Packet-optical Add/Drop multiplexer technology: A pragmatic way to introduce optical packet switching in the next generation of metro networks
This paper describes a packet-optical add/drop multiplexer technology designed for Metro-ring networks to reduce cost and power consumption with a network efficiency comparable to a full-electronic Ethernet solution. A demonstrator including three nodes is shown.
Photonic integrated WDM cross-connects for optical metro and data center networks
We present a scalable and novel modular optical metro core node architecture and low cost metro access node architectures with edge computing functionalities employing photonic WDM integrated switches. Photonic integrated switches has been des igned as the building blocks to realize the modular metro node architectures, namely photonic WDM switches with express and add/drop ports, photonic integrated WSS aggregation/disaggregation functions for merging/dropping the network traffic, and photonic integrated multi-cast switch (MCS), as well as bandwidth variable transceivers aggregators to achieve multi-Terabits/second operation. Moreover, a dynamic re-configurable metro-access nodes based on low-cost 2-degree photonic integrated mini-ROADMs will be discussed. The lossless photonic WDM switches are based on InP technology and employ semiconductor optical amplifiers as on -chip gain element and fast switch. The photonic WDM circuits allows to switch multiple format data signals in wavelength, space, and time for full flexibility, scalability of the interconnected network elements as well as capacity. Applications to data center interconnects and 5G will be discussed and experimental results reported.
Implementation of ultrafast widely-tunable burst-mode 10 Gbit/s transceiver
A tunable 10 Gbit/s transceiver, 300-pin MSA compatible, for optical burst-switching applications, is presented. Fast tuning (<50 ns) between 80 channels over the entire C-band together with a fast locking (<100 ns) burst-mode receiver are demonstrated.
