<li>Abstract: Reconﬁgurable optical add/drop multiplexers (ROADMs) are able to provide ﬂexible wavelength path provisioning in wavelength division multiplexing (WDM) networks. However, the capability of conventional ROADMs is limited to handling wavelength paths, and it does not support ﬁnezgranularity in add/drop multiplexing of packets. Recently, we have proposed and demonstrated a packet-selective ROADM that combines an acoustooptic wavelength-tunable ﬁlter (AOTF) and an optical packet ADM (PADM) using optical code label processing.  It provides more efﬁcient utilization of wavelengths than conventional ROADMs. However, the bit rate of the demonstration was limited up to 10 Gbit/s. In this paper, we newly develop a label-selectivity-enhanced optical en/decoder, which allows the optical label recognition with 40-Gbit/s nonreturn-to-zero (NRZ) data packets, and a wide pass-band AOTF for 40-Gbit/s signals.  Furthermore, we develop 640-Gbit/s throughput, packet-selective ROADM prototype, and demonstrate a ﬁeld trial of granularity-ﬂexible 3-node optical network over 173 km. Error-free packet ADMs (error rate of under) for all 16-wavelength channels at all nodes are obtained.
