Following a short update on the latest developments for unrepeatered subsea cable systems (150 x 100G on 410 km, 100G on 607 km), this presentation describes the genesis and the development of the industry’s most advanced subsea repeaters, with innovative electrical, optical and mechanical designs. This Raman-based repeaters was deployed by Xtera in May 2015, an industry’s first. This presentation was delivered at WDM & Next Generation Optical Networking EMEA 2015 conference (22-25 June 2015 – Nice, France).

Why Direct Transmission of 5G Radio over Optical Fiber?Bob Walter
An argument for replacing CPRI in mobile wireless fronthaul links with high performance analog optical transceivers that directly transmit high order modulation, spread spectrum OFDM radio signals over optical fiber and meet 3GPP E-UTRA specs. Replacing CPRI with an RF over Fiber link enables the consolidation of the radio and the virtualization of the remote radio head (RRH) within the baseband unit (BBU). In turn, this can reduce the network complexity, power consumption, CAPEX and OPEX while increasing bandwidth and improving bandwidth efficiency. If BBU processing time could be reduced to less than 2.3 ms, fronthaul reach could be extended up to 70 km.
Implications of super channels on CDC ROADM architecturesAnuj Malik
OFC 2014 Presentation
This study proposes CDC ROADM architecture compatible with emerging DWDM super-channel technology. A real world network model is used to quantify that this architecture requires fewer network components leading to less capital and operational costs.
At a time when new network topologies are developed due to the advent of new operators or users of long-haul optical transmission infrastructure, longer spans and longer all-optical data paths are becoming critical capabilities. This presentation details how advanced optical Raman amplification enables these new network designs and ultra-long-haul transmission of 16QAM/200G carriers as well.

Real-Time 200Gbit/s PAM4 Transmission Over 80km SSMF Using Quantum-Dot Laser ...ADVA
Using 200Gbit/s four-channel transmitter and receiver optical subassemblies (TOSAs/ROSAs) combining quantum dot laser and silicon photonics technology from Ranovus, ADVA Optical Networking demonstrated how to build cost-effective 400Gbit/s transponder cards at OFC 2017.
Introducing Coherent 100ZR for the optical edgeADVA
Our Coherent 100ZR empowers service providers to easily and affordably deploy 100Gbit/s coherent transceiver technology in the access network. Purpose-built for the optical edge, it features the industry's first DSP to meet 5W QSFP specifications and is offered in both C-temp and I-temp variations for a broad range of deployment options.
Stephan Rettenberger’s presentation at NGON & DCI World explained how coherent technologies can help to create a future-proof network and examined the role that direct detect optics play at the edge.
The session begins with an overview on the basic impairments in a fiber based optical network. It will then cover what technologies are available to alleviate these linear and non-linear impairments. The fundamental components of DWDM (ie filters, optical amplifiers, lasers, & receivers) will also be covered. The basic design principles that go into designing DWDM networks will be discussed. Converged platforms based on OTN infrastructures have been introduced into the transport network recently and this will be covered. Lastly, innovations in DWDM transport such as 200G transmission, Flex Spectrum ROADM and control plane integration will be summarized.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images
