GPON devices for worldwide FTTH deployments deliver wire-speed bit rates

The GPON system-on-chip (SoC) solutions for fiber-to-the-home (FTTH) deployments include the PAS7401 GPON ONT, the MSP7162 GPON gateway, and the PAS5211 four-port GPON OLT. They feature GigaPASS architecture, which is already deployed in more than 6 million PON devices and is enhanced for WT-156 compliance. These devices include complete reference designs and software packages; all have proven interoperability with a wide-range of commercial GPON systems.

The 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 Wi-Fi. 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 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.

KEY FEATURES

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 quality of service (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 10Gbps port or four 2.5Gbps ports, 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. 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.
