    Workshop: Enabling Space Division Multiplexing Technologies

 Space division multiplexing (SDM) exploiting spatial diversity to increase transmission capacity has been a hot research topic for photonics society over the past decade. From fiber innovation such as coupled-core fiber to petabit-per-second transmission over a single optical fiber, emerging SDM technologies start to make both academia and industry rethink about device design and system architecture.

 In this workshop, we discuss the enabling space division multiplexing technologies of fibers, amplification, devices, transmission and system.

    Workshop: Optical X-haul Networks – IEEE INGR optics

 As networks continue to grow in scale and performance, they face increasingly complex challenges and must constantly push the boundaries of technology to evolve. The IEEE International Network Generation Roadmap (INGR), a part of the IEEE Future Networks Initiative, was created to develop a 10-year roadmap for wireless networks. Recently, the INGR has been expanded to include optical networks, including x-haul networks such as fronthaul, mid-haul, and backhaul. X-haul networks are a critical component of the next generation mobile networks, forming the fabric of interconnections between radio units, distributed units, and central units.

 As the density of cells and the bandwidth offered by these cells increase, future X-haul networks will face increasingly stringent requirements for delay, bandwidth, energy efficiency, latency, synchronization, and deployment flexibility and scalability. To meet these demands, a variety of transport technologies, including dark fiber, WDM, gray optics, and TDM-PON, will be critical.

 This workshop will explore the current state, future challenges, and potential solutions of X-haul networks, including optical transceivers, transport, synchronization, PON with CO-DBA/CTI, and other relevant topics.

    Workshop: Role of Optical Technologies in the Future Datacenter Networks (DCNs)

The traditional datacenter networks (DCNs) based on all-electronic fat-tree architecture suffer from the issues of low capacity and scalability, long latency, and high power consumption. On the other hand, because all-optical technologies including optical transmission and switching have the advantages of high capacity, low power consumption, and better scalability, optical technologies are becoming more and more penetrating DCNs. Various electronic-optical hybrid architectures and even all-optical architectures have been proposed and studied. Testbeds and prototypes of these types of architectures have also been demonstrated by several important cloud service providers. A consensus seems to have been reached that optical technologies must and will be there in the future DCNs. 

This workshop aims at providing a platform for speakers and audience to discuss the challenges and solutions of optical technologies for DCNs. The topics will focus on several aspects: first, we will debate the necessity of optical technologies for DCNs; second, we will overview recent progress in short-reach optical transmission technology for DCNs; third, we will discuss all-optical switching technology and architectures for DCNs; fourth, we will discuss the control, management, and operation of optical-technology-enabled DCNs.

This workshop is expected to attract a strong industrial and academia audience as, in the current cloud-computing era, optical technologies for DCNs is becoming more interesting to service providers and network equipment vendors and what role the optical technologies will play in DCNs is still under extensive debate. 
This workshop will specifically discuss the following aspects:
1)    Is it necessary to bring optical technologies, especially optical switching, in DCNs?
2)    What role will optical technologies play in DCNs?
3)    When will optical technologies dominate DCNs?
4)    Which will be the main form in the future DCNs, electronic-optical hybrid or all-optical? For the hybrid type, what are the best percentages for electronic and optical technologies?
5)    Is it possible to have an architecture that can efficiently support both general data center traffic and special AI traffic? 
6)    Which switching type should be adopted for DCNs, packet switching or circuit switching? Which optical switching technologies will be employed for the future DCNs, and if so, which all-optical switching architecture will be, Torus or Clos?
7)    What values do DCN stakeholders expect milliseconds level optical switching to bring?
8)    Should we disaggregate the future DCNs, and if so, fully or partially?
9)    How to reduce service latency and power consumption of optical technology-enabled DCNs?
10)    How to improve scalability and reliability of optical technology-enabled DCNs?
