“…A number of previous studies have confirmed the feasibility of AMCC in WDM-PON. For example, AMCC is used to achieve wavelength control in WDM-PON systems [17]- [21]; an AMCC-managed WDM-PON system is proposed for ONU activation, wavelength adjustment, and monitoring in [22]- [23]; and AMCC can be used to reduce the power penalty [24]. In addition to exploring the application scenarios of AMCC, the generation and extraction of AMCC signal is also an interesting research topic.…”

The auxiliary management and control channel (AMCC) is an extra channel transmitting control and management signal to not change the GPON frame and reduce the PON system latency. In this paper, we demonstrate AMCC for control information transmission in a coherent frequency division multiplexing passive optical network (FDM-PON). In our work, we introduce the multiplication scheme of digital AMCC signal superimposition theoretically and show that the multiplication scheme can maintain a high signal-to-noise ratio (SNR) for the main signal. Thus, we apply the multiplication scheme for the AMCC signal superimposed to the coherent FDM-PON. In addition, we propose a novel extraction algorithm without interference cancellation to detect the AMCC signal. A 4-band coherent FDM-PON system with a total data rate of 100 Gbps and a 24 Mbps non-return-to-zero (NRZ) signal is demonstrated both through simulation and experiment. Index Terms-Coherent frequency division multiplexing passive optical network (FDM-PON), Auxiliary management and control channel (AMCC).

“…It is unsuitable for business users who require low latency. Therefore, to enable PON systems to accommodate multiple services, employing the wavelength division multiplexing (WDM) scheme has been recommended alongside the TDM scheme [1]. In the WDM-PON system, multiple wavelengths are assigned to each user [2].…”

“…In this way, the access networks with higher flexibility and reliability should be essential issue for communication. Hence, the integrated optical wired and wireless access technologies, will be the promising candidate, have been studied recently [9][10][11]. However, to achieve higher capacity for data transmission, wavelength-divisionmultiplexing (WDM) access technology could be the better choice [12,13].…”

Free Space Optical Communication in Long-Reach Unidirectional Ring-Architecture Fiber Network

In the work, a ring-constructed wavelength-division-multiplexing (WDM) access system for delivering multiple free space optical (FSO) wireless signals is investigated. To reach the FSO transmission through single-mode fiber (SMF) connection, the optical wireless unit (OWU) and remote OWU are designed in the WDM network. The downstream and upstream WDM FSO channels could be transmitted in unidirectional propagation with the same wavelength. Hence, the presented ring-based WDM network not only can transmit the FSO signal, but also can circumvent the Rayleigh backscattering (RB) interferometric beat noise. In addition, according to the experimental results, the SMF and FSO transmission lengths can reach 50 km and 500 to 1000 m at the forward error correction (FEC) level without using optical amplification and dispersion compensation, respectively, when four WDM wavelengths are exploited experimentally for demonstration. INDEX TERMS Free space optical (FSO); Rayleigh backscattering (RB), WDM Access, OOK modulation, Ring-architecture.
