  Quantum repeater networks play a crucial role in distributing entanglement.
Various link architectures have been proposed to facilitate the creation of
Bell pairs between distant nodes, with entangled photon sources emerging as a
primary technology for building quantum networks. Our work advances the
Memory-Source-Memory (MSM) link architecture, addressing the absence of
practical implementation details. We conduct numerical simulations using the
Quantum Internet Simulation Package (QuISP) to analyze the performance of the
MSM link and contrast it with other link architectures. We observe a saturation
effect in the MSM link, where additional quantum resources do not affect the
Bell pair generation rate of the link. By introducing a theoretical model, we
explain the origin of this effect and characterize the parameter region where
it occurs. Our work bridges theoretical insights with practical implementation,
which is crucial for robust and scalable quantum networks.
