NeoPhotonics offers 64-GBaud coherent line for 600G and up

NeoPhotonics Corp. (NYSE: NPTN) used the European Conference on Optical Communications (ECOC) 2017 in Gothenburg, Sweden last week to showcase its line of 64-GBaud optical components for coherent systems operating at 600G and above.

NeoPhotonics Corp. (NYSE: NPTN) used the European Conference on Optical Communications (ECOC) 2017 in Gothenburg, Sweden last week to showcase its line of 64-GBaud optical components for coherent systems operating at 600G and above.

The product line includes the 64-GBaud micro modulator (Micro-MOD) with integrated drivers, which NeoPhotonics says it has now begun sampling. NeoPhotonics has also begun shipping its 64-GBaud micro coherent receiver (Micro-ICR) and its low-profile ultra-narrow line-width tunable laser for 400G and 600G applications.

The highest data rates are based on NeoPhotonics 64-GBaud coherent product portfolio. 64-GBaud components double the symbol rate over standard 100G (32 GBaud) coherent systems. Higher symbol rates increase bandwidth while maintaining OSNR, spectral density, and reach performance, which is why system designers choose to move to higher baud rates before higher order modulation when a capacity per wavelength increase is required, says NeoPhotonics.

In March, NeoPhotonics unveiled the 64-GBaud, polarization-multiplexed, quadrature Micro-MOD at OFC 2017 in Los Angeles (see "NeoPhotonics offers 64-GBaud coherent micro-modulator for 400/600 Gbps"). The company says it has now begun sampling the 64-GBaud Micro-MOD (CDM) to major customers. The Micro-MOD features a co-packaged InP modulator with linear, high bandwidth, differential drivers in a compact package to operate in 400G and beyond pluggable modules that demand reduced size and power consumption.

NeoPhotonics announced the volume production of its Class 40 high bandwidth Micro-Intradyne coherent receiver as well. Designed for 64-GBaud symbol rates, the 64-GBaud Micro-ICR doubles the RF bandwidth of standard 100G ICRs and supports higher order modulation, including 64 QAM.

The company also announced that its Low Profile Micro-TL has been proven in volume production. The ultra-narrow linewidth external cavity tunable laser is now configured in a low-profile package designed to meet precise packaging density requirements in pluggable modules, such as those for 400G and 600G data rates. The external cavity laser features a narrow linewidth, accelerating high-order modulation formats.

"Our 64-GBaud symbol rate optical components for coherent transport provide system designers with the optical tools that match increases in DSP capability to enable higher spectral densities and longer reaches," said Tim Jenks, NeoPhotonics chairman and CEO. "Each of these products is based on our hybrid photonic integration technology and leverages our existing proven design platforms, which allows us to ramp production rapidly to match customer demands, while maintaining high quality and reliability."
