By Telecom Lead Team: PMC-Sierra, a provider of semiconductors, announced that
its HyPHY family of OTN processors provides full architectural
support of the Optical Internetworking Forum (OIF)’s
new OTN-over-Packet-Fabric Protocol Implementation Agreement.
PMC’s HyPHY
20G and HyPHY 10G OTN processors provide a fully compliant
implementation of the OIF IA via the Constant Bit Rate Interface (CBRI) and OTN
Phase Signalling Algorithm (OPSA).
CBRI, which is compliant with the
Interlaken protocol, enables HyPHY to connect to a centralized packet/cell
switch fabric and is capable of supporting hybrid packet/OTN switched line card
designs.
The Optical Internetworking Forum’s
initiative aims to help the industry develop an ecosystem for interoperable OTN
switching at the silicon and optical equipment levels, which meets carriers’
needs to drive mass deployment of OTN switching in their networks.
Carriers worldwide are
adopting OTN switching as a method to provide sub-wavelength switching to their
converged optical transport infrastructure. The ability to combine OTN with
packet switching on the same platform provides them maximum flexibility in
network designs to optimize costs,” said Mark Pashan, general manager, optical
transport products, Tellabs.
The OIF IA defines a method for
switching OTN streams, including the newly standardized ODU0 and ODUflex
streams, over cell or packet switch fabric technology. This enables Packet
Optical Transport Platforms (P-OTPs) to be based on a single fabric, resulting
in significantly simpler designs that consume less power and shelf space.
With industry alignment and
our HyPHY multi-service OTN processing solutions in volume production, carriers
can now deploy OTN switching in their metro networks,” said Babak Samimi, vice
president of marketing and applications for PMC’s Communication Products
Division.
Last year,
PMC-Sierra announced multi-port EPON OLT System-on-Chip (SoC) solutions that
address the need to increase network functionality improve reliability and
reduce power consumption.
