“…Owing to the advantages of bend insensitivity, easy installation and robustness to the electromagnetic interference, the step-index polymer optical fiber (SI-POF) with a large core diameter becomes a popular transmission medium in short range communications, and can be used in a variety of applications [1][2][3][4][5]. Additionally, in the POF networking, the discrete multi-tone (DMT) modulation [6][7][8] with a bit-loading algorithm has been an efficient solution to maximize the system capacity [9].…”

Abstract:In polymer optical fiber (POF) systems, the nonlinear transfer function of the resonant cavity light emitting diode (RCLED) drastically degrades the communication performance. After investigating the characteristics of the RCLED nonlinear behavior, an improved digital look-up-table (LUT) pre-distorter, based on an adaptive iterative algorithm, is proposed. Additionally, the system parameters, including the bias current, the average electrical power, the LUT size and the step factor are also jointly optimized to achieve a trade-off between the system linearity, reliability and the computational complexity. With the proposed methodology, both the operating point and efficiency of RCLED are enhanced. Moreover, in the practical 50 m POF communication system with the discrete multi-tone (DMT) modulation, the bit error rate performance is improved by over 12 dB when RCLED is operating in the nonlinear region. Therefore, the proposed pre-distorter can both resist the nonlinearity and improve the operating point of RCLED.

“…More recently, multicarrier modulation techniques have been enrolled to explore the throughput in POF channels [1,5,6]. Derived from the generally well-known orthogonal frequency division multiplexing (OFDM) in wireless communications [7], discrete multitone (DMT) is a baseband version of the multicarrier modulation technique, which has already been used for asymmetric digital subscriber line communications [8].…”

“…Furthermore, DMT modulation requires high bit resolution of digital-to-analog converters (DACs) and analog-to-digital converters (ADCs) [22]. In most POF experiments adopting off-line processing, an arbitrary waveform generator (AWG) and a digital storage oscilloscope (DSO) were used to meet the requirements of high sampling rate and bit resolution of the DAC/ADC [1,5,[12][13][14][15][16][17][18]. It is worth noting that the quantization noise due to the limited effective number of bits (ENOB) in the ADC of the DSO is a significant limitation of overall performance in optical communications [23].…”

“…However, in an experimental POF DMT system, the ENOB is quite lower than the DAC/ADC number of bits and the low-frequency subcarriers have a very high SNR, which requires more bits in the ADC. Although oversampling is usually used in the DMT transmission over POF [5,12,13], none of them indicates the relationship between the ENOB and the oversampling. The optimal oversampling rate is also not investigated in the POF system.…”

In this paper, we propose an overall optimization of discrete multitone (DMT) transmissions over polymer optical fiber (POF). The optimization is carried out from both a theoretical and experimental approach. At first, the parameters of the POF channel characteristics, resonant cavity light emitting diode (RC-LED) dynamic nonlinearity performance and analog-to-digital converter effective number of bits (ENOB), in our digital storage oscilloscope are measured. From the measured results, we investigate the channel capacity of a 50 m step-index POF system. Then the optimal DMT bandwidth is theoretically derived. We also optimize the system with different experimental setups. The optimal cyclic prefix length and RC-LED optimal working current are given. The ENOB can be improved by oversampling and averaging. The optimal oversampling factor is discussed. Furthermore, a joint DMT clipping and subcarrier number optimization is synthetically investigated. Based on the proposed approaches, an optimized DMT gigabit transmission over a real 50 m POF channel employing low-cost components is presented. Finally, a methodology for the practical design of the DMT transmission over POF is concluded.

“…This is because POF has the capability of providing safety and "plug and play" features. Bit rate as high as 7.6 Gbps has been achieved over 10 m, 1 mm diameter POF with discrete multitone modulation [4]. On the other hand, due to the added mobility feature, wireless PAN is even more attractive and the IEEE 802.15 task group has standardized the use of Bluetooth and Zigbee technologies [5,6].…”

Ultra-broadband indoor optical wireless communication system with multimode fiber

In this paper we experimentally demonstrate an ultra-broadband indoor full-duplex WDM optical wireless communication system with multimode fiber. The multimode fiber is used because it is employed in most of the already installed in-building fiber distribution networks. Simultaneous error-free (BER<10(-9)) transmission of 4×12.5 Gbps downlink and 800 Mbps uplink has been successfully demonstrated. The experimental results show that, although the use of multimode fiber will induce ~2.4 cm reduction in the maximum error-free beam footprint in the downlink, the bit rate of the uplink can be much higher compared to the system with single-mode fiber.
