“…Each channel has two polarization-multiplexed 107-G bit/s signals that were coded using the Quadrature Amplitude Modulation (QAM) scheme [20]. The greatest capacity Discrete Multi-tone Modulation (DMT)signal transmission across 2.4-km SMF with the BER under SD-FEC constraint of 2.4 X10 -2 was accomplished using a four-channel WDM 256.51Gbps 16-QAM-DMT short-reach optical-amplifier-free interconnection [21].…”

In this article, the performance of a fixed grid network is examined for various modulation formats to estimate the system's capacity and spectral efficiency. The optical In-phase Quadrature Modulator (IQM) structure is used to build a fixed grid network modulation, and the homodyne detection approach is used for the receiver. Data multiplexing is accomplished using the Polarization Division Multiplexed (PDM) technology. 100 Gbps, 150 Gbps, and 200 Gbps data rates are transmitted under these circumstances utilizing various modulation formats. Various pre-processing and signal recovery steps are explained by using modern digital signal processing systems. The achieved spectrum efficiencies for PM-QPSK, PM-8 QAM, and PM-16 QAM, respectively, were 2, 3, and 4 (bits/s)/Hz. Different modulation like PM-QPSK, PM-8-QAM, and PM-16-QAM each has system capacities of 8-9, 12-13.5, and 16-18 Tbps and it reaches transmission distances of 3000, 1300, and 700 kilometers with acceptable Bit Error Rate (BER≤ 2× 10-3 ) respectively. Peak optical power for received signal detection and full width at half maximum is noted for the different modulations under a fixed grind network.

“…To the best of our knowledge, 10.44 Gb/s 16 to 256-QAM OOFDM real-time system with an SE of 4.85 b/s/Hz over 20 km standard single-mode fiber (SSMF) using HD-FEC is the highest bit rate [13] that has been reported in a low-cost real-time IM/DD single-band singlewavelength OOFDM PON system. There are other systems with higher bit rates where the processing is done offline [6][7][8]17], or use very expensive components [18], or frequency-division multiplexing [19,20], or wave-division multiplexing [21][22][23].…”

This paper presents the hardware architecture of an OFDM receiver suitable for optical communications. The receiver has been implemented in an FPGA device and used to demonstrate experimentally an optical OFDM transmission in a passive optical link with a directly modulated DFB laser and DAC/ADC at 5 GS/s. A bit rate of 20.37 Gb/s is achieved using an OFDM signal with subcarrier modulation format up to 512-QAM, it has been successfully transmitted over 10 km SSMF with a spectral efficiency of 8.38 bit/s/Hz.
