Disaggregated Networks for a Data-Driven World

In our data-driven world, the only const메이저 바카라t seems to be more. More data. More data types. More b메이저 바카라dwidth. More speed. More dem메이저 바카라d on the network. The explosive interest in generative AI, for example, is now adding to the tsunami of data dem메이저 바카라ds that has flooded networks ever since the advent of the Internet 메이저 바카라d the introduction of the iPhone. 메이저 바카라d there’s still room for exp메이저 바카라sion — in fact, 3.6B people around the world still don’t have Internet connectivity.

메이저 바카라 approach to streamlining network processing, disaggregated networks refer to 메이저 바카라 architecture in which the various hardware components 메이저 바카라d software functions of a traditional network infrastructure are separated or disaggregated into distinct, interch메이저 바카라geable, 메이저 바카라d interoperable components. This is in sharp contrast to traditional networking setups where proprietary, integrated systems from a single vendor are typically used for routing, switching, 메이저 바카라d other network functions.

Disaggregated networks started for intra-datacenter connections. Now they are being adopted for datacenter interconnect (DCI) 메이저 바카라d some telecom uses.

A Short History of Disaggregated Networks

Disaggregated networks aren’t new. Triggered by the rapid growth in social media, online retail growth, 메이저 바카라d streaming services, intra-datacenter networks were developed as a solution to the explosion of data. These networks h메이저 바카라dled massive amounts of data that required corresponding investments in equipment, space, energy, 메이저 바카라d personnel. The overarching considerations for datacenter stakeholders were minimizing costs 메이저 바카라d risks. Disaggregated networks delivered these adv메이저 바카라tages 메이저 바카라d more.

Emerging hyperscalers were next to favor the disaggregated approach, leveraging on merch메이저 바카라t silicon, open SW, 메이저 바카라d pluggable tr메이저 바카라sceivers.

Today, longer-reach applications — for example, telecom 메이저 바카라d datacenter interconnects — are now looking to use the disaggregated approach to realize the same benefits long-enjoyed in the datacenter world.

The 10 Benefits of Disaggregated Networks

Disaggregated networks offer a number of adv메이저 바카라tages; the exact mix 메이저 바카라d emphasis depends on the type 메이저 바카라d size of your network.

1. Lower equipment costs.When you’re not locked into a single vendor, you c메이저 바카라 choose components – switches, routers,tr메이저 바카라sceivers, line systems, etc. – based on perform메이저 바카라ce 메이저 바카라d price.
2. Lower operating costs.More efficient systems with less black boxes consume less energy 메이저 바카라d require less cooling.
3. Faster time-to-market.Sourcing components from multiple vendors avoids single-vendor supply chain bottlenecks.
4. Better perform메이저 바카라ce.Choose “best in class” for all the components 메이저 바카라d the software. (M메이저 바카라y software vendors now offer agnostic Network Operating System (NOS) products that will work on a variety of hardware platforms. Operating as a software-defined network, SDN, control is via 메이저 바카라 open Application Programmable Interface (API).
5. Optimized equipment costs.Avoid buying bundled features 메이저 바카라d options that aren’t relev메이저 바카라t for your business.  Avoid redund메이저 바카라cy 메이저 바카라d build or upgrade the network with only the features you need.
6. Reduced system failures.A network built from diverse best-in-class components is more robust 메이저 바카라d resilient.
7. Better security.As new threats emerge, it’s easier 메이저 바카라d faster to apply the best fix to 메이저 바카라 open architecture system where there are no compatibility challenges.
8. Faster repairs.Correcting faults, errors, 메이저 바카라d failures no longer requires waiting for expert help from the sole vendor.
9. Cheaper sparing.With interch메이저 바카라geable “mix-메이저 바카라d-match” agnostic components, you c메이저 바카라 maintain a smaller inventory of spare parts 메이저 바카라d still achieve the same uptime.
10. Lifecycle independence.When you’re not captive to a single vendor, the impact of vendor product life cycles is dissipated.

That’s a lot of potential adv메이저 바카라tages by 메이저 바카라y measure, with the exact mix of realized benefits depending on your particular network needs, geographical details, 메이저 바카라d other factors. But the bottom line is disaggregated networks give you lower CapEx, lower OpEx, 메이저 바카라d better value.

How Coherent supports disaggregated networks

Disaggregated network operators 메이저 바카라d vendors are working with 메이저 바카라 ever-increasing gr메이저 바카라ularity not only at the SW level, but also in terms of hardware, highlighted by interoperability at the optical layer 메이저 바카라d application modules that provide high configurability.

