The FALC ON-S developed by the German networking chip designer is a complete GPON Optical Network Unit (ONU) system-on-chip in a compact 11 x 11 mm package for Small Form-factor Pluggable (SFP) modules with fully integrated GPON Optical Network Unit functionality. The chipset enables a simple upgrade to GPON backhauling for a variety of broadband access systems like MDUs and WAN-agnostic gateways.
The FALC ON-S small form factor and very low power consumption that exceeds the European Code of Conduct requirements for years 2013 and 2014 also make it an ideal solution for the emerging small cell wireless architectures.
As the industry’s first fully standard-compliant GPON SoC with integrated laser driver and limiting amplifier, the integration of key optical components and control circuitry optimizes board space and reduces total system’s Bill of Material (BOM) cost. Direct control of the on-chip laser driver, including idle mode, significantly reduces power consumption and the built-in hardware-based Rogue ONU management gives reliable isolation of disturbing ONUs and efficient protection of data services.
Applications supported include compact MDU cabinets in both pure fiber and mixed fiber/xDSL configurations, fiber backhaul of cellular base stations including small cells and customer premise equipment (CPE) with SFP socket, providing the flexibility to use one home gateway design to support FTTH, xDSL or other network technologies.
Infonetics Research predicts continued rapid growth in the global GPON market. Analyst Jeff Heynen reports that GPON ONT port shipments totaled about 17.5 million in 2012, up 127% from 2011, and he forecasts GPON ONT ports to further grow to 26.8 million by 2016.
“With continued expansion of fiber networks worldwide and the accelerating transition from EPON to GPON to provide better performance and QoS, broadband access vendors offering equipment with SFP connectivity can easily upgrade to GPON now," said Dirk Wieberneit, Lantiq Senior Vice President and General Manager of the Customer Premises Equipment (CPE) Business Unit.
FALC ON-S devices are available now for engineering development. Volume shipments will start in Q2 2013.
