In this paper, we propose a cost effective wavelength reused mode-division-multiplexing (MDM) system for high speed symmetrical bidirectional mobile fronthaul application. At the base band unit (BBU) pool, one of the spatial modes is used to transmit signal carrier while the others are used for downstream signal channels. At the remote radio unit (RRU) side, the signal carrier is firstly mode demultiplexed...
We propose a cost-effective, energy savings WDM-MDM PON scheme utilizing self-homodyne detection for high-speed/capacity access network with low mode-crosstalk FMF and MUX/DEMUX. A proof of concept 4×40 Gb/s OFDM signal over 55 km FMF with error free operation was experimentally demonstrated.
A cost-effective mode-division-multiplexing and time-division-multiplexing passive optical network (MDM-TDM PON) utilizing a self-coherent detection for upstream signal at optical line terminal (OLT) and a high-gain reflective semiconductor optical amplifier (RSOA) as an optical amplifier for a downstream signal at optical network units (ONUs) to enhance bidirectional power budget is proposed. Meanwhile,...
We propose and experimentally demonstrate an asymmetrical TWDM-PON scheme with 4×25-Gb/s downstream DSB OFDM modulation and 4×10-Gb/s upstream OOK Modulation. More than 35.5-dB power budget for bidirectional transmission is demonstrated.
In this letter, we evaluate the symbol error probability of orthogonal frequency division multiplexing (OFDM) with M-ary (M>4) phase shift keying (MPSK) impaired by carrier frequency offset (CFO). A signal space decomposition (SSD) approach is proposed for additive white Gaussian noise (AWGN) channels, and then the symbol error rate (SER) performance is expressed as the sum of an infinite series...
