PMC-Sierra intros second-gen GPON devices

SEPTEMBER 29, 2008 -- PMC-Sierra Inc. has announced the availability of new GPON SoCs, which include the PAS7401 GPON ONT, the MSP7162 GPON Gateway, and the PAS5211 four-port GPON OLT.

SEPTEMBER 29, 2008 -- PMC-Sierra Inc. (search for PMC-Sierra) has announced the availability of new GPON SoCs, which include the PAS7401 GPON ONT, the MSP7162 GPON Gateway, and the PAS5211 four-port GPON OLT. They feature PMC-Sierra's GigaPASS architecture, which PMC-Sierra says is already deployed in more than 6 million PON devices and is enhanced for WT-156 compliance. These devices are PMC-Sierra's second-generation GPON SoCs and include complete reference designs and software packages; all have proven interoperability with a wide-range of commercial GPON systems, according to the company.

"By partnering with PMC-Sierra to supply industry-leading GPON access equipment, Dasan is able to leverage PMC-Sierra's extensive experience based on millions of FTTH field deployments," said Dr. Steve Lee, vice president and head of R&D, Dasan Networks, Inc. "Our partnership enables us to offer high-performance, low-cost triple-play GPON systems based on field-proven, flexible platforms that can easily meet carriers' current and future service requirements."

PMC-Sierra's ONT, Single-Family Unit (SFU), Multi-Dwelling Unit (MDU) and gateway reference designs are available for a range of user interfaces, including Gigabit Ethernet, Fast Ethernet, MoCA, POTS, USB, and WiFi. The designs implement power saving techniques that enable the use of smaller batteries in deployments where lifeline service is required, and reduce ONT power consumption to a minimum when not in use, reducing the cost and increasing the energy efficiency of GPONs, PMC-Sierra says.

The GPON OLT reference design provides complete line card functionality and implements a very low-latency upstream dynamic bandwidth allocation (DBA) algorithm, as well as optical supervision features, enabling higher network efficiency and lower maintenance costs.

"PMC-Sierra's new SoCs and reference designs enable our customers to offer GPON products with differentiated network and power performance at lower cost and shorter time to market," said Victor Vaisleib, vice president and general manager of PMC-Sierra's FTTH business unit. "This advanced generation of GPON products, including OLT, ONT and residential gateway devices, achieves all GPON market requirements for throughput, power consumption, and QoS."

The PAS7401 integrates a GPON MAC, a VoIP subsystem, an embedded controller, and GigaPASS bridge performing advanced classification, queuing, and filtering, with wire-speed throughput at all packet sizes. Advanced power saving modes can lower PON deployment costs by reducing battery backup unit expenses. The reference designs come with complete GPON ONT software, featuring GPON functions, QoS bridging, VoIP, SIP, and OMCI.

The MSP7162 leverages the PAS7401 features and adds gigabit-per-second IPv4 or IPv6 routing, Network Address Translation (NAT), and QoS features. The reference design includes complete GPON gateway software featuring an RG management application, GPON functions, bridging, routing, NAT and QoS, WiFi, VoIP and SIP, and OMCI.

The PAS5211 integrates four GPON MACs, a backplane interface of either one 10-Gbit/sec port or four 2.5-Gbit/sec ports, an embedded controller, and a GigaPASS bridge performing advanced classification, queuing and filtering at line rate. DBA accelerators and embedded optical supervision cores can lower the network deployment and maintenance costs. Its high-density OLT line card reference design comes with complete software, including GPON link management protocols, DBA algorithm, and an API layer that are portable to a variety of operating system and host processors.

The PAS7401, MSP7162 and PAS5211 are sampling now to PMC-Sierra's customers. Reference designs are also available now to "leading GPON equipment manufacturers."
