OCTOBER 22, 2008 -- PMC-Sierra Inc. (search for PMC-Sierra) has announced the availability of what it claims is the industry's most highly integrated GPON devices for FTTH deployments.
PMC-Sierra's new GPON System-On-Chip (SoC) devices include the PAS7401 GPON ONT, the MSP7162 GPON Gateway, and the PAS5211 four-port GPON OLT. They feature PMC-Sierra's GigaPASS architecture, which is already deployed in more than six million PON devices and is enhanced for WT-156 compliance, say company representatives. These devices are PMC-Sierra's second-generation GPON offerings and include complete reference designs and software packages. All have proven interoperability with a wide range of commercial GPON systems, says PMC-Sierra.
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. According to the company, the designs implement advanced 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 GPON networks.
The GPON OLT reference design, meanwhile, 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, says the company.
The PAS7401 integrates a GPON MAC, a VoIP sub-system, 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 TranslationI(NAT), and quality-of-service (QoS) features, notes the company. 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/secIports, an embedded controller, and a GigaPASS bridge performing advanced classification, queuing, and filtering at line-rate. Sophisticated DBA accelerators and embedded optical supervision cores can lower the network deployment and maintenance costs, say PMC-Sierra representatives. The 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.
"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," contends 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, MSP7162, and PAS5211are sampling now to PMC-Sierra's customers; reference designs are also available now to GPON equipment manufacturers.
