In this paper, different detection technique is presented through bit rate 1Gbps. Advanced modulation technique is used for enhancing the performance of optical access network. Differential phase shift keying (DPSK) has significant attention for the researcher during last two decades. Optisystem version 12 has been employ for investigate the transmission capability of the hybrid system. The comparison...
This research work focuses to design Hybrid OCDMA over WDM system with advance modulation techniques DPSK which will improve the performance for long distance fiber length. Hybrid system merges with different types of techniques like OCDMA and WDM. Modified double weight (MDW) code is proposed as the signature address code. Multiuser interference and increase the bit-error-rate might be condense satisfactory...
This paper presents five signal formats of return to zero (RZ), non-return to zero (NRZ), chirped return to zero (CRZ), soliton and duobinary in a transmission link. All the signals are compared in terms of its original and conversion to carrier suppressed. Long haul of 3880km is used in original transmitter while 770km used for conversion transmitter. The signal converter utilizes the semiconductor...
