چکیده
We experimentally demonstrate 200 Gb/s/ $\lambda $ upstream coherent passive optical network (PON) using polarization division multiplexed (PDM) pulse amplitude modulation 4-level (PAM4) signal with detection. The 50 GBaud PDM-PAM4 is generated a low cost C-band electro-absorption modulated laser (EML), polarization-division multiplexing emulator and semiconductor amplifier (SOA). A power budget of 29.4 dB achieved for 25 km single mode fiber (SMF) transmission class-40 integrated receiver (ICR) at the line terminal (OLT).

Beyond 100 Gb/s Optical Transmission Based on Polarization Multiplexed Coded-OFDM With Coherent Detection
p Abstract—We propose a coded-modulation scheme suitable for beyond 100 Gb/s transmission and 100 Gb/s Ethernet. It is based on polarization multiplexed coded-orthogonal frequency division multiplexing (OFDM). By using 32-QAM-based polarization multiplexed coded-OFDM, we are able to achieve the aggregate rate of 100 Gb/s, while the OFDM signal bandwidth is only 10 GHz, resulting in a spectral e...

In this paper, we propose and experimentally investigate a simple self-injection Fabry-Perot laser scheme on each optical network unit (ONU) for 10 Gbps TDM passive optical networks (PONs). Based on the proposed four wavelength-multiplexed 2.5 Gbps lasers, the 10 Gbps uplink traffic can be achieved at a cost-effective way. The network architecture and performance have also been analyzed and dis...

We propose a spectral efficient radio over wavelength division multiplexed passive optical network (WDM-PON) system by combining optical polarization division multiplexing (PDM) and wireless multiple input multiple output (MIMO) spatial multiplexing techniques. In our experiment, a training-based zero forcing (ZF) channel estimation algorithm is designed to compensate the polarization rotation ...
متن کاملPolarization-multiplexed rate-adaptive non-binary-quasi-cyclic-LDPC-coded multilevel modulation with coherent detection for optical transport networks.
In order to achieve high-speed transmission over optical transport networks (OTNs) and maximize its throughput, we propose using a rate-adaptive polarization-multiplexed coded multilevel modulation with coherent detection based on component non-binary quasi-cyclic (QC) LDPC codes. Compared to prior-art bit-interleaved LDPC-coded modulation (BI-LDPC-CM) scheme, the proposed non-binary LDPC-coded...
