摘要

ROADM technology has reformed optical networking and an intimate part of recent optical communication offering enormous bandwidth for data conveyance at least expense. In this paper, reconfigurability in the dense wavelength division multiplexing system is analyzed with the placement of digital switches by varying the bit rate from 10 to 40 Gbps by adding and dropping certain wavelengths. The performance of the dense wavelength division multiplexing system is characterized in terms of the quality factor, bit error rate and optical signal to noise ratio. It is observed that the signal can be communicated over a distance of 780 km with 16 channels, 420 km with 32 channels and 300 km with 64 channels having a low input power of -10 dBm with an acceptable bit error rate and quality factor. Furthermore, the performance of the system is calculated by varying the number of fiber spans with input power of -10 dBm with a bit rate of 40 Gbps. This structural design permits for remote traffic provisioning at the wavelength level in network node, operation cost reduction, better consumption of communication bandwidth, simplification of network design and implementation.
