PMC-Sierra launches Quad-Port EPON OLT SoCs for FTTH deployments

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.

The PAS5400 devices integrate four 1Gb/s EPON MACs and are scalable to enable high-density OLT equipment. The new family of four-port devices integrates the most advanced PON capabilities on the market, including: integrated traffic management and packet processing, advanced power save modes that allow remote power down of customer premises equipment, in-band optical fiber testing and support for mobile backhaul.

“Carriers are looking for ways to deliver new services and higher bandwidth to a growing base of subscribers, while improving network reliability and reducing operational cost,” said Raphael Sankar, vice president and co-general manager of PMC’s FTTH division. PMC is the only provider that can deliver this level of innovation across a complete portfolio of solutions for EPON, GPON and 10G PON with
maximum software reuse, and this solidifies our leadership in the optical fiber access market segment.

PMC’s new EPON OLT family includes three SoCs that comply with IEEE 802.3ah and China carrier specifications for EPON networks: PAS5404 with ‘lite’ traffic management, PAS5414 with fully featured traffic management, and PAS5424 with fully featured traffic management and a cascading option that eliminates the need for an aggregation switch on the OLT line card.

All devices integrate four 1Gb/s upstream and downstream PON channels, including the EPON MAC, SERDES and fast-locking Burst Mode CDR (BMCDR), and support SGMII, XAUI and RXAUI backplane interfaces. On-chip fiber Automatic Protection Switching (APS)
enables a rapid switch-over in cases of failures in the optical network.

PMC’s OLT solutions include reference designs and software design kits (SDK). The complete EPON OLT software package is fully compatible with PMC’s widely deployed PAS5201 and PAS5204 1G-EPON OLT software and with PAS8400 10G-EPON software and is portable to any real-time operating system, such as Linux and VxWorks, and to any processor.

The SDK features an EPON protocol stack, a complete set of traffic management drivers, IEEE 802.3ah OAM protocol, including operator-specific stacks, optical diagnostics functions, and pre-integrated peripheral drivers.
