Hyperscaler or ICP? 

Several terms are commonly used when referring to leading internet companies, those that operate large-scale data centres and typically are household names.

Terms used include internet content providers (ICP), hyperscalers and mega data centre operators. Meanwhile, a leading system vendor, in a briefing, referred to ‘global content providers’.  

The terms are used interchangeably but, not surprisingly, there are differences.

Features added around 400ZR aims to bring order to 400ZR+

The OIF has started a project to combine Flexible Ethernet (FlexE) technology with the 400ZR coherent interface standard.

Karl Gass400ZR is designed to transmit a 400 Gigabit Ethernet (GbE) signal over at least 80km using coherent optical transmission.

Adding FlexE technology will enable 4x100GbE signals to also be transmitted.

Separately, the OIF has started a project to create a 96 gigabaud (GBd) coherent driver modulator specification. Such a symbol rate enables 800 gigabits of data to be sent using a single carrier.

ECI Telecom details its cell-site gateway for 5G

ECI Telecom has unveiled its cell-site router for 5G that also supports existing 3G and 4G wireless standards. 

You need to support the existing one or two generations of cellular networks,” says Jimmy Mizrahi, ECIs executive vice president and head of global portfolio.

Jimmy MizrahiThe platform, the NPT 1022 cell-site router, is the first of several platforms that ECI will launch for 5G as it upgrades and expands its Neptune product line.

The 1022 is part of a new line of products covering all layers of the network, starting at the cell site and going to aggregation and the metro core,” says Ezra Yehezkel, product line manager, packet transport solutions at ECI.

The Neptune portfolio will include a high-capacity packet-processing platform that can scale to 16 terabits.

Infinera prepares for first ICE6 coherent DSP samples

Infinera has taped out its 7nm CMOS FlexCoherent 6 digital signal processor (DSP) and expects samples of the coherent chip in the next fortnight.

“We are ready to start fabricating prototype modules,” says Robert Shore, senior vice president of marketing at Infinera (pictured).

The DSP, along with Infinera’s photonic integrated circuit (PIC) that was demonstrated at the OFC show held in March, will be integrated into a module that supports two wavelengths, each capable of supporting up to 800 gigabits of data. 

The company expects to have a prototype of the 1.6-terabit Infinite Coherent Engine 6 (ICE6) module by year-end, while the first ICE6-based products are scheduled for the second half of 2020.

It is early morning and the air is cool. I'm seated outside at a coffee bar in Herzliya’s marina awaiting Jörg-Peter Elbers, senior vice president, advanced technology, who is in Israel visiting local ADVA staff.   

He arrives as the bar opens and we are the only customers.

Just as we are about to start, the waitress informs us that the barista has yet to arrive. Breakfast can be ordered but we must wait for coffee.

Cisco-Acacia blurs the optical ecosystem vendor divide  

Cisco Systems’ acquisition of Acacia Communications would make it first to market with a 400ZR pluggable coherent interface. So claims Vladimir Kozlov, CEO of LightCounting Market Research. 

“This is the main reason Cisco is doing the deal,” says Kozlov. “It is very important for Cisco to get its core routers with DWDM optics and push network evolution in this direction.” 

Cisco is keen to grow its market share among service providers and lead in the development of software for automating telecom networks centred around routers, he says: “This will be the best way for Cisco to re-energise its optical transport business.”

Tom Williams, Acacia“We are planning to sample [the 400ZR] before the deal closes,” says Tom Williams, vice president for marketing at Acacia. “Our plan is to be first to volume, that is the most important thing.”

The acquisition is expected to be completed in the second half of Cisco’s fiscal year, 2020 (February-July 2020).

WaveLogic 5: Packing a suitcase of ideas into 7nm CMOS  

  • Ciena’s WaveLogic 5 coherent digital signal processor family comprises the Extreme and Nano chips
  • The WaveLogic 5 Extreme maximises optical capacity and transmission reach while the Nano is targeted at compact, power-conservative applications

Advancing coherent optical transmission performance to benefit its platforms; targeting the emerging coherent pluggable market opportunity; selling modules directly, and being more vertically integrated. All these aspects were outlined by Cisco to explain its intention to buy the coherent optical transmission specialist, Acacia Communications; a deal set to be completed in the spring of 2020.      

But this also fits the strategy being pursued by Ciena with its next-generation WaveLogic 5 family of coherent DSPs.

 

Kim Roberts

The WaveLogic 5 continues Ciena’s tradition of issuing a coherent digital signal processor (DSP) family approximately every three years: Ciena announced the WaveLogic 3 in 2012 and the WaveLogic Ai in 2016

Ciena has managed to maintain its three-yearly cadence despite the increasing sophistication of each generation of coherent DSP. For example, the WaveLogic 5 Extreme will support 800 gigabits-per-wavelength, double Ciena’s WaveLogic Ai that has been shipping for nearly two years.
