100 Gb/s optical access based on optical orthogonal frequency-division multiplexing

Energy-efficiency improvements for optical access

“…The orthogonal frequency division multiple access PON (OFDMA-PON) recently gained interest in the research community as an alternative solution for next generation PONs [9] [10]. OFDMA-PON employs a large number of subcarriers overlapping in spectrum, but not interfering with each other because they are orthogonal, hence achieving high spectral efficiency.…”

300 Gb/s IM/DD based SDM-WDM-PON with laserless ONUs

“…By using wavelength-division multiplexing (WDM), a hybrid WDM-TDM-PON has been demonstrated, which can stack multiple TDMPONs [5,6]. In addition, many other techniques have also been proposed for a PON system, such as orthogonal frequency division multiplexing (OFDM), ultra-dense WDM and coherent detection [7][8][9][10][11]. In order to further increase the capacity of a PON system, space-division multiplexing (SDM) has been introduced to utilize multiple spatial channels for data transmission through a single fiber [12][13][14][15][16][17].…”

Implementing a Long Reach Upstream and Downstream Data rate 100Gbps WDM-PON by using Directly Modulated RSOA

“…The explosion of the Internet coupled with new video centric services has increased the demand for high bandwidth in access networks. Fiber to the home, based on a PON due to its high bandwidth, cost sharing of infrastructure, and absence of active components, is considered as a good solution to this demand [1]. Services such as IP high-definition video delivery, Voice-over-IP, social networking and cloud computing have pushed the demand for bandwidth even beyond what is achievable with today's gigabit PONs.…”

“…The objective of this work is to implement and propose low cost architectures for high speed performance of Passive Optical Network. [1] Due to the recent standardization activities of 100 Gigabit Ethernet (100 GbE), there have been growing interests in the 100-Gb/s passive optical network (PON) [1]. For example, it has been already demonstrated that 100-Gb/s PON can be realized by using the optical orthogonal-frequency-divisionmultiple access (OFDMA) technique [2] [4].…”
