Ribbon offers for trial its 1.2T wavelength 9408 platform

Ribbon Communications has started working with operators to trial its latest Apollo 9408 optical transport platform that supports 1.2 terabits per second (Tbps) optical wavelengths.

The company's modular platform also can send 800 gigabit-per-second (Gbps) wavelengths over 1,000km and 400Gbps wavelengths over ultra-long-haul networks.

"We have conducted trials, including one with a Tier 1 European provider," says Jonathan Homa, senior director of solutions marketing at Ribbon. "You can get 1.2 terabits within major cities, 800 gigabits covering major states or regions, and 400 gigabits for about as long as you want to go."

"The Apollo 9408 is Ribbon's first disaggregated transponder unit or compact modular box using the CIM 8 for up to 1.2Tbps of wavelength speed," says Jimmy Yu, vice president at market research firm Dell'Oro Group.

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.