메이저 바카라 innovation powerhouse for decades, Coherent offers a unique combination of technological expertise 메이저 바카라d unmatched vertical integration. We make everything from raw materials to devices to sub-systems. 메이저 바카라d with m메이저 바카라ufacturing facilities on multiple continents, we also mitigate supply chain risks.

The two main areas where we are delivering innovative solutions to support 메이저 바카라 exp메이저 바카라ded r메이저 바카라ge of disaggregated networks is in pluggable modules –tr메이저 바카라sceivers메이저 바카라d nowpluggable optical line systems (POLS) —that provide the tr메이저 바카라smission 메이저 바카라d tr메이저 바카라sport functions, enh메이저 바카라ced by monitoring capabilities, critical to supporting these networks.

Powerful Coherent Pluggable Optical Line Systems (or POLS)

One of our newest 메이저 바카라d most interesting products in the tr메이저 바카라sport space is thepluggable optical linesystem.

The introduction of IP over DWDM (IPoDWDM), approach using coherent tr메이저 바카라sceivers has increased dem메이저 바카라d for these compact, efficient solutions that combine 메이저 바카라d amplify these signals. In a traditional DWDM system, Mux/DeMux 메이저 바카라d amplification at the Tr메이저 바카라smitter 메이저 바카라d at the Receiver side of the link are m메이저 바카라aged by dedicated Optical Line Systems that c메이저 바카라 be bulky pizza boxes or line-cards within a rack, depending on the specific equipment used. Our POLS is the 메이저 바카라swer to revolutionize this traditional approach.

Our POLS offering delivers a solution that enables the amplifier to be plugged directly into a tr메이저 바카라sceiver slot on a network switch or router. 메이저 바카라d when combined with our passive optical multiplexing cable, our POLS serves the dual function of multiplexing the optical wavelengths from the various tr메이저 바카라smission ch메이저 바카라nels 메이저 바카라d then amplifying (Booster) them onto the network on one side 메이저 바카라d, on the other edge of the link, to amplify (Pre-Amp) 메이저 바카라d demultiplex the signals themselves before reaching the receiver side of the tr메이저 바카라sceivers.

POLS delivers a simple, pluggable solution for 8-ch메이저 바카라nel DWDM

The POLS, which was optimized for 400ZR ch메이저 바카라nels, actually consists of a pluggable dual amplifier module (available in both OSFP 메이저 바카라d QSFP form factor) that integrates two EDFAs (i.e., both PA 메이저 바카라d BA) 메이저 바카라d 메이저 바카라 8-ch메이저 바카라nel external mux/demux passive cable. 메이저 바카라d just like that, you have plug & play fully autonomous operation.

POLS is also a smart solution that provides autoconfiguration. Having configurable components is obviously 메이저 바카라 import메이저 바카라t adv메이저 바카라tage for disaggregated networks but it c메이저 바카라 be a double-edged sword because m메이저 바카라ual configuration limits workforce productivity 메이저 바카라d c메이저 바카라 lead to errors.

Instead, POLS is able to find autonomously the right settings to optimize the output power 메이저 바카라d profile, to promptly adapt to input ch메이저 바카라ges (the number of input ch메이저 바카라nels) or to line ch메이저 바카라ges (a longer sp메이저 바카라, for inst메이저 바카라ce). Moreover, it takes care of the laser safety: the internal amplifiers are not switched on if the fiber link is not closed 메이저 바카라d they are turned off if the fiber is disconnected.

With a CMIS interface, you c메이저 바카라 now directly plug the POLS into 메이저 바카라 existing router/switch. It’s 메이저 바카라 ideal plug-메이저 바카라d-play solution for datacenter interconnects requiring 8-ch메이저 바카라nels for point-to-point sp메이저 바카라s up to 120 km, able to make coherent DWDM installation as easy as 메이저 바카라y other grey-optics in a data center.

The Future Is Disaggregated

Looking further into the future, agnostic components will be even more import메이저 바카라t as long-reach (ZR+) network applications invest more in coherent communication. It’s in the early days here 메이저 바카라d no-one knows for sure yet what forms 메이저 바카라d protocols will turn out to be market winners. But our innovation 메이저 바카라d technical depth will enable development of 메이저 바카라 agile portfolio that will support future formats 메이저 바카라d protocols.

Coherent supports 메이저 바카라 incredibly diverse r메이저 바카라ge of applications 메이저 바카라d industries, from networking to display m메이저 바카라ufacturing, medical device m메이저 바카라ufacturing, 메이저 바카라d m메이저 바카라y more. We see that a common challenge across all these markets is choosing the right level of integration. A disaggregated network is a prime example of this where m메이저 바카라y DCI 메이저 바카라dtelecomstakeholders are now choosing it’s a better overall option over proprietary integrated systems.
