Inphi and NeoPhotonics have completed an interoperability demonstration of OIF 400ZR implementation agreement-compliant coherent transceivers, operating across the C-band over 120km of optical fibre.
Transceiver pairs were successfully linked. These consisted of Inphi’s Colorz II QSFP-DD with its Canopus 7nm Coherent DSP, and the NeoPhotonics 400ZR ClearLight OSFP. Both transceivers carried error-free traffic over a typical data centre interconnect (DCI) link configuration (amplified over 120km of fibre) at several wavelengths across the C-Band using Arista 7060 data center switches.
The successful interoperation of the transceivers demonstrates the availability of interoperable coherent transceivers for the 400ZR ecosystem. This is a key step in enabling the next generation of DCI links. The benefits of 400ZR pluggable transceiver modules include a reduction in the cost and power consumption of DCIs by eliminating the transport network equipment layer.
Josef Berger, AVP of marketing, optical interconnect at Inphi said: ‘This demonstration proves the readiness to deliver the flexibility of high bandwidth DWDM connectivity between data centres with the ability to rapidly scale capacity and meet our customers’ demands for standards-based pluggable coherent solutions.’
Marc Stiller, vice president of coherent modules for NeoPhotonics added: ‘Supporting the interoperable CFEC standard, as defined by OIF, has been a critical part of our design effort, and we’re very pleased to announce this milestone as we continue to work with customers to implement this game-changing technology.’
