Microchip and Acacia Collaborate on 400G Pluggable Coherent Optics for Data Center Routing, Switching, and Metro OTN Platforms
October 06, 2021
Bandwidth growth, driven by the expansion of data centers and 5G network build-outs, is expected to drive the need for faster coherent Dense Wavelength Division Multiplexing (DWDM) pluggable optics. Consequently, Data Center Interconnect (DCI) and metro Optical Transport Network (OTN) platforms are transitioning from 100/200G to 400G pluggable coherent optical modules to support these hyper-connected architectures.
Microchip Technology Inc. and Acacia, now part of Cisco, are bringing interoperable solution sets consisting of Microchip’s DIGI-G5 OTN processor and META-DX1 terabit secured-Ethernet PHY and Acacia’s 400G pluggable coherent optics. The purpose of the collaboration is to establish an ecosystem to support 400G CFP2-DCO, QSFP-DD and OSFP modules for the 400ZR specification as well as the OpenZR+ and Open ROADM Multi-Source Agreement (MSA) applications.
The collaboration enables the use of 400G coherent pluggables in OTN and Ethernet systems as follows:
- For converged packet/OTN optical platforms, Microchip’s DIGI-G5 and Acacia’s 400G CFP2-DCO module are designed to enable terabit-class OTN switching line cards, muxponders, and switchponders. The DIGI-G5 interoperates with Acacia’s 400G CFP2-DCO module using a Flexible OTN or NxOTU4 interface to efficiently support OTN traffic, including Open ROADM MSA interface modes and 200G/400G ITU-T standards currently being drafted.
- For compact modular optical systems, Microchip’s META-DX1 and Acacia’s 400ZR and OpenZR+ modules are designed to enable 400G flexible line rate muxponders/transponders with support for multiple client optics types including QSFP28, QSFP-DD, and OSFP modules, helping service providers to transition from 100 GbE to 400 GbE using the same hardware.
- For data center routing and switching platforms, Microchip’s META-DX1 and Acacia’s 400ZR and OpenZR+ modules are designed to enable dense 400 GbE or FlexE with per port MACsec encryption coherent line cards. This helps customers use IP routers/switches over DWDM (IPoDWDM) infrastructure in DCI deployments.
