Unparalleled Integration Results in Twice the Density for Half the Cost and Half the Power

As the popularity of social networking, video on demand (VoD), and high bandwidth business services continue to climb, subscriber demand for higher-speed access networks is growing. Competitive pressures are upping the broadband ante - driving Telco and Cable providers to develop solutions that leverage existing networks and subscriber base to create profitable and differentiated services. Governments worldwide are making broadband a strategic initiative, investing in Fiber technologies such as Fiber to the Home/Business (FTTx). Analysts predict the number of worldwide FTTx subscribers to reach nearly one third of global wireline broadband subscriptions by 2016, driven largely by FTTx deployments in Asia.

With unparalleled integration, the BCM55524 Quad Port Ethernet Passive Optical Network (EPON) Optical Line Terminal (OLT) system-on-a-chip (SoC) combines the functionality of up to seven application-specific standard parts (ASSPs) and eliminates seven on-board memory devices, dramatically reducing system costs by up to 50 percent. Optimized to meet the bandwidth, scalability and performance demands of next-generation broadband access networks serving both business and residential subscribers, the BCM55524 delivers twice the density and half the power per port of its predecessor, the TK3723, the world's most widely adopted EPON OLT SoC.

Best in Class EPON and Carrier Ethernet Switching in a Total Solution

The BCM55524 quad OLT is designed to work in tandem with Broadcom's award-winning Strata XGS aggregation switches, combining feature-rich EPON and proven Carrier Ethernet performance in an end-to-end solution that meets the scalability, reliability, cost, and advanced feature set of next generation FTTx deployments. Backward compatibility with the TK3723 OLT allows system designers to leverage stable OLT software that has undergone extensive Carrier qualification and Interoperability (IOP) testing, thus providing a risk-free migration path for OEMs to higher density 16-port line card designs, while significantly reducing time-to-market and development costs.
