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.
Wavelength selective switch is becoming the central part of ROADM (reconfigurable optical add drop multiplexer). In a WSS, different wavelength channels from the input fiber can be independently switched to different output ports, as shown in the right side picture. The left side picture shows an actual WSS product from Finisar.
This illustration shows a generic design of WSS. This optical principle is used on many different WSS designs, such as LCoS or MEMS based WSS switches.
Multiple wavelengths come in from the input port. The input port is one port among the fiber array. The fiber array is in the direction of perpendicular to the screen, in other words, the fiber array is in and out of the screen, that is why you only see one port shown in the picture.
The light from the input port is first expanded and collimated by the collimation optics. Then the light is projected onto the dispersive element. In a LCoS based WSS, this dispersive element is a conventional grating. The purpose of the dispersive element is to spatially separate these multiple wavelengths. With a conventional grating, the wavelengths are separated into different angles. Blue to the top, green in the middle, and red to the bottom.
These lights are still collimated, so next they are focused by the focusing optics and projected onto the switching element. The purpose of the switching element is to direct different wavelengths to different output ports. In a LCoS based WSS, this switching element is a LCoS chip. This time, the switching element directs lights to different perpendicular angles, in other words, in the fiber array’s direction which is perpendicular to the screen. So when the lights trace back, they are focused into different output ports, depending on the switched angle by the switching element.

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.

This session will introduce the challenges and principles of designing high density WLANs. We'll present examples of VHD deployments in auditoriums or ballrooms, as the principles of deploying in these environments are applicable to any other high density coverage zone. Join us as we explore dimension and design for sites with adjacent auditoriums, best practices for estimating the number of user devices, and choosing between the three major RF coverage strategies.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

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.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
