PMC-Sierra unveils first EPON ONU SoC with integrated OAFE technology
The PAS6500 devices are the first to integrate an EPON OAFE consisting of a burst mode laser driver, a limiting amplifier and a receiver control processor. By connecting to an on-board Bi-directional Optical Sub Assembly (BoSA) instead of an optical transceiver, the PAS6500 solutions reduce the cost, size and power of the ONU, while adding improved diagnostic capabilities.
The high level of integration, which also includes a VoIP processor, helps OEMs to reduce the cost of ONU equipment. All three devices feature PMC-Sierra’s field-proven GigaPASS architecturethat achieves sustained gigabit and greater data rates, and is already used in more than 15 million PON devices deployed worldwide.
PMC-Sierra’s PAS6500 family integrates a programmable networking engine that provides enhanced Quality of Service (QoS), complying with China Telecom specification version 2.1, including IPv6 protocol support. The unique power saving algorithms implemented within PAS6500 devices reduce ONU power consumption by up to 80 percent. This product family adds mobile backhaul over EPON support with the integration of Synchronous Ethernet and Time of Day delivery, wire-speed throughput at all packet sizes, queuing, filtering and advanced QoS. These solutions reuse PMC-Sierra’s widely-deployed EPON software packages and preserve field-proven interoperability in worldwide EPON deployments.
PMC-Sierra’s SFU and MDU reference designs are available for a range of user interfaces, including Gigabit Ethernet, Fast Ethernet and POTS. The reference designs reduce the cost and increase the energy efficiency of EPON networks. These solutions offer a complete EPON ONU software package, which is compatible with the PAS6301 software and supports low footprint OS and Linux featuring an EPON protocol stack and networking drivers, IEEE 802.3ah OAM protocol, including operator-specific stacks, integrated peripheral drivers and a complete VoIP software solution.
Availability
The PAS6500 samples and reference designs are available now to select customers.
