| contents | Optical partitioning for multicarrier generation in subcarrier multiplexed networks Fabián Ranulfo Cuesta Quintero Gustavo Adolfo Puerto Leguizamón Carlos Arturo Suárez Fajardo Ingeniería Radio over Fiber Spectral partitioning subcarrier multiplexing Optical access networks Broadband optical sources Objective– To evaluate the multicarrier generation technique based on spectral segmentation for the transport of optical subcarrier multiplexing signals. Methodology– The proposal is evaluated through experimental validation and modeling based on simulation of the generation of optical carriers using a broadband source in combination with an optical filter configured with different pass bands and transmission at different distances. Results– The experimental evaluation measured the Error Vector Magnitude (EVM) for 1nm, 3nm, 6nm and 8nm optical slices that transport QPSK and 16QAM modulation formats at 1 GHz and 3 GHz subcarriers over a fiber link of 10 km. For the case of 1nm pass band and QPSK modulation, an EVM of 29.6458% was found while an EVM of 40.4685% for the service transported in 16QAM was measured. The simulation model showed that a bit error rate of 1x10-12 is achieved for spectral partition sizes of 100MHz on 5GH, 30GHz and 60GHz subcarriers. Conclusions– The experimental results showed that the measured EVM did not show significant difference regarding the subcarrier frequency for a QPSK service. However, the 16QAM modulation is recommended only when the subcarrier frequency is 1GHz or below for a correct equalization of the received signal. Simulation modeling evaluated the approach at higher subcarrier frequencies and longer distances, results found show that a 60GHz subcarrier over a fiber link of 40km is feasible for a slice size of 100MHz. 2020 artículo científico 0122-6517 https://www.redalyc.org/articulo.oa?id=497779336017 en http://www.redalyc.org/revista.oa?id=4977 INGE CUC application/pdf Corporación Universitaria de la Costa INGE CUC (Colombia) Num.1 Vol.16 |
