PMC-Sierra Introduces Analog Front End Devices for GPON and EPON Fiber-To-The-Home Central Office Equipment.

SANTA CLARA, Calif. -- New AFEs Will Lower Cost of Passive Optical Network Deployments in Global Markets

PMC-Sierra, Inc. (Nasdaq:PMCS) today announced the availability of four new Analog Front End Devices (AFEs) for GPON and EPON FTTH equipment. These new Physical layer devices will compliment PMC-Sierra's line of networking SoCs for GPON and EPON systems, creating the industry's most complete FTTH product portfolio. Using these new Physical layer devices, system and sub-system OEMs will be able to lower the cost of GPON and EPON access network equipment that delivers carrier-grade triple-play services -- voice, data and IPTV -- to consumers worldwide. According to a recent report from CIR, a leading industry analyst firm, the component and module market for FTTx networks is estimated to grow from approximately $630 million in 2006 to more than $1.5 billion by 2011.

"The introduction of these new devices demonstrates PMC-Sierra's commitment to providing a complete family of products for both GPON and EPON FTTH deployments," said Victor Vaisleib, general manager of the FTTH Business Unit at PMC-Sierra. "They will enable system OEMs to produce higher-performance systems for IEEE802.3ah EPON, which is widely deployed in Asia, and ITU-T G.984 GPON, which is increasingly popular in North America. PMC-Sierra is the only company with a complete set of AFEs and networking SoCs for both PON standards. In particular, our GPON AFEs significantly exceed the ITU specifications for burst acquisition timing, sensitivity and dynamic range, and include a built-in diagnostic function, providing for a more robust, yet lower-cost solution than those previously available."

The new GPON devices include the PAS7351 GPON Trans-Impedance Amplifier (TIA) and the PAS7361 GPON Limiting Amplifier (LIA), that together form a Gigabit PON Optical Line Terminal (OLT) burst receiver for use in ITU-T G.984 GPON transceivers (see Figure 1). A GPON transceiver based on the PAS7351/PAS7361 can surpass the requirements for GPON low power and high power Class B+ burst-mode applications, enable a 64-user split ratio at low signal-to-noise environments, and increase network design flexibility. The devices can provide a signal sensitivity of -33 dBm with a dynamic range of more than 26 dBm. Acquisition time can be as low as 24 bits. Both of these devices support PIN and avalanche photodiode (APD) receiver applications and include embedded PON diagnostics functions. The devices use a single 3.3V power supply and provide for LVCML differential output, either AC- or DC-coupled with direct photodiode input.

The new EPON devices include the PAS5351 EPON Trans-Impedance Amplifier (TIA) and the PAS5361 EPON Limiting Amplifier (LIA). Together they form a Gigabit Ethernet PON Optical Line Terminal (OLT) burst receiver that exceeds the IEEE802.3ah Ethernet in the First Mile EPON transceiver standard (see Figure 2).

"Compared with EPON, GPON systems have greater timing sensitivities that require high performance PHY devices," said Jag Bolaria, senior industry analyst with The Linley Group. "PMC is the first major company to support both GPON and EPON standards, with these high performance PHYs and a broad product line that includes SoC devices for both Central Office and Customer Premise Equipment."
