Skyrocketing capacity demands and emerging 5G and industrial internet URLLC applications currently pose a new strict latency-oriented framework calling urgently for new radical architectural changes at the key aggregation infrastructure being in local proximity to the subscribers: the Central Offices (COs). A careful look into the CO reveals a capacity-latency predicament underlining the need for the employment of innovative technological solutions, with photonics emerging as the key enabling technology, that will establish a new NGCO ecosystem where component-level advancements can yield unparallel architectural benefits. OCTAPUS aims to deliver an agile, low-cost and energy-efficient PIC technology framework that will re-architect the NGCO ecosystem, transparently upgrading its capacity to 51.2Tb/s and beyond, through an innovative optically-switched backplane and transceiver toolkit. To realize its ambitious goals, OCTAPUS will leverage the novel integration of antimony-based Phase Change Materials (PCM) on the low-cost SiN to develop for the first time a non-volatile ns-scale optical switch technology for developing an ultra-high capacity optical backplane. OCTAPUS will also deploy a versatile portfolio of InP-based O-band optical components that will enable the realization of 50G low-power board-to-board and long-reach PON transceivers, securing 4x and 8x energy saving to existing state-of-the-art solutions, while reaching up to 37.5% cost improvement against conventional EML solutions, through its monolithic fabrication approach. Moreover, OCTAPUS will equip its novel PICs with low loss and compact interfaces to fibers, through advanced glass diplexer-embedded-interposers. Finally, OCTAPUS will synergize the developed optical components in a novel NGCO architecture, supporting 3 layers of traffic with deterministic latency guarantees for URLLC services, through the incorporation of reconfigurable express light paths along with TSN functionality.

飞速增长的容量需求以及新兴的5G和工业互联网URLLC应用目前提出了一个新的严格的面向延迟的框架，迫切需要在靠近用户的关键聚合基础设施（即中央办公室（CO））上进行新的根本性架构变革。对CO的仔细研究揭示了一个容量延迟困境，强调了采用创新技术解决方案的必要性，光子学成为关键的使能技术，这将建立一个新的NGCO生态系统，其中组件级的进步可以产生无与伦比的架构优势。OCTAPUS旨在提供一个灵活、低成本和节能的PIC技术框架，该框架将重新构建NGCO生态系统，通过创新的光交换背板和收发器工具包，将其容量透明地升级到51.2Tb/s及更高。为了实现其雄心勃勃的目标，OCTAPUS将利用锑基相变材料（PCM）在低成本SiN上的新型集成，首次开发非易失性ns级光开关技术，用于开发超高容量光背板。OCTAPUS还将部署基于InP的O波段光学元件的多功能产品组合，这将实现50 G低功率板对板和长距离PON收发器，通过其单片制造方法，确保现有最先进的解决方案节能4倍和8倍，同时与传统的EML解决方案相比，成本降低高达37.5%。此外，OCTAPUS将通过先进的玻璃双工器嵌入式插入器为其新型PIC配备低损耗和紧凑的光纤接口。最后，OCTAPUS将在新型NGCO架构中协同开发的光学组件，通过将可重新配置的快速光路沿着，支持3层流量，并为URLLC服务提供确定性延迟保证。
