Design optimization of NZDSF for low latency in iot optical fiber network

شما اینجا هستید

Due to ever–increasing demands for optical fibers with low–latency used in IoT optical fiber networks, in this theoretical study, a non–zero dispersion shifted fiber (NZDSF) with a particular refractive index which had a minimum latency at 1352 nm is designed.‎ In comparison to a commercial NZDSF, the latency has improved by 0.‎002ìs in the designed NZDSF with an effective area of 102 and macro bending loss of 517.‎3 /110−×dBkm.‎ The dispersion of this fiber is found to be 1.‎10625ps/nm.km which is comparable to the commercial NZDSF fiber.‎
We have designed an optical fiber network used in IoT in order to evaluate the quality of the received signals from 50 km of our designed NZDSF fiber.‎ The results have shown that without using optical amplifier and DCF, the quality factor and minimum bit–error rate are obtained as 8.‎17 and 1610−, respectively.‎
