Product Overview
The PM5420 HyPHY 20G device is a feature-rich, high-capacity
system-on-a-chip solution that enables universal multi-rate, multiservice
line cards, transponder cards, and muxponder cards for
Multi-Service Provisioning Platforms (MSPPs), Wavelength Division
Multiplexing (WDM) Platforms, Reconfigurable Optical Add-Drop
Multiplexers (ROADMs), Optical Transport Platforms (OTPs),
Packet-OTPs, and Optical Access Platforms.
The HyPHY 20G delivers unprecedented single-chip scalability and
feature integration to enable optimal footprint, power, and cost
efficiency. The HyPHY 20G 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 20G introduces 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
Benefits
- Carrier OPEX and CAPEX savings:
-
Simplifies equipment deployment and network
management by enabling hybrid TDM/packet platforms
- Dramatically reduces cost of ownership by simplifying line
card inventory management
- Unprecedented service delivery flexibility:
- Supports per-port configurable OTN, SONET/SDH,
Ethernet, SAN and bit transparent client services
- Rich suite of client service mappings into OTN and
SONET/SDH
|
-
Processor-based Carrier Ethernet:
- Flexible implementations of Synchronous Ethernet,
IEEE 1588 Precision Timing Protocol (PTP), and Ethernet
Link OAM (IEEE 802.3ah)
-
Optimized power and footprint for OEMs:
- Direct connect to SFP, SFP+ and XFP modules for all rates
with no external SERDES or PLL components required
- All frequencies derived from a single 155.52 MHz
reference clock
- Single-chip solution for muxponders, transponders and
optical access platforms
- Glueless interconnect to many off-the-shelf NPs and
fabrics
