We reported an optimization method to improve Multi Slot Amplitude Coding (MSAC) optical fiber system performance. Simulation result clearly shows that optimum back to back BER performance is achieved when signal level spacing for upper level is higher than that of the lower level in order to compensate the signal dependent noise. In addition, we compare optimized system performance in terms of optical...
This paper reports a novel method on the probability of symbol error estimation for high speed Multi Slot Amplitude Coding (MSAC) technique in optically amplified communication system. The system setup is based on simple intensity modulation and direct detection scheme which is cost effective. In this proposed method, possibility of symbol error is estimated based on individual probability density...
In this paper a novel Mapping Multiplexing Technique (MMT) is demonstrated. Four channels, (4 × 10 Gbit/s) were successfully multiplexed and transmitted over a single wavelength, which can present a possible transmission rate of 40 Gbit/s per wavelength. The performance of MMT system is examined, with comparison to 40 Gbit/s RZ-OOK, NRZ-OOK and 4-ary techniques. This scheme features a receiver sensitivity...
An experimental setup of back-to-back 10kbps data transmission based on MSAC technique over fiber optic link with intensity modulation and direct detection (IM/DD) scheme is demonstrated for the first time. The signal waveform and signal spectrum from MSAC generator is observed. Signal spectrum observation shows that the first transition clock is at 3.33kHz. For optical MSAC signal transmission, the...
A new multi-slot and multi-level coding technique for high capacity communication system, known as Multi Slot Amplitude Coding (MSAC) is presented. This technique offers better flexibility in terms of defining the symbol based on time slot and signal level in order to generate more unique symbols as a line code with better clock information since all the symbols have zero level (return-to-zero) at...
