An all-optical clock recovery has been demonstrated numerically with single and double ring microring resonators from 40 Gbit/s return-to-zero on-off keying optical signal. The influence of device cascadability on amplitude fluctuation caused by patterning effects of extracted clock values have been evaluated. Open source simulation toolbox Optilux was used for simulations. The results show that these fluctuations related to patterning effects are considerably reduced after processing with five cascaded single ring microring resonators.

“…OptSim 5.2 simulation software was used to obtain the results introduced in this article. As experience shows, it is capable of handling complex simulations of multichannel optical transmission systems and of ensuring high accuracy results without high performance requirements for the hardware it is operating on [9]- [11]. In order to assess the impact of channel spacing on the performance of EDFAs, a simulation model of a 9.953 Gbps WDM transmission system with non-return to zero intensity on-off keying modulation (NRZ-OOK) transmission distance of 150 km and an in-line EDFA introduced.…”

The article investigates dependence of EDFA performance on its operating conditions. First of all, the impact of changes in channel spacing on the quality of the amplifier signal and on the desired EDFA configuration is observed – three different values of channel spacing are considered – 37.5 GHz, 50 GHz and 100 GHz. Afterwards, the impact of EDFA positioning on the quality of the amplified signal and the desired configuration is assessed. Three different EDFA positioning scenarios are considered – when the EDFA is used as a power booster, as an in-line amplifier and as a preamplifier. In all cases, such configuration of the EDFA is found that can ensure bit-error ratio (BER) values below 1·10−9 in all channels of the system. To assess the performance of the amplifiers, power penalty values are obtained in respect to identical transmission systems but without amplification.

“…A variety of telecommunications architecture have been introduced in the recent years, but only one which shows the potential to achieve this obstacle in telecommunication fiber which known as DWDM for longdistance data transmission. The DWDM has much simpler design and robust [1], [2]. This system architecture can meet the rapidly growing population demand usage like video live streaming, online gaming, virtualization (VR) and much more.…”

This paper presents on the design and analysis of Dense Wavelength Division Multiplexing Passive Optical Network (DWDM-PON) which is the upcoming trend technology nowadays to transmit up to 40 Gbps data. Various modulation techniques such as Non-Return Zero (NRZ), Return-Zero (RZ) and duo binary coding are simulated in this DWDM-PON. Using OptiSystem software, DWDM-PON is designed and simulated for 32 channels with spacing of 100 GHz and bit rate of 10 Gbps. An Erbium Doped Fiber Amplifier (EDFA) and Dispersion - Compensating Fiber (DCF) is deployed in the DWDM design. It is found that duo binary modulation technique gives the best performance with minimum BER of 2.66x10-19. From the simulation result, it also found that the proposed DWDM PON design is suitable to be deployed for current network.
