Compared with traditional wavelength division optical network, elastic optical network (EON) divides the network spectrum into smaller spectrum slots to improve the spectrum utilization, but the highquality spectrum division also complicates the routing and spectrum allocation (RSA) problem. Various strategies are proposed for reducing the RSA complexity and improving system traffic bearing capacity. However, previous RSA strategies do not consider the changing physical layer impairments that will also impact signal quality and even lead to violation of quality of transmission (QoT), the data cannot be transmitted correctly if the link state is degraded. Therefore, cross-layer optimization is desired, which means that different layer information is taken into account in the RSA strategy. In this paper, we propose a new link state-aware (LSA) RSA strategy to guarantee the QoT requirements under different link states. At first, the link state is evaluated based on chromatic dispersion (CD) and optical signal-to-noise ratio (OSNR), and a LightGBM model is exploited for CD and OSNR estimation. In LSA-RSA strategy, the link state is considered as a metric for qualified routing paths finding, and the link capacity is calculated based on the link state and used in spectrum allocation. Simulation results show that the average CD and OSNR estimation errors of the LightGBM model are 0.28ps/nm and 0.68dB, respectively. Under different link states and traffic loads, the LSA-RSA strategy can reduce traffic failure probability by more than 20%, and traffic load can increase 40Erlang when the bandwidth blocking probability equals 10%.

“…However, usually DMLs with modulation speeds beyond 10 Gbps suffer from a reduced extinction ratio (ER). Several schemes have been proposed to enhance the ER of the signals [11][12][13][14], such as using chirp managed lasers (CMLs), filtering the signal by a delay line interferometer (DLI) or micro-ring resonator (MRR). A silicon based MRR has a small footprint and is compatible with complementary metal-oxide-semiconductor (CMOS) technology allowing potential integration with other optical/ electrical devices, which is a promising technique for the cost-effective implementation of compact transmitters for access network applications.…”

“…In this paper, we propose, for the first time, a SDM-PON scheme based on a high-count multi-core fiber (HC-MCF) achieving a high splitting ratio and large transmission capacity at the same time. Instead of using MZM, an off-the-shelf DML modulated with 25/28 Gbps signals is used [14], and the ER is improved by using a polarization-diversity micro-ring resonator (PD-MRR) [15]. SDM-PON with both symmetric and asymmetric architectures are proposed for different scenarios, such as 25/100 Gbps US/DS capacity for residential subscribers and 100/100 Gbps US/DS capacity for enterprises, respectively.…”

“…In this paper, we propose a bidirectional SDM-WDM-PON system based on commercial DMLs [15] which can be used to enhance the extinction ratio of the modulated 25 Gb/s signal. In addition, by using a MCF for bidirectional transmission, not only is the transmission capacity increased, but also colorless optical network units (ONUs) can be achieved, allowing the same optical line terminals (OLTs) and OUNs to be employed regardless of wavelengths.…”
