SUNNYVALE, Calif. -- March 18, 2013

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.

“Explosive packet traffic growth projected from cloud services, residential
broadband, and mobile backhaul is driving China Mobile to invest in scaling up
our optical transport network to support 100G,” said Bill Huang, General
Manager of China Mobile Research Institute. “To maximize our 100G investment,
we need OTN solutions from the 100G ecosystem that allow us to manage the
optical bandwidth efficiently so we can economically deploy 100G and OTN
switching on a wide scale.”

DIGI 120G Delivers Industry-Leading Innovations

Reducing line card power and bill-of-material by more than fifty percent, DIGI
120G stands uniquely differentiated as:

  *Industry’s only single-chip solution delivering 12x10G, 3x40G or 1x100G
    port densities
  *Industry’s highest number of 10G ports enabling 2x higher density 10G OTN
    line cards
  *Industry’s highest gain 40G/100G enhanced-FEC extending optical reach by
    2x vs GFEC
  *Industry’s only 120G OTN solution with OIF’s OTN-over-Packet Fabric
    Protocol (OFP)
  *First OTN processor to enable hitless packet traffic scaling with ITU-T’s
  *Flexible per port client-mapping of OTN, Ethernet, Storage, IP/MPLS and
  *Synchronous Ethernet (SyncE), 1588v2 Precision Time Protocol (PTP), and
    Ethernet Link OAM (802.3ah) delivering per port Carrier Ethernet

“The optical transport network infrastructure needed to support Big Data
requires efficient sharing and dynamic allocation of the optical network
bandwidth,” said Babak Samimi, vice president of marketing and applications
for PMC's Communications Business Unit. “Our DIGI 120G brings innovations that
disrupt the economics of 100G by responding to the industry’s need to move
towards dynamically configurable optical transport networks for delivering
cloud services.”
