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.

    Talking markets: Oclaro on 100 gigabits and beyond  

    Oclaro’s chief commercial officer, Adam Carter, discusses the 100-gigabit market, optical module trends, silicon photonics, and why this is a good time to be an optical component maker.

    Oclaro has started its first quarter 2017 fiscal results as it ended fiscal year 2016 with another record quarter. The company reported revenues of $136 million in the quarter ending in September, 8 percent sequential growth and the company's fifth consecutive quarter of 7 percent or greater revenue growth.

    Adam CarterA large part of Oclaro’s growth was due to strong demand for 100 gigabits across the company’s optical module and component portfolio.

    The company has been supplying 100-gigabit client-side optics using the CFP, CFP2 and CFP4 pluggable form factors for a while. “What we saw in June was the first real production ramp of our CFP2-ACO [coherent] module,” says Adam Carter, chief commercial officer at Oclaro. “We have transferred all that manufacturing over to Asia now.”

    QSFP28 MicroMux expands 10 & 40 Gig faceplate capacity

    • ADVA Optical Networking's MicroMux aggregates lower rate 10 and 40 gigabit client signals in a pluggable QSFP28 module
    • ADVA is also claiming an industry first in implementing the Open Optical Line System concept that is backed by Microsoft 

    The need for terabits of capacity to link Internet content providers’ mega-scale data centres has given rise to a new class of optical transport platform, known as data centre interconnect.

    Such platforms are designed to be power efficient, compact and support a variety of client-side signal rates spanning 10, 40 and 100 gigabit. But this poses a challenge for design engineers as the front panel of such platforms can only fit so many lower-rate client-side signals. This can lead to the aggregate data fed to the platform falling short of its full line-side transport capability.

    MultiPhy raises $17M to develop 100G serial interfaces

    Start-up MultiPhy has raised U.S. $17 million to develop 100-gigabit single-wavelength technology for the data centre. Semtech has announced it is one of the companies backing the Israeli fabless start-up, the rest coming from venture capitalists and at least one other company.

    MultiPhy is developing chips to support serial 100-gigabit-per-second transmission using 25-gigabit optical components. The design will enable short reach links within the data centre and up to 80km point-to-point links for data centre interconnect.

    “It is not the same chip [for the two applications] but the same technology core,” says Avi Shabtai, the CEO of MultiPhy. The funding will be used to bring products to market as well as expand the company’s marketing arm.

    ECOC 2015 Review - Final Part 

    The second and final part of the survey of developments at the ECOC 2015 show held recently in Valencia.  

    Part 2 - Client-side component and module developments   

    • The first SWDM Alliance module shown
    • More companies detail CWDM4, CLR4 and PSM4 mid-reach modules
    • 400 Gig datacom technologies showcased
    • The CFP8 MSA for 400 Gigabit Ethernet unveiled

    • Lumentum and Kaiam use silicon photonics for mid-reach modules
    • Finisar demonstrates a 10 km 25 Gig SFP28, and low-latency 25 Gig and 100 Gig SR4 interfaces 

     

    Shortwave wavelength-division multiplexing

    Finisar demonstrated the first 100 gigabit shortwave wavelength-division multiplexing (SWDM) module at ECOC. Dubbed the SWDM4, the 100 gigabit interface supports WDM over multi-mode fibre. Finisar showed a 40 version at OFC earlier this year. “This product [the SWDM4] provides the next step in that upgrade path,” says Rafik Ward, vice president of marketing at Finisar.

    ECOC '15 Reflections: Part 2 

    Part 2: More industry executives share the trends and highlights they noted at the recent European Conference on Optical Communication (ECOC) event, held in Valencia. 

     

    Martin Zirngibl, head of network enabling components and technologies at Bell Labs. 

    Silicon Photonics is seeming to gain traction, but traditional component suppliers are still betting on indium phosphide.

    There are many new start-ups in silicon photonics, most seem to be going after the 100 gigabit QSFP28 market. However, silicon photonics still needs a ubiquitous high-volume application for the foundry model to be sustainable.

    There is a battle between 4x25 Gig CWDM and 100 Gig PAM-4 56 gigabaud, with most people believing that 400 Gig PAM-4 or discrete multi-tone with 100 Gig per lambda will win.

     

    Will coherent make it into black and white applications - up to 80 km - or is there a role for a low-cost wavelength-division multiplexing (WDM) system with direct detection?

    Ciena's stackable platform for data centre interconnect  

    Ciena is the latest system vendor to unveil its optical transport platform for the burgeoning data centre interconnect market. Data centre operators require scalable platforms that can carry significant amounts of traffic to link sites over metro and long-haul distances, and are power efficient. 

    The Waveserver stackable interconnect system delivers 800 Gig traffic throughput in a 1 rack unit (1RU) form factor. The throughput comprises 400 Gigabit of client-side interfaces and 400 Gigabit coherent dense WDM transport.
