Abstract: The 'application 'of 'transmission 'through 'Optical 'Fiber 'is 'possible 'in 'each 'and 'every 'area 'where 'transferring 'of 'information 'is 'required 'from 'one 'location 'to the other. 'However, today’s 'infrastructure 'of 'telecommunications 'relies 'on 'Data 'transmission 'through 'Optical 'Fibers, 'because 'of 'their 'low 'attenuation 'and 'higher 'bandwidth. Now 'a 'days 'the 'need 'of 'higher 'data 'rates 'of '100Gbit/s 'and 'above 'that 'has 'been 'increased 'in 'the 'metro, 'regional, 'enterprises, 'access 'and 'for 'long 'haul 'markets 'also. 'Therefore, 'it 'is 'the 'required 'to 'take 'the 'transmission 'systems 'to 'the 'next 'level 'to avoid the overloading of the Optical Infrastructure than 'its 'current 'capacity. To fulfill 'increased 'demand 'of 'bandwidth 'in 'Broadband 'services 'one 'of 'the 'most 'trusted 'technology 'is 'Orthogonal 'Frequency 'Division 'Mulitplexing. ' Orthogonal 'Frequency 'Division 'Mulitplexing 'is 'becoming 'highly 'popular 'among 'the 'community 'of 'Optical 'Communication, 'specially 'for 'the 'features 'it 'provides 'in 'Long 'haul 'transmission 'Format 'in 'Direct 'and 'Coherent 'detection.OFDM 'is 'also 'considered 'for 'its 'ability 'to 'overcome 'many 'restrictions 'of 'Optical 'Fiber 'communication 'such 'as 'polarization 'mode 'dispersion '(PMD) 'and 'chromatic 'dispersion '(CD).However, 'integration of 'the 'coherent 'optical 'OFDM 'with 'Wavelength 'Division 'Multiplexing '(WDM) 'systems 'has 'advantages 'in 'the 'transmission 'system 'like '- 'higher 'bandwidth, 'a 'high 'spectral 'efficiency 'and 'significant 'data 'rates. 'Also 'the 'WDM 'systems 'can 'help 'to 'enhance ' 'data 'rate 'and 'capacity 'by using 'multiple 'wavelengths 'over 'a 'single 'fiber. The Objective of this research is to focus on the implementation and to perform anlaysis of higher data rates using Direct and Coherent Optical OFDM for large distance transmissions. 'This 'study begins with a 'single 'user 'and then extends 'to 'the 'implementation 'of 'the 'OFDM - WDM 'system 'for achieving a transfer rate of 100Gbits/s. 'Optisystem 'simulation 'tool 'is 'used for 'design 'and 'implementation of 'the 'system. 'The 'system 'used is for 'carrying 'range 'of 'data 'starting 'from '10Gbits/s by using 'direct 'detection 'to '100Gbits/s when 'OFDM-WDM being used, 'the modulation type used is QAM 'for 'the 'OFDM 'signal, and at the transmitter I/Q modulation is deployed, while Coherent 'and Direct 'detection are 'used 'at 'receiver end. 'To study the System’s Performance and Quality of Signal three parameters have been tested which are - Q Factor, the bit error rate and eye diagram.
Keywords: Direct Detection OFDM(DD-OFDM), Coherent Detection OFDM(CO-OFDM), Integration of WDM with CO-OOFDM for long haul high data rate transmission.
