The PM5440 DIGI-120G family represents Microchip's 3rd generation Metro OTN processing solution for Wavelength Division Multiplexing (WDM) Platforms, Reconfigurable Optical Add-Drop Multiplexers (ROADMs) and Packet Optical Transport Platforms (P-OTP/PE-OTNs). This device is a high-capacity, channelized, single-chip OTN processor that provides unprecedented scalability and feature-integration to enable Metro OTN switching and transport deployments. The DIGI-120G enables power and cost efficient 12x10G/3x40G/100G line cards for OTN switching systems and Transponder/Muxponder/ADM cards with integrated ODU0/ODUflex support for OTN transport systems. The DIGI-120G provides a rich set of framing, mapping, multiplexing and switching resources for a variety of rates and protocols including OTN, SONET/SDH, Ethernet and Fiber Channel. It can be leveraged easily across multiple applications and multiple equipment platform types to reduce OEM development cost and accelerate time to market. The DIGI-120G family includes a hardware and software compatible lower capacity variant PM5441 DIGI-60G.
