Class 60 coherent modulator and receiver are ready for 96Gbaud optical systems

Laser and optophotonic specialist, NeoPhotonics has announced it is shipping Class 60 versions of its coherent driver-modulator (CDM) and intradyne coherent receiver (Micro-ICR) in initial quantities to multiple customers.

The Class 60 CDM and Micro-ICR are mechanically compatible with the Class 40 counterparts, said NeoPhotonics. They provide a natural upgrade path to higher baud rates supporting data rates that include 800G applications.  Optical system performance improvements enabled by operation at these increased baud rates enable customers to pack more data over longer distances for better economics, lower cost per bit, lower operating expenses and lower power consumption, all under the same hardware envelope as the currently NeoPhotonics Class 40 components.

According to NeoPhotonics, the higher symbol rates increase data capacity while maintaining superior optical signal-to-noise ratio (OSNR) and reach performance, for the highest speed-over-distance use. The new components are available in compact form factor packages suitable for use in pluggable modules and compact daughter cards. The Class 60 Coherent components increase the 3dB bandwidth from 40GHz to 60GHz, compared with the Class 40 components. The CDM and Micro-ICR work together to enable customers to implement single wavelength data transmission near 1Tbit per second over data centre interconnect (DCI) distances, as well as 400 to 500Gbits per second transmission over long haul distances.

The NeoPhotonics Class 60, polarisation-multiplexed, coherent driver modulator (CDM) features a co-packaged InP modulator with four linear, high bandwidth, differential drivers, and is designed for low modulation voltage – or V-Pi -, low insertion loss and a high extinction ratio. The compact package complies with the form factor of the OIF Implementation Agreement OIF-HB-CDM-01.0. The Class 60 high bandwidth Micro-ICR is designed for 96GBaud symbol rates, essentially tripling the rate of standard 100G ICRs, said NeoPhotonics. Its compact package complies with the OIF Implementation Agreement OIF-DPC-MRX-02.0.

These components are designed to work together with NeoPhotonics’ Nano narrow line width external cavity tunable laser, which cuts the size approximately in half compared to current Micro-ITLAs, while featuring industry leading line width, low phase noise and low electrical power consumption.

In addition to the Class 60 coherent modulators and receivers, the company is “extending the bandwidth of our Indium Phosphide coherent integration platform by developing Class 80 components for 130 Gbaud operation as we continue to serve the highest speed-over-distance applications,” said Tim Jenks, chairman and CEO of NeoPhotonics.

NeoPhotonics develops and manufactures lasers and optoelectronic products that transmit, receive and switch high-speed digital optical signals for cloud and hyper-scale data centre internet content provider and telecomms networks. The company says its products enable cost-effective, high-speed over distance data transmission and efficient allocation of bandwidth in optical networks.

NeoPhotonics has headquarters in San Jose, California, USA and ISO 9001:2015 certified engineering and manufacturing facilities in the USA, Japan and China.
