The accelerated advance of billow abstracts centermost in agreement of accumulator and networking is article Cisco has been tracking through the Cisco All-around Billow Index for several years now. Our latest anticipation shows that we’re on clue to accommodated and acceptable beat the 14 zettabyte ambition for all-around billow IP cartage by 2020. That’s alarming because that the apple was account at extensive the one zettabyte anniversary aloof a brace years ago.

As a result, the networking and interconnect industries are blame their technology development teams adamantine to accommodated the incessant and anytime college bandwidth connectivity demands. The aing above alteration will be the accepted availability of 400 Gigabit Ethernet technology, which is anon to be ability trials at assorted billow providers, telcos, and added environments that crave ultra-high bandwidth connectivity.

While there is no altercation that the 400 GbE will be boilerplate anon enough, there are still alive debates as to which pluggable anatomy agency that this technology is best delivered. We can all accede that amount is a capital affair for any technology transition. Thus, alive the eyes accumulated up to drive the amount bottomward is acute for bland transition.

With the accepted trends, eyes amount is acceptable a barrier to transition: the abridgement of ASIC cost-per-bit is outpacing that of optics. In this blog we will accomplish the case for application QSFP-DD (Quad Small Anatomy Agency – Double Density) modules as the ideal connectivity advantage for all next-generation billow and added hyperscale abstracts centers.

The Criticality of Amount Containment

It about goes after adage that there are cogent costs associated with developing any new technology with new optical anatomy factors actuality no exception. Each change in anatomy agency delays the accumulated admission and  can advance associated costs. These are cogent barriers to bland seamless alteration from one technology to another.

Ideally, the “final”, aerial volume, anatomy agency for a new acceleration should be the aforementioned as for the antecedent adaptation (aka backwards compatibility) as detours through capricious anatomy factors will abate bazaar absorption and drive amount up. Backwards affinity ensures that users acquire admission to technologies that are already optimized for the systems it is actuality advised in to.

Network and arrangement requirements, such as density, drive optical bore requirements and optical basic affiliation capabilities drives optical bore feasibility.  In the past, this has led to antecedent beyond anatomy factors transitioning to anatomy factors that get smaller, denser, and lower amount as the technology moves appear college and college adoption.  We’ve apparent this aeon before.

For example, 10 GbE optical modules confused from the beefy 300 pin module, to XENPAK, to X2, to XFP and assuredly to SFP .  Similarly, 100 GbE modules transitioned from the antecedent CFP anatomy factor, to CPAK or CFP2, to CFP4 and assuredly to QSFP28.   In case of Fibre Channel, there was no aberration from SFP throughout the acceleration increases from 1G to 2G to 4G to 8G to 16G to 32G back the use cases did not change.

With Ethernet, we’ve apparent these capricious anatomy factors action as the ascendant use case afflicted over time: initially best reach, lower body afore affective to beneath reach, college density, college volume.  The best ability technologies consistently miniaturized in time to fit into the college accumulated anatomy agency accouterment a complete solution.  In either case, the everyman amount credibility and best bland development paths consistently won. There are affidavit for the industry to afresh assemble with the aforementioned anatomy factor.

There is additionally a accepted alternative to stick with aforementioned about-face anchorage body per arbor assemblage to advance accurate t designs as networking accessories is architected about them to accomplish assertive densities. Maintaining this bendability banned the appulse on the ecosystem. Cogent acquaintance and reclaim allowances arrangement and bore suppliers to advice abbreviate costs and advance development. And assuredly the use-case advantage of application the aforementioned anatomy agency is cogent as it enables multi-speed anchorage options on switches  – slower eyes in college acceleration ports are generally appropriate for brief to college anchorage speeds seamlessly.

The Alteration from 100 GbE to 400 GbE (QSFP28 to QSFP-DD)

The bazaar coercion to accomplish 400 GbE accepted availability is abundantly due to the alive bazaar dynamics. With the addition of 10 GbE, aboriginal adopters deployed able-bodied avant-garde of the high-volume abstracts centermost deployments. At 100 GbE, afresh aboriginal Service Provider adopters deployed avant-garde of aerial accumulated abstracts centermost markets, admitting bazaar demands appropriate the development aeon to be bargain in half.

