“…Tan et al [7] performed a study in coherent optical sampling to monitor optical signal-to-noise ratio (OSNR) in high-speed optical fiber communications systems. Their proposal is composed of a technology to monitor OSNR in coherent optical communications at the expense of lower complexity and minimal bandwidth requirements, even at a higher symbol rate.…”

As the world advances into 5G networks, significant scientific research accomplishments are being conducted for a communication system that could further enhance the current limit of data transmission capacity. Currently, the communication systems with the highest data rate are optical fiber systems. Due to the recent advancement of coherent optical fiber communications by exploiting time, wavelength, phase, amplitude, polarization, and space, optical engineering can break the petabit barrier data rate. Thus, coherent optical fiber communications is a hot topic due to its very high data rate that could be applied or a requirement in 5G and big data analytics. This paper focuses on a comparative survey of the current applied fundamental techniques in fiber communication channels. These fundamental techniques that could be further studied and exploited to increase the bandwidth performance, decrease the error rate and energy consumption are coding, multiplexing, and equalization. At the end of this paper, a comparative result is discussed to explain the difference among the current techniques in the literature for the optical engineering community to improve collective coding, multiplexing, and equalization in coherent fiber systems.

“…Optical performance monitoring is an important aspect in the design of the next generation of optical communication systems [1]. Accurate measurement analysis needs to be developed to quantify the novel modulation schemes and to reliably predict the performance of optical coherent systems encoding information on both the amplitude and phase of the optical carrier for M-ary quadrature amplitude modulation (QAM) [2].…”
