The BCM56520B0KFSBG is Broadcom’s seventh generation of the StrataXGS® product line. It is a highly integrated multilayer switch designed to address new and emerging Enterprise and Metro Area Networking applications. With a combination of cost-optimized Ethernet functionality, sophisticated classification, accounting, and Metro protocols, and advanced services, the BCM56520B0KFSBG makes an ideal solution for the Enterprise wiring closet as well as Metro fixed access and edge networks.
The BCM56520B0KFSBG incorporates up to 24 ports of GbE and four ports of HiGig2™. The four ports of HiGig2 can operate as standard IEEE 802.3ae XAUI™ or as ports running the HiGig2 protocol. Using the HiGig2 protocol, the BCM56520B0KFSBG can interconnect with other Broadcom devices for scalable, high-performance fixed, and modular systems. Building upon the industry-leading XGS architecture, the BCM56520B0KFSBG is the industry’s first true unified wireless/wireline switch. Supporting the CAPWAP protocol for access point and mobility domain connectivity, the BCM56520B0KFSBG enables edge stackable systems to offer the performance and scalability previously only available on high-end wireless controllers. With this new paradigm, system vendors can deliver a seamless, integrated wireless solution with a dramatic reduction in total solution cost.