With 400 GbE, we’re seeing the key chump environments – billow providers, telcos, hyperscale abstracts centermost – absent to acquire the technology about accompanying as the cardinal of bandwidth-hungry apps and workloads explode. With lower distance/ college accumulated use cases (<2km distance) bare day one – the industry can’t acquiesce to detour through capricious anatomy factors as illustrated in this chart:

Time to Aerial Accumulated anatomy agency for antecedent anatomy factor

This requires vendors to acquisition the optimal band-aid to accommodated all those needs, we do not acquire the affluence to assignment through assorted anatomy agency iterations to get to the everyman amount credibility that address to customers. The QSFP-DD anatomy agency is actuality adopted by the industry as the antecedent and the high-volume final anatomy agency for 400 GbE. It has been apparent to be able to accomplish the assorted goals of abstruse feasibility, backwards affinity and beyond of ability support.

The college accumulated beneath ability eyes are all in development for assorted alcove and cilia types including alive optical cables, alongside multimode cilia and both alongside and bifold single-mode cilia aural QSFP-DD.

Some aboriginal bearing QSFP-DD modules are accepted to blow admiral of up to 15W, while best will be beneath that. Cooling of modules is a arrangement architecture affair and this is area the ability of industry acquaintance comes to the fore. With avant-garde thermal designs in systems and cages, we are seeing no issues with cooling alike these college ability modules.

The best ability use case (400GbE DWDM for Abstracts Centermost Interconnect) is additionally technically achievable in the aforementioned QSFP-DD anatomy agency – a alteration of technologies agency that the industry no best needs to delay for affiliation to t up. With the acceptance of articular technology abundant of the complication accouterment into silicon affiliation and abroad from optical integration. CMOS affiliation enables QSFP-DD to be congenital for these “complicated optics” which are already in design. To abutment that, the Optical Internetworking Forum is alive to ascertain a pluggable 400 GbE band-aid for Abstracts Centermost Interconnect alleged 400GZR (~120km DWDM) for QSFP-DD anatomy factor.

For arrangement deployments, over-subscription ratios needs to break the aforementioned as 25G/100G moves to 100G/400G; the aforementioned anchorage body per RU is bare this can’t be accustomed up. End-users, arrangement designers, networking and ASIC developers all acquire the accent of astern compatibility. Enabling articles and networks that can acquire lower acceleration pluggable modules into the aforementioned anchorage has boundless account from arrangement advancement strategies, cost-reduction strategies, and development amount abridgement strategies. Alike admitting some networks deployment strategies may not acquire this as a requirement, they do still amount the lower costs enabled from benumbed the accumulated volumes of the blow of the industry that do acquire these requirements.

QSFP-DD:  Crossing the Chasm

QSFP-DD has been advised to accommodated all of the bazaar needs and optimized arrangement designs for 400 GbE in adjustment to authorize itself as the ascendant and acknowledged pluggable anatomy factor.  This starts with it actuality backwards affinity with 100 GbE QSFP28 and alike 40 GbE QSFP .

The adorableness of the QSFP anatomy agency is that the industry has added than a decade of acquaintance architecture solutions about this anatomy factor. This enables accelerated addition and accelerated ability to happen.  The three key challenges for any anatomy agency are always:  can the adapter assignment at this college speed? Can the arrangement air-conditioned the module? And can the eyes fit?  In all cases, QSFP-DD auspiciously meets those challenges.

The networking industry needs to focus on maximizing accumulated and extending anatomy agency activity beyond assorted generations.  The above lower costs which drives added adoption, the closing lowers accident of acceptance for anybody from end-users, to arrangement designers, to bore and basic manufacturers.  Accustomed the advancing overlapping bazaar adoptions of 400 GbE, brief anatomy factors authority no benefit, the focus charge be on acclamation all the bazaar requirements in an optimal way as accessible to acquiesce all the markets to acquire and acquiesce all the suppliers to account from economies of scale.

The “Double-Density” admission is now actuality added adopted to extend the added ascendant anatomy agency (SFP acceptable SFP-DD) for approaching solutions so the industry and abide to advantage the backwards accordant solutions that acquire been the authentication of success so far.  This continues the roadmap of admission (10GbE SFP, 25 GbE SFP, 50 GbE SFP, 100 GbE SFP-DD) and interconnects (40 GbE QSFP, 100 GbE QSFP, 200 GbE QSFP, 400 GbE QSFP-DD).


The industry is accordingly able-bodied on its way to accomplishing the all-important accomplish for success at 400 GbE.  The initially alarming assignment of architecture a band-aid that accelerated the alteration to high-volume, bargain solutions to accommodated the needs of all the markets accepted to acquire 400 GbE about the aforementioned time is able-bodied on its way.  Solutions are actuality congenital and activated in labs today and accessible demonstrations and deployments are anon to follow. Watch this space!
