PMC Disrupts 100G Economics With Industry’s First OTN Processor Enabling Virtualization Of Optical Network Bandwidth For Big Data

PMC® (Nasdaq:PMCS), the semiconductor innovator transforming networks that connect, move and store big data, announced today the introduction of PM5440 DIGI 120G, the industry’s only single-chip OTN processor supporting 10G, 40G and 100G speeds for OTN transport, aggregation and switched deployments. DIGI 120G allows for the efficient sharing and dynamic assignment of network resources, enabling OTN networks to effectively virtualize optical network bandwidth to meet the elastic traffic demands of Big Data. This unprecedented level of silicon integration facilitates the most cost effective designs, engineering efficiency, and lowest power approach to OTN system solutions.

Optical transport networks play a critical role in providing the interconnect infrastructure required to efficiently and reliably deliver cloud-based services. Continued growth in mobile data traffic and the projected 3X growth in datacenter driven WAN traffic 1 are the catalysts behind industry’s need for 100G connectivity to aggregate the increasing deployment of 10G ports from the metro edge. To unlock the full value of 100G networks, service providers are architecting their transport infrastructure to enable dynamic bandwidth allocation with granularity from 100Gbps down to 1Gbps, without interruption to network traffic, in order to ‘virtualize’ the optical network bandwidth.

OTN allows for flexible aggregation and switching from 1G to 100G

With today’s networks dominated by 1G & 10G services, traditional point-to-point OTN transponders do not efficiently map these service rates to 100G due to a lack of OTN multiplexing granularity to 1Gbps. PMC’s new DIGI 120G supports OTN Transport, OTN aggregation and OTN switching. Multiservice OTN muxponders and OTN switching cards using DIGI 120G will enable efficient aggregation and grooming of lower speed services into 100G.

As the industry’s first OTN processor to support on-demand re-sizing of ODUflex from 1G to 100G, as well as 10G, 40G and 100G speeds, DIGI 120G allows OEMs to deliver a full suite of multiservice OTN switched cards for Packet Optical Transport Platforms (P-OTP) and muxponders for ROADMs. Numerous configurations are supported, including 12 ports at 10Gbps, 3 ports at 40Gbps or 1 port at 100Gbps. DIGI 120G’s unique single-chip architecture allows OEMs to leverage a common hardware and software investment to rapidly build-out a portfolio of line cards, translating into the lowest bill of material, lowest power, and fastest time-to-market.
