and bit error rate (BER), as functions of fiber length. We have also compared the fibers’ frequency responses with red and green light for a few selected lengths. Our results confirm that SI-POFs attenuate less in response to green light, which can increase their length. This advantage is partially counterbalanced by a slightly higher dispersion that limits the capacity of the high-aperture fibers, particularly at relatively short lengths. Our conclusions are critical to understanding SI-POF behavior and to designing thorough SI-POF models that can aid the design of POF-based links for different scenarios. info:eu-repo/grantAgreement/ES/DGA/T20-20R info:eu-repo/grantAgreement/ES/MICINN/RTI2018-094669-B-C33 info:eu-repo/grantAgreement/ES/UZ/OTRI-2019-0626 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 4.967 2021 POLYMER SCIENCE 16 / 90 = 0.178 2021 Q1 T1 0.726 2021 Polymers and Plastics 2021 Q1 Chemistry (miscellaneous) 2021 Q1 5.7 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Mazo Bañares, María López Lucia, Alicia Universidad de Zaragoza (orcid)0000-0002-5622-9993 Muzás Bardají, Candela Universidad de Zaragoza (orcid)0000-0002-4443-0614 Mateo Gascón, Javier 5008 800 Universidad de Zaragoza Dpto.
