“…Along the length of an optical link can occur numerous defects which are caused by random noise accumulated, so the use of regeneration is essential to extend the transmission distance of the digital signal in addition to the limitations [8]. Therefore, the removal or remodeling those noises in the optical domain require the use of non-linear optical materials, optical fiber is excellent.…”

“…The Highly non-linear fibers based on standard silica with a nonlinear coefficient of ~20 1 / −1 or other types of materials and also with photonic crystals, both of which have required lengths in the order of tens or hundreds of meters [8], have been used in 2R regenerators or 3R. Another interesting type of fiber is the fiber with dispersion compensation, which has as main characteristic, a negative dispersion, whose function is to compensate for the effects of phase displacement, caused by the color dispersion of the SMF link used in the same network.…”

This paper aims to present a fiber optic telecommunications network design capable of suppressing noise and improving the quality of the transmitted signal through the self-phase modulation effect in a highly nonlinear fiber (HNLF), thus allowing the regeneration 2R (Reamplification and Reshaping) in a totally optical way. For a distance of up to 300 km of SMF, the values of factor Q = 6, BER = 10 -9 and OSNR = 13.5 dB were found. The project was developed and simulated in Optisystem software. The results confirm that the proposed 2R regenerator was efficient.

“…Optical signals propagating in fiber-optic transmission systems are impaired by various sources, which limit their transmission distance [1]. All-optical regeneration is a valuable functionality that can potentially extend the distance of digital-signal transmission beyond this limitation in a larger network.…”

Simultaneous regeneration of four high-speed (160 Gbit/s) wavelength-division multiplexed (WDM) and polarization-division multiplexed (PDM) signals in a single highly nonlinear fiber (HNLF) is demonstrated. The regeneration operation is based on four-wave mixing in HNLF, where the degraded data signals are applied as the pump. As a result, the noise on both '0' and '1' levels can be suppressed simultaneously in our scheme. The stimulated Brillouin scattering (SBS) from the continuous wave (CW) is suppressed by cross-phase modulation (XPM) from the data pump, relieving the requirement of external phase modulation of the CW light. Mitigation of the inter-channel nonlinearities is achieved mainly through an inter-channel 0.5 bit slot time delay. Bidirectional propagation is also applied to relieve the inter-channel four-wave mixing. The multi-channel regeneration performance is validated by bit-error rate (BER) measurements. The receiver powers at the BER of 10 −9 are improved by 1.9 dB, 1.8 dB, 1.6 dB and 1.5 dB for the four data channels, respectively. ©2014 Optical Society of America

“…To date, numerous techniques for optical intensity stabilization including optical limiters, optical reshaping techniques and optical regenerators have been evaluated [21][22][23]. Among them, the techniques that are based on self-phase modulation (SPM) methods are more stable, having less complexity and supporting higher bit rates, i.e.…”

We have numerically implemented a receiver side all-optical signal processing method, i.e. optical backward propagation (OBP), by dispersion compensating fiber (DCF) and non-linear compensator (NLC) devised by effective negative Kerr non-linear coefficient using two highly non-linear fibers (HNLFs). The method is implemented for the post-processing of fiber transmission impairments, i.e. chromatic dispersion (CD) and non-linearities (NL). The OBP module is evaluated for dual-polarization (DP) m-ary (m=4,16,32,64,256) quadrature amplitude modulation (QAM) in 112 Gbit/s coherent transmission over 1200 km standard single mode fiber (SMF). We have also investigated an intensity limited optical backward propagation module (IL-OBP) by using a self-phase modulation-based optical limiter with an appropriate pre-chirping to compensate for the intensity fluctuations in the transmission link. Our results show that in highly non-linear sensitive 256QAM transmission, we have observed a 66% increase in the transmission distance by implementing IL-OBP as compared to conventional OBP.
