Ciena to sell its own coherent modules

The systems vendor is expanding its offerings to include WaveLogic modem chips and coherent optical modules.

Ciena is developing its own coherent modules to sell to the telecom and datacom markets. 

The system vendor has set up the Optical Microsystems Division business unit to promote its WaveLogic coherent modem technology to the marketplace. Until now it has licensed its WaveLogic Ai digital signal processor (DSP) to module makers Lumentum, NeoPhotonics and Oclaro. But now it is planning to sell its own coherent modules.

In a job advert for a head of sales channel development, Ciena says the Optical Microsystems Division's goal is ‘to develop and productize electro-optic components and modules for sale to global systems integrator customers to be incorporated in their products for sale to telecom and data network customers’.

And at the recent European Conference on Optical Communication (ECOC) held in Rome, a network equipment manufacturer said it was approached by Ciena enquiring if it was interested in buying coherent modules from the company.

Ciena picks ONAP’s policy code to enhance Blue Planet  

Ciena is adding policy software from the Linux Foundation’s open-source Open Network Automation Platform (ONAP) to its Blue Planet network management platform.

Operators want to use automation to help tackle the growing complexity and cost of operating their networks.

Kevin Wade“Policy plays a key role in this goal by enabling the creation and administration of rules that automatically modify the network’s behaviour,” says Kevin Wade, senior director of solutions, Ciena’s Blue Planet. 

Incorporating ONAP code to enhance Blue Planet’s policy engine also advances Ciena’s own vision of the adaptive network.

Verizon, Ciena and Juniper trial 400 Gigabit Ethernet 

Verizon has sent a 400 Gigabit Ethernet signal over its network, carried using a 400-gigabit optical wavelength.

The trial’s goal was to demonstrate multi-vendor interoperability and in particular the interoperability of standardised 400 Gigabit Ethernet (GbE) client signals.

Glenn Wellbrock“[400GbE] Interoperability with the client side has been the long pole in the tent - and continues to be,” says Glenn Wellbrock, director, optical transport network - architecture, design and planning at Verizon. “This was trial equipment, not generally-available equipment.” 

It is only the emergence of standardised modules - in this case, an IEEE 400GbE client-side interface specification - that allows multi-vendor interoperability, he says.

Has coherent optical transmission run its course?

Feature: Coherent's future

Three optical systems vendors share their thoughts about coherent technology and the scope for further improvement as they look two generations ahead to symbol rates approaching 100 gigabaud   

Optical transmission using coherent detection has made huge strides in the last decade. The latest coherent technology with transmitter-based digital signal processing delivers 25x the capacity-reach of 10-gigabit wavelengths using direct-detection, according to Infinera.

Since early 2016, the optical systems vendors Infinera, Ciena and Nokia have all announced new coherent digital signal processor (DSP) designs. Each new generation of coherent DSP improves the capacity that can be transmitted over an optical link. But given the effectiveness of the latest coherent systems, has most of the benefits already been achieved?

“It is getting harder and harder,” admits Kim Roberts, vice president, WaveLogic science at Ciena. “Unlike 10 years ago, there are no factors of 10 available for improvement.”

Real-time visibility makes optical networking smarter

Part 1: Ciena's Liquid Spectrum

Systems vendors are making optical networks smarter. Their latest equipment, combining intelligent silicon and software hooks, can measure the status of the network and enable dynamic network management.

Ciena recently announced its Liquid Spectrum networking product while Infinera has launched its Instant Network. Both vendors exploit the capabilities of their latest generation coherent DSPs to allow greater network automation and efficiency. The vendors even talk about their products being an important step towards autonomous or cognitive networks.

Books of the year 2016 - Part 2

More industry figures comment on books read this year. Here are Finisar's Simon Poole's and Ciena's Loudon Blair's recommendations.

Simon Poole, director, new business ventures, Finisar Australia

The highlight of the year in fiction was reading The Shepherds’ Crown, the last of the Discworld novels from the wonderful Terry Pratchett. He, along with his cast of extraordinary characters, including the marvellous Tiffany Aching – a fabulous role model for teenage girls, held up a mirror to the foibles and strengths of our humanity, and will be sorely missed.

Ciena brings data analytics to optical networking 

  • Ciena's WaveLogic Ai coherent DSP-ASIC makes real-time measurements, enabling operators to analyse and adapt their networks.     
  • The DSP-ASIC supports 100-gigabit to 400-gigabit wavelengths in 50-gigabit increments. 
  • The WaveLogic Ai will be used in Ciena’s systems from 2Q 2017.  

Ciena has unveiled its latest generation coherent DSP-ASIC. The device, dubbed WaveLogic Ai, follows Ciena’s WaveLogic 3 family of coherent chips which was first announced in 2012. The Ai naming scheme reflects the company's belief that its latest chipset represents a significant advancement in coherent DSP-ASIC functionality.  

Helen XenosThe WaveLogic Ai is Ciena's first DSP-ASIC to support two baud rates, 35 gigabaud for fixed-grid optical networks and 56 gigabaud for flexible-grid ones. The design also uses advanced modulation schemes to optimise the data transmission over a given link.

Perhaps the most significant development, however, is the real-time network monitoring offered by the coherent DSP-ASIC. The data will allow operators to fine-tune transmissions to adapt to changing networking conditions.
