The latest data centre architectures and increased traffic drive higher bandwidth requirements between data centres. To address this challenge, system developers must streamline the development of a new generation of 1.2Tbps (1.2T) transport solutions across a wide range of client configurations. This requires that today’s terabit-scale Ethernet PHY devices and coherent optical modules interoperate with each other in DCI and metro transport networks. Microchip Technology has worked with Acacia to demonstrate the fourth generation of interoperability between Microchip’s META-DX2 Ethernet PHY family and Acacia’s Coherent Interconnect Module 8 (CIM 8).
The two companies’ interoperable devices enable low-power, bandwidth-optimised, scalable solutions for pluggable optics in DCI and transport networks. They supply three key benefits as they jointly enable high-capacity, multi-rate muxponders for optical transport platforms:
The META-DX2 family, through its META-DX2+ PHY, uses its unique Lambda Splitting feature to split 400GbE or 800GbE clients across multiple wavelengths driven by the CIM8 modules. This maximises the capacity between data centres in rate configurations such as 3 x 800GbE over 2 x 1.2Tbps waves or 5 x 400GbE over 2 x 1Tbps waves.
The companies have jointly verified successful SerDes interoperation at up to 112G per lane for Ethernet and OTN clients, which reduces design validation and system qualification requirements.
The META-DX2+ crosspoint and gearbox functions enable 100GbE to 800GbE client modules to connect with full bandwidth to CIM8 modules.
“This interoperability extends a long-established partnership with Acacia to help accelerate and optimise the build-out of cloud computing and AI-ready optical networks while reducing development risk for our customers,” said Maher Fahmi, vice president for Microchip’s communications business unit. “Our META-DX2 is the first solution of its kind to integrate 1.6T of encryption, port aggregation and Lambda Splitting into the most compact 112G PAM4 device in the market.”
“With Acacia’s CIM 8 coherent modules verified to interoperate with Microchip’s META-DX2 devices, we see this as a robust solution that reduces system time-to-market,” said Markus Weber, senior director DSP product line management of Acacia. “The compact size and power efficiency of our CIM 8 coherent modules were designed to help network operators deploy and scale capacity of high-bandwidth DWDM connectivity between data centres and throughout transport networks.”
