Nowadays, Dense Wavelength Division Multiplexing (DWDM) has become a key component of the world’s communications infrastructure. The significant improvement in high-speed electronics and optical components, and multi-level modulation formants and coherent receiver technology has enabled high rate data transmission. DWDM promises to increase the bandwidth per fiber as the bit rate and the number of wavelengths increase. According to ITU-T G.694.1, mostly used DWDM systems have been operating with 40, 80 and 120 wavelengths, and with advanced modulation schemes and coherent receiver technology along better dispersion management, a single wavelength in today’s world can able to transmit upto 100Gbps; thus total maximum bandwidth is an amazing 4Tbps, 8Tbps, and 12Tbps, respectively. However, today’s commercial systems have a fiber transmission requirement for around 10Tbps, and globally demand has been increasing about 35% to 45% per year. Hence, to meet this increasing demand transponders transmission rate must have to be increased. This paper reviews the progress and techniques used to increase wavelength throughput from 2.5Gbps to 100Gbps, and investigates the challenges to transmit data beyond 100Gbps in a single operational cycle.
