“…23 After the striking demonstration of data transmission of soliton pulse beyond binary format by Fedor Mitschke et al, many researchers involved in planning solitons in their application specified to optical systems and networks (especially WIMAX recently). [24][25][26] The modern trend of soliton in data transmission could be realized from its use in passive optical networks for high-frequency radio-signal transmission using orthogonal frequency division multiplexing. But the trend of soliton transmission with different phase has attracted researchers for the practical convenience and to ensure deployment of coherent digital modulation schemes (ie, from previous generation of ON-OFF keying to phase keying).…”

Summary Here, we demonstrate the peculiar particle nature of soliton pulses with relative to phase, where the adjacent soliton pulses in a sequence attract and repel each other periodically for in‐phase and out‐of‐phase arrangement, respectively. This effect of soliton's interaction and repulsion is studied analytically by using perturbation theory approach. The study of soliton pair characteristics are mainly noted for different relative spacing (qo) between them and for different phase of launched soliton pulses. Following the analytical studies, we analyzed the effect in a 100 Gbps, single channel and uncompensated telecommunication system for different phased soliton sequences. Such that, the performance of the telecommunication system is characterized in terms of Q‐factor (Q) and bit‐error rate to realize the influence of phase on soliton pulses. The system was studied for 1 collision length (LD) of 123.36 km. It is seen that, for 100 Gbps system implemented with standard single mode telecom fiber, with soliton spaced at qo = 5.28, the in‐phase pulses interacted at 61.68 km, which has resulted in Q = 0 (bit‐error rate = 1). It is realized that for small‐phase introduction on soliton pulses, the system yielded fair Q demonstrating the non‐interaction at the Ip as the pulses deviate with respect to increasing phase values. But, it is also shown that large phase between pulses introduces more deviation, which results in overlapping of deviated pulses with adjacent pulses in sequence resulting in degradation of high bitrate system performance.

“…Novel technique for an increase of access points in a WDM-PON network integrated in a 100 GHz radio-over-fiber (RoF) was described by researchers in [11]. They used MRR (Microring Resonator) system to generate optical carriers for transmission of four OFDM (Orthogonal Frequency Division Multiplexing) signals and proved that transmission of four OFDM channels is feasible for a SSMF (Standard Single Mode Fiber) of 25 km of length.…”

Abstract-Passive optical networks are currently the most promising solution for access networks. Increasing bandwidth requirements and big data applications need a huge bandwidth. Nowadays, gigabit passive optical networks do not seem to be suitable for these purposes. This paper is focused on describing the development, parameters and needs for High Speed Access Networks (such as 100G EPON). The simulations with current wavelengths plans are presented. For simulations we used VPITransmissionMaker TM 9.7. Our goal was to create a rudimentary bidirectional PON system with one ONU and do several simulation scenarios by artificially increasing loss in a splitter for simulating more ONUs. Our following results consist of BER values and eye diagrams for each simulation scenario and proof that 100G EPON networks are most promising networks for the future. We proved that the 100G-EPON networks fully support the basic and currently used split ratios. We also created a two-way communication model and evaluated the obtained data from the bit error-rate and system reach point of view. The entire model was compared with the final version of NG-PON2.

A system of radio over free space optic (RoFSO) system using the multi‐optical carriers has been generated by the microring resonators integrating an add/drop filter. These obtained carriers have shown sufficiently stable for propagating in free space channels while experiencing very low dispersion. Moreover, this technique is appropriated for higher capacity that can be serviced in a system of wavelength‐division multiplexing (WDM) RoFSO, where there are 16 carriers created, where each carrier has 12.5 GHz free spectral range (FSR) and 220 MHz full‐width at half‐maximum (FWHM) and 8 orthogonal frequency division multiplex (OFDM) signals, then they separately modulated with 8 out of these 16 carriers. After the modulation, by utilizing an free space optic (FSO) antenna, all carriers have the optical multiplexing and transmission to a FSO channel. On the receiver side, the demultiplexing is performed and finally the performance of the system subsequently is analyzed by calculation of the constellation diagram and error vector magnitude (EVM).
