Microchip and Acacia Test Interoperability of their Products


Microchip and Acacia Communications join hands together to offer industry’s first Flexible Rate Optical Transmission Up to 600G. The partners demonstrated the interworking of the Microchip’s DIGI-G5 Optical Transport Network Processor with Acacia’s AC1200 coherent module. The market is driving towards hyper-connected architectures together with the transition from 100G to data rates upto 600G. Microchip’s subsidiary company Microsemi Corporationa and Acacia Communications collaborates to ensure interoperability between their solutions.

Microchip’s DIGI-G5 Optical Transport Network (OTN) processor and Acacia’s AC1200 Coherent Module together can offer scalable data transmission rates upto 600G. The objective of the companies’ collaboration is to enable the industry’s first flexible rate system architectures with an established ecosystem to support the market’s transition to 200G, 400G, 600G and flexible rate OTN networks built with new Flexible Ethernet (FlexE) and OTUCn protocols.

Telecommunication service providers can deploy higher bandwidth Ethernet connectivity at a faster rate and at a lower cost with Optical Internetworking Forum’s (OIF) FlexE protocol. (The Optical Internetworking Forum (OIF) is a prominent non-profit consortium that promotes the development and deployment of interoperable computer networking products and services through implementation agreements (IAs) for optical networking products and component technologies including SerDes devices.) FlexE was designed to provide up to 30 percent greater bandwidth efficiency compared to traditional Ethernet link aggregation (LAG) with fewer limitations. Combining it with OTUCn and tunable fractional dense wavelength division multiplexing (DWDM) transmission brings service providers the potential to improve their OTN network capacity by up to 70 percent.

As the first OTN processor to support FlexE and OTUCn protocols, Microchip’s DIGI-G5 delivers the silicon and software required to launch new terabit scale line cards with flexible rate optical interfaces for packet optical transport platforms. By combining the DIGI-G5 and AC1200, next generation architectures will help to support the market’s growing demand for metro and data center interconnect networks requiring 100G+ connectivity that can be rate adjusted to maximize bandwidth.

The processor DIGI-G5 allows the optical transport system partners to deliver terabit-class OTN switching line cards at 50 percent less power per port while enabling flexible rate ports and protocols up to 600G. The demonstration of interworking of the DIGI-G5 with Acacia’s AC1200 coherent module highlights that the ecosystem is ready to support the market transition to these new protocols, rates and multi-terabit architectures.

The partners’ solutions will enable the OTN connections over two 600G tunable DWDM wavelengths with flexible transmission three-dimensional (3D) shaping features. These features, which include fractional quadrature amplitude modulation (QAM) and adaptive baud rate optimize transmission reach and capacity, approaching theoretical limits on a wide range of network configurations, in a power efficient manner.
