AB  - Metro-aggregation networks are undergoing
a major transformation to accommodate the exponential
growth in data traffic, requiring scalable and
cost-effective solutions. On the transceiver side, coherent
pluggable optics are set to be the dominant transmission
solution, in view of the cost, footprint, power
consumption, and interoperability benefits. On the line
system side, filterless optical networks (FONs) offer
architectural simplicity and potential CAPEX savings,
despite introducing challenges such as spectrum waste,
channel power imbalance, and increased impact of outof-
band noise. Conversely, reconfigurable optical adddrop
multiplexer (ROADM) architectures based on
wavelength blocker (WB) using wavelength selective
switch (WSS) mitigate these limitations, albeit at the
expense of higher insertion loss (IL) and complexity. A
comprehensive comparative analysis of FON and WBbased
ROADM architectures considering a horseshoe
topology in metro-aggregation network scenarios is
presented. Customized algorithms to optimize optical
amplifier (OA) settings are proposed for each architecture.
The resulting network design framework is used
to characterize the scalability of metro-aggregation
networks based on each architecture when considering
different network sizes and offered capacity per node.
Results highlight that adopting higher-performance
multi-source agreement (MSA) transceivers and implementing
tailored OA settings optimization mitigates
the limitations of FON architectures. Moreover, the
study demonstrates that the most suitable solution, in
terms of transceiver type and line system architecture
combination, depends on the network size and target
capacity.
