NeoPhotonics showcasing 64Gbaud coherent product suite: higher-symbol-rate components increase OSNR and reach for coherent transport
In stand 340 at the European Conference on Optical Communications (ECOC 2017) in Gothenburg, Sweden (18-20 September), 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) is showcasing its suite of 64Gbaud optical components for coherent systems operating at 600G and above.
Headlining the product suite is the 64Gbaud micro-modulator (Micro-MOD) with integrated drivers, which has now begun sampling. NeoPhotonics has also begun shipping its 64Gbaud micro-intradyne coherent receiver (Micro-ICR) and it low-profile ultra-narrow-linewidth tunable laser for 400G and 600G applications.
The highest data rates depend on NeoPhotonics 64Gbaud coherent product suite. 64Gbaud components double the symbol rate over standard 100G (32Gbaud) coherent systems. Higher symbol rates increase bandwidth while maintaining superior optical signal-to-noise ratio (OSNR), spectral density and reach performance. For this reason, system designers choose to move to higher baud rates before higher-order modulation when they need to increase the capacity per wavelength.
- 64Gbaud Micro-MOD (CDM): NeoPhotonics’ 64GBaud, polarization-multiplexed, quadrature micro-modulator is currently being sampled to major customers and features a co-packaged indium phosphide (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.
- 64Gbaud Micro-ICR: NeoPhotonics’ Class 40 high-bandwidth micro-intradyne coherent receiver is in volume production and is designed for 64Gbaud symbol rates, doubling the RF bandwidth of standard 100G ICRs. The 64Gbaud Micro-ICR supports higher-order modulation such as 64 QAM (quadrature amplitude modulation).
- Low profile Micro-TL: NeoPhotonics’ ultra-narrow-linewidth external cavity tunable laser has been proven in volume production and is now configured in a smaller, lower-profile package, designed to meet the stringent requirements for packaging density in pluggable modules (including at 400G and 600G data rates). The external cavity laser has a significantly narrower linewidth, which is advantageous for higher-order modulation formats.
“Our 64Gbaud symbol rate optical components for coherent transport provide system designers with the optical tools that match increases in DSP [digital signal processing] capability to enable higher spectral densities and longer reaches,” says chairman & CEO Tim Jenks. “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,” he adds.
In addition, as part of the ECOC Market Focus Program, Dr Winston Way, NeoPhotonics’ chief technology officer, Systems, is presenting a paper ‘Applications of 64 Gbaud Optical Components and Modules’ on 20 September (13:50-14:20) at the Market Focus Theatre in the Exhibition Hall.
At ECOC, NeoPhotonics is exhibiting its suite of standard- and small-form-factor PIC-based components, including a full suite of 64Gbaund coherent devices for 100G to 600G coherent line-side applications, along with its 100G client-side and data-center CFP2-LR4 transceivers, as well as its multi-cast switches for ‘contentionless’ ROADMs (reconfigurable optical add/drop multiplexers).
