Original Press Release:

PM5426 HyPHY 10G Optical Access Multi-Rate / Multi-Protocol PHY

Product Overview

The PM5426 HyPHY 10G device is a feature-rich, system-on-a-chip solution optimized to enable a new generation of Compact Optical Access platforms for the network edge. HyPHY 10G addresses multi-service transponder and muxponder applications for Multi- Service Provisioning Platform (MSPPs), Wavelength Division Multiplexing (WDM) Platforms, Reconfigurable Optical Add-Drop Multiplexers (ROADMs), Optical Transport Platforms (OTPs), Packet- OTPs, and Optical Access Platforms.

The HyPHY 10G delivers single-chip scalability and feature integration to enable optimal footprint, power, and cost efficiency. The HyPHY 10G provides a rich set of framing, mapping and multiplexing resources for a variety of protocols, including OTN, SONET/SDH, Ethernet, Fibre Channel, ESCON, FICON, and multi-rate bit transparent services such as video.

The HyPHY 10G supports an array of innovative technologies:

Rate-Agile Programmable Transceiver IO (RAPTR IO): Gapless rate-agile SERDES from 16 Mbits to 4.25 Gbit/s for direct connect to SFPs and from 8.5 Gbit/s to 11.32 Gbit/s for direct connect to SFP+ and XFP modules

OTN Phase Signaling Algorithm (OPSA): Improve jitter performance when transporting clients over OTN

Efficient sub-ODU1 mapping of client data into OTN

Packetized OTN interface to carry ODUks across system fabrics
