AB  - Most of today’s optical networks are based on
reconfigurable optical add/drop multiplexers (ROADMs) nodes.
However, current ROADM architectures have poor scalability
due to limitations on the wavelength selective switches dimension.
Hence, due to the constant increase in data traffic and the demand
for more dynamic and flexible networks, current architectures
might become a bottleneck in the foreseen large-scale ROADMs.
In this work, several architectures for large-scale ROADMs
proposed to overcome this bottleneck are studied in terms of
hardware cost and in-band crosstalk generation and compared
with large-scale ROADMs built with conventional architectures.
We show that ROADMs based on a sub-system modular architecture,
also known as interconnected architecture, exhibit a
significant hardware cost reduction in relation to conventional
architectures and are also advantageous regarding the in-band
crosstalk generation. Moreover, in this work, an analysis of
optical filtering effects, amplified spontaneous emission noise
and in-band crosstalk impact in the performance of an optical
network, with nodes based on the interconnected architecture, is
performed through Monte-Carlo simulation.
