coherent M&A starts....

coehernt DSP leadersip is worth at least $2.6 billion in Cisco dollars.

more to come?

Re: Huawei OptiXtreme oDSP This article is so biased it looks like sponsored by Infinera, at a time their shares are going down the sink. Not saying it's sponsored, just saying it looks sponsored (written by an Infinera Exec for 16 years and who probably still keeps stong ties), it feels sponsored (the verbage is identical to Infinera's Marketing department), and it tastes sponsored (makes Infinera look great at a time all other indicators make it look otherwise).

Having said that, it's true that DSP is central to Optical Networking, but like many other things. So this article is not enough of a smoke screen to cover for the very worrying trend in INFN's share price. INFN should focus less on Marketing and more on soul searching.

Re: Huawei towncalendars OptiXtreme printable calendar oDSP All the 3 letter acronyms sounds great, what exactly is the osnr performance of the Huawei device/module? 

0.1W/G on the DSP doesn't sound that great either. Wasn't Acacia claiming CFP2-DCO 200G at 20W for the whole module??

That CMS stuff looks like it's made to accommodate old line system that cannot recognize nyquist lambdas

Re: Huawei OptiXtreme oDSP SeniorR&57845 -- Thanks for the interest, but this is not a sponsored column.

Serge used to work at Infinera, but doesn't any longer, so he has detailed knowledge of that company.

Re: Huawei OptiXtreme oDSP I think it's important to mention that the author of the article is actually employed by Infinera. Which explains why there is a pitch on Infinera's PIC in an article on DSP and also why Infinera is put in a positive light of having a DSP, whereas they might as well just be buying the 600G DSP from the two available merchant sources in the market.

So I suggest that Light Reading explicitely states that this article is not written by an independent analyst, but is in fact sponsored by Infinera.

Re: Huawei OptiXtreme oDSP Serge,

Have you seen any other DSP vendor refering to "Channel-matched shaping (CMS)" and "Optical-Layer AI Neurons" and to "high-performance oDSP" and "new-generation power efficient oDSP"?

As james0075 indicated - "According to OVUM's data, Huawei has shipped over 127k 100G/200G ports in year 2017, which is more than Ciena+Nokia+Infinera(118K in total)." - Huawei is well positioned concerning the following consideration in your article:
"Given that the R&D investment required for a new DSP now runs to several tens of million dollars, the financial viability of an in-house DSP capability is heavily leveraged on maximizing volumes, and favors large and/or rapidly growing suppliers that can achieve the revenue and profitability required to fund this operational expense.".

When you follow Huawei activities in ITU-T SG15 and OIF, then you can see that Huawei is pushing very hard to get standardized 100G, 200G and 400G FlexO coherent interfaces for 80km (metro-edge, metro-aggregation) and 450km (metro-core), using Staircase FEC for 100G and CFEC/CFEC+ for 200G/400G FlexO interfaces. These FlexO interfaces can also be grouped to support PHY bonding and wavelength bonding, so that larger OTN OTUCn signals can be transported; e.g. 1T OTUC10 carried via five 200G FlexO coherent PHYs/wavelengths. G.709.3 (frame format, FEC) and G.698.2 (optical parameters) are the associated standards.

These 100G, 200G, 400G FlexO coherent interfaces are intended to become available in QSFP-DD-DCO/OSFP-DCO type module for 80km version and CFP2-DCO module for 450km.

These FlexO coherent modules are likely to support on their system side (electrical interfaces) OTN (FOIC, G.Sup58) and Ethernet (AUI, 802.3) protocols. Ethernet signals will be mapped into FlexO (with or without intermediate OTN functionality). Such FlexO coherent modules can be plugged into line cards in OTN equipment and in PKT switch equipment. This dual deployment is critical to prevent DSP R&D investment going through the roof.

I will address these developments in one of the panel sessions in ECOC on Sunday afternoon.

Re: Huawei OptiXtreme Smartcric on web site oDSP The information contained within the links you sent references 600G/wave, 16nm finFET and 40T fiber capacity; these specs all happen to also correspond to those for the Acacia AC1200 DSP that is currently being introduced to the market.

Re: Huawei OptiXtreme oDSP According to OVUM's data, Huawei has shipped over 127k 100G/200G ports in year 2017, which is more than Ciena+Nokia+Infinera(118K in total).

If Huawei is buying from any supplier on the market, they must be SUPER RICH now. I don't think Acacia or any supplier on market would have this kind of capacity. 

But you are right, if you consider Hisilicon as an "external" DSP supplier to Huawei.

Re: Huawei OptiXtreme oDSP thank you for posting those links; very useful and on-topic info.

what remains unclear is whether the Huawei oDSP was developed *in-house* (ie:  Huawei engineers coded the DSP algorithm, designed the ADC/DAC, did the chip layout, etc), or whether Huawei's DSP capability was implemented using an externally-sourced part from a DSP vendor.

The information contained within the links you sent references 600G/wave, 16nm finFET and 40T fiber capacity; these specs all happen to also correspond to those for the Acacia AC1200 DSP that is currently being introduced to market.  

So it is also feasible (and IMO likely) that Huawei's oDSP feature is enabled through an external DSP supplier.  Happy to hear if you have more info on any in-house DSP development work at Huawei?
