“…In 2022, a high transmission capacity of up to 400 exabytes per month will be required to deal with worldwide internet traffic, and by 2023 the number of internet users increases to 5.3 billion, i.e. 66% of the global population [4]. To cope with bandwidth-hungry applications, the telecommunications industry must surely develop the next-generation optical communications technology.…”

Few-mode fibers have been used in contemporary communication with mode multiplexing and space-division-multiplexing techniques to enhance the capacity crunch in recent communication links. The design parameters of the proposed fiber are predicted through machine learning-based inverse design approach, using regression model. The proposed few-mode fibre profile parameters are predicted with an accuracy of 99.95% to guide five to ten modes with weak coupling among the guided modes. In second phase of this work, the authors used a finite difference method-based solver to obtain the modal characteristics of the proposed fibre with predicted parameters for six guided modes, namely, LP01, LP11, LP21, LP31, LP41, and LP51. The numerical simulation results show that the predicted profile parameter maximizes effective mode-area and minimizes the inter-channel crosstalk for mode division multiplexing transmission over C-band. Besides this, the proposed ring-core few-mode fiber also exhibits nearly zero-dispersion for LP01 mode at 1550 nm along with low dispersion for other higher-order modes. Finally, an intensity-modulation and direct-detection mode multiplexed transmission link without erbium-doped fiber amplifier is established with six-spatial channels over 50 km and an attenuation of 0.18 dB/km to achieve minimum bit-error-rate of 4.45×10 −9 .

“…The decryption also requires the synchronization between the sent and received signal. The authors in [10] proposed chaosmasking encryption techniques for long distance communication, where advanced digital signal processing is used to decrypt the signal. However, this scheme does not provide sufficient security if high confidentiality is required.…”

The high capacity and low latency of optical connections are ideal for supporting the current and future communication services, including 5G and beyond. Although some of those services are already secured at the packet layer using standard stream ciphers, like Advanced Encryption Standard (AES) and ChaCha, secure transmission at the optical layer is still not implemented. To secure the optical layer, cryptographic methods need to be fast enough to support high-speed optical transmission and cannot introduce significant delay. Moreover, methods for key exchange, key generation and key expansion are required, which can be implemented on standard coherent transponders. In this paper, we propose Light Path SECurity (LPsec), a secure cryptographic solution for optical connections that involves fast data encryption using stream ciphers and key exchange using Diffie-Hellman (DH) protocol through the optical channel. To support encryption of high-speed data streams, a fast, general purpose Pseudo-Random Number Generator (PRNG) is used. Moreover, to make the scheme more secure against exhaustive search attacks, an additional substitution cipher is proposed. In contrast to the limited encryption speeds that standard stream ciphers can support, LPsec can support high-speed rates. Numerical simulation for 16-QAM, 32-QAM and 64-QAM show that LPsec provides sufficient security level while introducing negligible delay only.

As optical communication system deployment is expensive, and reconfiguration is occasionally impossible or costly, system experiments and simulations have become necessary for predicting and optimizing system performance. OptiSystem is a cutting-edge optical communication simulation tool for designing, testing, and optimizing nearly any kind of optical connection in the physical layer of a wide range of optical systems. This paper proposed single-mode fiber as a transmitting medium for encrypted data. We examined a Dense Wavelength Division Multiplexing (DWDM) system with eight channels operating at 10 Gbps. A large capacity 80 Gbps system with a frequency range of 193.1 THz and a Non-Return to Zero (NRZ) modulation format is analyzed in the proposed design. The results show that the proposed scheme can effectively transmit secure data based on new chaotic systems. MATLAB is used to implement the encryption and decryption processes, whereas some statistical analysis and OptiSystem 7 are used to assess the signal transmission in optical fibers. The performance of the proposed system is evaluated in terms of Quality Factor (Q-factor), Bit Error Rate (BER) and eye .diagram. It is observed that by varying the input power from -15 dBm to 15 dBm with step of 5 dBm, a low BER with a high Q-factor has the best values at 5 dBm of input signal power , where the maximum Q-factor is 42.2797, and the minimum BER of 0 is obtained for 100 km of optical fiber length. A slightly degradation in system performance was abserved with increasing of fiber length from 50 km to 125 km.
