PMC-Sierra or PMC performs several operations related to semiconductors, based on transforming optical, storage, and mobile networks. It has declared that its HyPHY series of OTN processors leverage the OTN-over-Packet-Fabric Protocol Implementation Agreement (IA) of the Optical Internetworking Forum (OIF).
Supporting the drive mass deployment of OTN switching in carrier networks, the OIF intends to facilitate the industry in designing an environment for interoperable OTN switching at the optical and silicon equipment levels.
With the new ODU0 and ODU flex streams, the OIF IA devises a method for switching OTN streams over cell or packet switch fabric technology. As a result, Packet Optical Transport Platforms (P-OTPs) will be supported on a single fabric, providing low power simpler designs, occupying less shelf space. The growth and advancement of P-OTPs will increase over the years as they are capable of offering both OTN switching and packet switching in a single platform. This will facilitate optical networks that originate from pure TDM (SONET/SDH) to converged packet and OTN architectures. The OIF agreement is expected to be delivered in January 2012.
The HyPHY 20G and HyPHY 10G OTN processors of PMC fulfills the OIF IA protocol, through the OTN Phase Signalling Algorithm (OPSA) and Constant Bit Rate Interface (CBRI). CBRI, relies with the Interlaken protocol and facilitates HyPHY to connect to a centralized packet/cell switch fabric, thereby leveraging hybrid packet/OTN switched line card designs. The advantages of OPSA include reassembly, segmentation with frequency or phase encoding or decoding for assisting OTN over a packet/cell fabric. The HyPHY provides low-power, single-chip, multi-service OTN muxponder and transponder line cards.
