Elenion's coherent and fibre-to-the-server plans

  • Elenion’s coherent chip - an integrated modulator-receiver assembly - is now generally available. 
  • The company has a silicon photonics design library that includes over 1,000 elements. 
  • Elenion is also developing an optical engine for client-side interfaces.

Elenion Technologies has given an update on its activities and strategy after announcing itself eight months ago. The silicon photonics-based specialist is backed by private equity firm, Marlin Equity Partners, which also owns systems vendor, Coriant. Elenion had already been active for two and a half years and shipping product when it emerged from its state of secrecy last December

Larry SchwerinElenion has since announced it is selling its telecom product, a coherent transceiver PIC, to Coriant and now other companies.

It has also progressed its optical engine design for the data centre that will soon be a product. Elenion has been working with Ethernet switch chip maker, Cavium, and data centre player, Microsoft, as part of its datacom work.

“We have moved forward,” says Larry Schwerin, the CEO of Elenion.

Coherent optics players target the network edge for growth

Part 1: Coherent developments

The market for optical links for reaches between 10km and 120km is emerging as a fierce battleground between proponents of coherent and direct-detection technologies. 

Interest in higher data rates such as 400 gigabits is pushing coherent-based optical transmission from its traditional long-distance berth to shorter-reach applications. “That tends to be where the growth for coherent has come from as it has migrated from long-haul to metro,” says Tom Williams, senior director of marketing at Acacia Communications, a coherent technology supplier.

Williams points to the Optical Internetworking Forum’s (OIF) ongoing work to develop a 400-gigabit link for data centre interconnect. Dubbed 400ZR, the project is specifying an interoperable coherent interface that will support dense wavelength-division multiplexing (DWDM) links for distances of at least 80km.

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.

    Acacia looks to co-package its coherent PIC and DSP-ASIC

    • Acacia Communications is working to co-package its coherent DSP and its silicon photonics transceiver chip. 
    • The company is also developing a digital coherent optics module that will support 400 gigabit. 

    Acacia Communications is working to co-package its coherent DSP and its silicon photonics transceiver chip. The line-side optical transceiver company is working on a digital coherent optics module that will support 400 gigabits.

    Acacia announced last November that it was sampling the industry’s first CFP2 Digital Coherent Optics (CFP2-DCO) that supports 100- and 200-gigabit line rates. The CFP2-DCO integrates the DSP and its silicon photonics chip within a CFP2 module, which is half the size of a CFP module, with each chip packaged separately.

    NeoPhotonics samples its first CFP-DCO products

    NeoPhotonics has entered the fray as a supplier of long-distance CFP pluggable modules that integrate the coherent DSP-ASIC chip with the optics. 

    The company has announced two such CFP Digital Coherent Optics (CFP-DCO) modules: a 100 gigabit-per-second (Gbps) module and a dual-rate 100Gbps and 200Gbps one.

    “Our rationale [for entering the CFP-DCO market] is we have all the optical components and the [merchant coherent] DSPs are now becoming available,” says Ferris Lipscomb (pictured), vice president of marketing at NeoPhotonics. “It is possible to make this product without developing your own custom DSP, with all the expense that entails.”

    600-gigabit channels on a fibre by 2017

    NeoPhotonics has announced an integrated coherent receiver that will enable 600-gigabit optical transmission using a single wavelength. A transmission capacity of 48 terabits over the fibre’s C-band is then possible using 80 such channels.

    NeoPhotonics’ micro integrated coherent receiver operates at 64 gigabaud per second (Gbps), twice the symbol rate of deployed 100-gigabit optical transport systems and was detailed at the recent ECOC show.

    Current 100Gbps coherent systems use polarisation-multiplexing, quadrature phase-shift keying (PM-QPSK) modulation operate at 32 gigabaud per second. “That is how you get four bits [per symbol],” says Ferris Lipscomb, vice president of marketing at NeoPhotonics.
