Xponent Announces GPON Triplexer Reference Design

Discrete Transceiver Reference Design Demonstrates Leading Triplexer Component Performance and Shortens Customers' Time-to-Market

MONROVIA, CA -- (MARKET WIRE) -- October 3, 2005 -- Xponent Photonics, the leading innovator of FTTx optical components, today announced the availability of a reference design transceiver for GPON ONU/ONT applications. The reference design meets demanding specifications for analog video receiver performance including:

--  50 to 870 MHz bandwidth
--  48 dB CNR or better
--  Wide dynamic range  of -6 to +2 dBm
--  16 dBmV/ch RF output
    
The digital transmitter section supports rates of 155 Mbps, 622Mbps, 1.24 Gbps and 2.48 Gbps with output power capability from -4 to +4 dBm. The digital receiver designs support downstream rates of 2.48 Mbps with -25dBm typical Sensitivity, 1.24 Mbps with -29 typical Sensitivity and 622 Mbps with -32 dBm typical Sensitivity.

Xponent offers royalty-free use of its discrete reference design transceiver to transceiver and system vendor customers of its triplexer and diplexer optical blocks. Xponent's discrete reference designs help customers to reduce their engineering investment and time-to-market for FTTx transceivers, subsystems and systems. The new triplexer reference design utilizes off-the-shelf variable rate ICs that are suitable for standard BPON applications (622 Mbps downstream/155 Mbps upstream) and GEPON applications (1.24 Gbps upstream/ 1.24 Gbps downstream) in addition to GPON applications (up to 2.5 Gbps downstream/ 2.5 Gbps upstream).

Xponent's discrete reference design support for optical block customers includes:

--  Schematic and Gerber files
--  Detailed BoM
--  Sample Boards with complete test data sheets
--  Manufacturing application support for two methods of low-cost PCB
    attach of Xponent optical blocks to PCB: 1) via flex-circuit leads with
    packaged optical block or 2)via wire bonding from contact pads on the
    unpackaged PLC optical block directly to the PCB.
