NeoPhotonics’ 64GBaud coherent optical components selected by tier-1 customers for 600G system development

NeoPhotonics Corp of San Jose, CA, USA (a vertically integrated designer and manufacturer of hybrid photonic integrated optoelectronic modules and subsystems for high-speed communications networks) says that its suite of 64GBaud optical components for coherent systems are being used by multiple major customers to develop systems with 600G-per-wavelength transport capacity.

The suite consists of three critical optical components: a 64GBaud CDM (coherent driver modulator) plus a 64GBaud ICR (coherent intradyne receiver) and finally an ultra-narrow-linewidth tunable laser. These work together to enable the implementation of single-wavelength 600G or dual-wavelength 1.2T data transmission over data-center interconnect (DCI) distances of 80km.

Three leading OEM customers have elected to use all three components in their development, while additional customers have elected to use a subset of the 64GBaud coherent component suite. The components also support 400G over metro distances of 400-600km using 64GBaud and 16 QAM or 200G over long-haul distances of greater than 1000km using 64GBaud and QPSK.

64GBaud components double the symbol rate over standard 100G (32GBaud) coherent systems. Higher symbol rates increase data capacity while maintaining superior optical signal-to-noise ratio (OSNR), spectral density and reach performance. All of these components are available in compact-form-factor packages suitable for pluggable modules and compact daughter cards:

  • 64GBaud CDM: NeoPhotonics’ 64GBaud polarization-multiplexed, quadrature coherent driver modulator (CDM) is shipping in limited availability and features a co-packaged indium phosphide (InP) modulator with a linear, high-bandwidth, differential driver in a compact package designed to be compliant with the anticipated OIF Implementation Agreement.
  • 64GBaud micro-ICR: NeoPhotonics’ Class 40 high-bandwidth micro-intradyne coherent receiver (micro-ICR) is in volume production and is designed for 64GBaud symbol rates, doubling the bandwidth of standard 100G ICRs. The compact package is designed to be compliant with the OIF Implementation Agreement OIF-DPC-MRX-02.0.
  • Low-profile Micro-TL: NeoPhotonics’ ultra-narrow-linewidth external cavity tunable laser features very low phase noise and power consumption and has been proven in volume production. It is now configured in a smaller, lower-profile package that is compliant with the OIF Implementation Agreement OIF-MicroITLA-01.

In addition to these shipping products, NeoPhotonics has introduced its next generation of coherent products, which approximately halve the size of coherent optics while featuring the same high performance required for 400G and 600G per wavelength. The coherent optical subassembly (COSA) integrates NeoPhotonics’ 64GBaud coherent driver modulator with its 64Gbaud coherent receiver in a very compact form factor. Alongside this, NeoPhotonics introduced a ‘Nano’ ultra-narrow-linewidth external cavity tunable laser, which again approximately halves the size while featuring industry-leading linewidth and phase noise and with low electrical power consumption.

These next-generation products were demonstrated in operation at the Optical Fiber Conference (OFC 2018) exhibition in March, both individually and incorporated into a compact 400G pluggable module.

“We are working closely with customers to provide a matched suite of high-speed optical components for 600G per wavelength to enhance system performance and reduce time to market,” says chairman & CEO Tim Jenks. “With our next-generation highly integrated COSA, operating at 64 Gbaud and beyond, and our Nano-Tunable Laser, we are working to enable highly compact pluggable 400G modules,” he adds.

NeoPhotonics is exhibiting its suite of coherent components for 600G and 1.2T in booth 426 at the European Conference on Optical Communication (ECOC 2018) in Rome, Italy (24-26 September) along with its broad family of products for high-speed applications.

In addition, in the Exhibition Market Focus session ‘Optical Network Agility/Software Defined Networks’ on 25 September (16:10pm), NeoPhotonics’ CTO systems Dr Winston Way is presenting a paper ‘Next-Generation Coherent Pluggable Transceivers in a CDC ROADM Based Optical Network’.
