Collaboration creates 400G OpenZR+ pluggable optical module

Marvell and Molex have announced a collaboration to deliver a 400G QSFP-DD optical module that supports the OpenZR+ Multi-Source Agreement (MSA). 

Based on the Marvell Deneb Coherent DSP (CDSP), the new Molex 400G QSFP-DD small form-factor pluggable module is designed to deliver high performance and scalability while reducing power and total cost of ownership, enabling simplified, more reliable edge and data centre networks. In addition, the Marvell Deneb CDSP continues to drive a standards-based ecosystem for multi-vendor interoperability, which is critical to accelerating a wide adoption of IP-over-DWDM (IPoDWDM).

Growing market adoption of IPoDWDM is driving increased use of coherent pluggables in switches and routers to eliminate separate full-function optical transport boxes, thereby reducing cost and complexity in data centre applications as well as edge networks for global carriers. Deneb enables OpenZR+ compliant pluggable modules in popular form factors like QSFP-DD to support interoperability across these routers and switches and provides a seamless upgrade path across multiple platforms. OpenZR+ solutions enable carriers to go beyond the ZR reach to address metro edge and data centre applications.

Joseph Chon, director of coherent technology and product line management at Molex Optoelectronics said: ‘Our collaboration with Marvell has enabled us to deliver 400G OpenZR+ coherent pluggable modules for switches and routers optimised for DCIs. Molex’s coherent optical modules pair the advantages of Marvell’s Deneb DSP with the high performance of Molex’s transceiver technology to deliver power-efficient, high performance and cost-effective solutions that will serve the industry’s need for disaggregated network solutions.’

Samuel Liu, senior director, product line management, Marvell said: ‘Marvell’s CDSP is enabling disruptive solutions that address the accelerating bandwidth network requirements of carrier and cloud operators. Our collaboration with Molex is an important milestone and proof point in how we are building a large open ecosystem to help accelerate the adoption of IPoDWDM.’
