Abstract 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.

1 Introduction The data transmission industry demands a major rise in the bandwidth of the communication channel. The huge demand of high speed internet for enormous data transmission makes the tremendous growth in bandwidth for dense wavelength division multiplexing [(DWDM)] system (Kumar and Goyal 2017; Nair et al. 2018). Transmission with DWDM channels were put into exercise as the experienced use of fiber bandwidth as cost-effective * Aruna Rani [email protected] 1

and reliable for transport data bits in long haul metro networks. The DWDM repeaters on the transmitting and receiving channels were restricted due to cost and complexity of system. So the competent exercise of fiber bandwidth was to exploit the costly network resource, for that several substitutes have been tried in combination with DWDM. Now to handle with dynamically fluctuating traffic requires the scheme reconfigurable OADM were devised, which can alter the selected channel routing to the optical networks. It decreases requirement for optical-to-electrical-to-optical (O-E-O) translations. An optical transport network (OTN
