Passave Adds GPON Chipset to FTTH Portfolio

Passave introduced a pair of Gigabit Passive Optical Network (GPON) devices, the PAS5211 optical line terminal (OLT) and the PAS6211 optical network terminal (ONT), bps for GPON-compatible FTTH equipment. The new devices use Passave's GigaPASS architecture, providing interoperability for GPON central-office (CO) equipment and GPON customer premise equipment (CPE).

Passave said developing a low-cost, high-performance GPON FTTH semiconductor is a significant technical challenge because it requires single-chip integration of gigabit and faster point-to-multipoint Passive Optical Network (PON) transmission topologies at a price-point suitable for consumer premise equipment such as access modems. Its GigaPASS architecture delivers gigabit and higher transmission rates, provides wire speed protocol processing, and supports mixed-mode PON traffic.

Key features of Passave's new GigaPASS-based GPON devices under development include:

  • GigaPASS architecture for wire speed performance at 2.5 Gbps downstream and 1.25 Gbps upstream

  • An embedded, high-performance processor running Linux and VxWorks

  • Forward error correction -- Passave said this enables carriers to double the reach or number of customers that the network can support

  • AES-128 encryption

  • FSAN ITU-T G.984 standard compliance

Commercial availability is expected in in 2006. Pricing for the PAS5211 OLT starts at $300 and for the PAS6211 ONT pricing starts at $30 in 10,000-piece quantities.
