PM5991

DIGI-G4 is Microchip's fourth-generation OTN processing solution for next-generation OTN switching and packet-optical transport (POTP/P-OTN), WDM/ROADM, and hyperscale data center interconnect (DCI) equipment. Building on the innovations in Microchip's DIGI-120G, which is widely deployed in service provider and hyperscale data center WAN networks today, DIGI-G4 is a 4x100G multi-service OTN processor, scaling line card capacity by 4x, while reducing power per port by 50 percent,as compared to previous generation OTN processors. DIGI-G4 addresses the requirements of SDN-ready, encrypted optical transport infrastructure. Reusing Microchip's proven, service provider-qualified DIGI family OTN switching software development kit (SDK), DIGI-G4 can be leveraged across multiple applications and equipment platforms, providing OEMs with the lowest risk, fastest time-to-market and lowest cost of development.

Variants available with OTN encryption (PM5990) and without OTN encryption (PM5991).
