“…5,14 We propose S-BVTs with a modular and scalable architecture based on a pay-as-you grow approach that can exploit multiple technology options such as direct modulation and external modulation with direct detection (DD) or coherent reception. 5,15 This flexible combination of the S-BVT building blocks enables to support multi-Tb/s transmission over the network, as demonstrated in. 16 A key element of the MB S-BVT is the MB optical aggregator/distributor that ideally consists of a programmable wavelength spectral switches (WSS), which can operate across multiple bands or either uses a combination of WSSs, each working at a certain band, together with combiners/splitters or other passive solutions.…”

Innovative multi band (MB) sliceable bandwidth/bitrate variable transceivers (S-BVTs) are proposed for future adoption in next-generation optical networks towards targeting the expected capacity scaling driven by the increasing traffic demand and emergence of new 6G services and applications with stringent requirements. To provide enhanced bandwidth/capacity and energy efficiency to support the envisioned growing demand, the use of MB technology is proposed and experimentally assessed up to 75 km of standard single mode fiber (SSMF) considering programmable MB S-BVTs. We demonstrate an aggregated capacity of 132.2 Gb/s exploiting S+Cbands and scalability towards enabling multi-Tb/s transmission within the metro/aggregation network segment. The sliceability of the MB S-BVT is demonstrated considering joint MB transmission (S+C) up to 2-hops network path of 75 km and an additional span of 50 km of SSMF for the C-band contribution. Different configurations based on single side band (SSB) and double side band (DSB) modulation and amplification technologies have been evaluated according to the particular scenario and band of operation. Finally, the programmability of the presented MB transceiver is also assessed as a key capability to promote network automation and flexibility. On this regard, a software-defined networking (SDN) agent based on open data model, such as OpenConfig, is implemented and validated to suitably reconfigure the transceiver according to the network requirements/demand. Key operational transceiver mode capabilities and configuration constraints, for the agent's implementation, are identified towards supporting MB transmission within future optical networks.

“…In this paper, we demonstrate the performance achievable with the PASSION network approach. In fact, this is an extension of a conference paper [9], where we deployed a five-node network path including HL4, HL3, and HL2 nodes featuring flexible spectral and spatial switching and covering up to a 110 km distance, including a 25 km 19-core multicore fiber (MCF). Here, we further describe essential hierarchical network design aspects leading to relevant savings in terms of number of transceivers at intermediate levels and provide a complete description of the S-BVTs used.…”

Disaggregation in optical networks is particularly relevant to be considered for the deployment of 5G services and towards the support of 6G. Particularly in the metro area network (MAN), this is especially crucial, as is the adoption of suitable photonic technologies enabling dense integration to design a sustainable network architecture. Furthermore, to dynamically allocate the ever-increasing traffic, supporting multiterabit capacity, an optimal usage of the available resources by properly exploiting the multiple dimensions (including the spectral and spatial ones), with programmable and adaptive data plane solutions, is key. In this work, we assess the capabilities of a disaggregated MAN that relies on new photonic devices, node architectures, and sliceable bandwidth/bit-rate-variable transceivers, approaching wavelength division multiplexing and space division multiplexing. A hierarchical network topology is attained and the feasibility of a cross-hierarchy optical continuum is demonstrated. In fact, we experimentally demonstrate the successful transmission of multiterabits/second capacity across multiple nodes corresponding to different hierarchy levels that have different implementation schemes and support different technologies. For the top tier hierarchy level nodes, we demonstrate the transmission of up to 8 × 11 = 88 spatial/spectral channels, for a total capacity of 1.676 Tb/s, employing a node architecture able to handle up to 2560 spatial/spectral channels at different aggregation levels and granularities.
