 \nThe throughput  is an important performance metric of entangled qubit di
 stribution quantum networks, and is characterized by the number of distrib
 uted entangled pairs of entanglement bits per second (ebps). It is measure
 d over physical connections using specialized instruments, including photo
 nic entanglement sources and single photon detectors. Extensive theory has
  been developed to estimate the entangled qubit capacity of quantum channe
 ls using abstractions of physical connections. These two quantities both c
 haracterize  aspects of performance but in different ways, and typically h
 ave been hard to relate to each other. We describe measurements on physica
 l testbed with fiber connections of lengths 0-75 kilometers. We obtain the
  normalized analytic capacity estimates using the transmissivity approxima
 tions derived using single photon coincidence measurements, and convert th
 em to bounds on throughput (measured in ebps) using a multiplier derived f
 rom co-located detector measurements. The results indicate consistent thro
 ughput measurements upper-bounded by their analytical capacity estimates a
 cross all connections.\n\nTag: Architecture, Data-Intensive, Network, Perf
