Molex says it is ramping production of its commercially available 400G ZR QSFP-DD pluggable coherent optical transceivers to support ever-increasing demands for advanced Data Centre Interconnect (DCI) solutions.

Designed in compliance with the Optical Internetworking Forum (OIF) 400G ZR standard, Molex’s 400G ZR is claimed to be among the first standards-based, pluggable coherent optical modules to be commercially available in volume. In addition, the 400G OpenZR+, which is slated for availability in Q2, extends reach from 120km to about 600km at low power consumption to enable 12.8T in 1RU switch or router chassis.

Molex has also completed experimental verification of 400 Gbps data transmission over DCI ZR distances in a 75 GHz spaced DWDM link with amplification in an Open Line System (OLS). Using the Molex 400G ZR QSFP-DD transceiver modules in conjunction with 75 GHz OLS increases bandwidth capacity of optical fibres in a DCI application and can decrease the cost per bit significantly.

“Molex is meeting the need for faster transmission speeds both between and inside next-gen data centres,” said Joseph Chon, director, Coherent Technology and Product Line Management, Molex Optoelectronics. “By ramping commercialisation and production of the 400G ZR product line, we can enable mega-cloud data centre operators to better address a vast range of high-density, bandwidth-intensive applications.”

In related news, Molex is collaborating with Marvell to further enable simplified, more reliable edge and data centre networks. Today, Marvell issued a news release announcing plans to work with Molex on a 400G QSFP-DD optical module based on the Marvell® Deneb™ Coherent DSP (CDSP) while fully supporting the OpenZR+ Multi-Source Agreement (MSA).

Molex will be present at OFC 2022 in the Corporate Village Space #2023
