Infinera unveils its next-gen packet-optical platforms 

  • Infinera has announced its first major metro product upgrade since it acquired Transmode in 2015.
  • The XTM II platforms use CFP2-DCO pluggable modules for the line-side optics, not Infinera’s photonic integrated circuit (PIC) technology.
  • Infinera’s XTM II achieves new levels of power efficiency by adopting CFP2-DCO pluggables and a distributed switch architecture.

    Infinera has unveiled its latest metro products that support up to 200-gigabit wavelengths using CFP2-DCO pluggable modules.

    The XTM II platform family is designed to support growing metro traffic, low-latency services and the trend to move sophisticated equipment towards the network edge. Placing computing, storage and even switching near the network edge contrasts with the classical approach of backhauling traffic, sometimes deep within the network.

    Nokia’s PSE-2s delivers 400 gigabit on a wavelength

    Nokia has unveiled what it claims is the first commercially announced coherent transport system to deliver 400 gigabits of data on a single wavelength. Using multiple 400-gigabit wavelengths across the C-band, 35 terabits of data can be transmitted.

    Four hundred gigabit transmission over a single carrier is enabled using Nokia’s second-generation programmable Photonic Service Engine coherent processor, the PSE2, part of several upgrades to Nokia's flagship PSS 1830 family of packet-optical transport platforms.

    Kyle Hollasch“One thing that is clear is that performance will have a key role to play in optics for a long time to come, including distance, capacity per fiber, and density,” says Sterling Perrin, senior analyst at Heavy Reading.

    This limits the appeal of the so-called “white box” trend for many applications in optics, he says: “We will continue to see proprietary advances that boost performance in specific ways and which gain market traction with operators as a result”.

    Ciena shops for photonic technology for line-side edge  

    Briefing: DWDM developments

    Part 3: Acquisitions and silicon photonics

    Ciena is to acquire the high-speed photonics components division of Teraxion for $32 million. The deal includes 35 employees and Teraxion’s indium phosphide and silicon photonics technologies. The systems vendor is making the acquisition to benefit its coherent-based packet-optical transmission systems in metro and long-haul networks.


    Sterling Perrin

    “Historically Ciena has been a step ahead of others in introducing new coherent capabilities to the market,” says Ron Kline, principal analyst, intelligent networks at market research company, Ovum. “The technology is critical to own if they want to maintain their edge.”

    “Bringing in-house not everything, just piece parts, are becoming differentiators,” says Sterling Perrin, senior analyst at Heavy Reading.    

    Ciena designs its own WaveLogic coherent DSP-ASICs but buys its optical components. Having its own photonics design team with expertise in indium-phosphide and silicon photonics will allow Ciena to develop complete line-side systems, optimising the photonics and electronics to benefit system performance.

    Ericsson and Ciena collaborate on IP-over-WDM and SDN

    Do company partnerships work? Ericsson and Ciena certainly think so, and provide a compelling argument for their collaboration in the areas of IP-over-WDM and software-defined networking (SDN). More such partnerships should also be expected.


    Jan Häglund

    Ericsson and Ciena have signed a global strategic agreement that provides Ericsson with Ciena's optical networking technology, while Ciena benefits from Ericsson's broader service provider relationships.

    Packet optical transport: Hollowing the network core

    Intune Networks has developed an optical packet switching and transport (OPST) system that effectively turns fibre into a distributed switch.

    The platform enables a fully-meshed metropolitan networkIntune Networks' CEO, Tim Fritzley (right) and John Dunne, co-founder and CTO with software support for web-based services, claims the Irish start-up

    “What we have designed allows for the sharing of the same fibre switching assets across multiple services in the metro,” says Tim Fritzley, Intune’s CEO.

    The company is in talks with several operators about its OPST system, which is being used for a nationwide network in Ireland. The system is also part of an EC seventh framework project that includes Spanish operator Telefónica.
