The article deals with the ongoing change in the architecture of metropolitan area networks, hard-pressed on one side by the deployment of 5G and new wireline systems and on the other side by the emerging of HW/SW disaggregation and cloudification paradigms.

A novel transmitter that offers both short-reach IM-DD transmission and higher optical budget coherent transmission is proposed for cost-effective user terminals. 25 Gb/s signal detection experiments confirm enhanced optical budget of 13 dB with high sensitivity of -37.7 dBm by modulation format switching.

We measured a seismic event with OFDR. OFDR together with the unique feature of adjusting the measurement performance was used to analyse the event from different perspectives, and it could also be useful for revealing the features of infrequent seismic events.

We extend our measurement-based model to accurately predict the gain of an EDFA for arbitrary input spectrum to the case of arbitrary pump currents with low root-mean square error and no extra training data and then, we analyze its accuracy against numerical simulations and experiments.

We propose a new metric called hubbedness to describe traffic flow in modern optical networks. We compare theoretical savings of point-to-multipoint vs point-to-point transceivers and find significant savings for a wide variety of traffic patterns when optical transceivers of sufficiently high data rates are available.
