BCM88476

High-Density 10 Gigabit Ethernet StrataDNX® Kalia Ethernet Switch Series

Currently Viewing:

Broadcom's BCM88476 Series, also known as the StrataDNX® Kalia switch series, can help build highly scalable, feature-rich, Modular Chassis or aggregation switches to enable cloud-scale networking and Carrier network applications. The BCM88476 devices process up to 300 Gbps traffic, supporting up to 32 full-duplex 10G Ethernet (GE) ports, or 8 full-duplex 40GE ports, at Layer 2 through Layer 4 with integrated deep-buffer traffic management capabilities, and a fabric interface.
The BCM88476 series is based on the seventh generation of the Dune scalable switching product line. Together with the BCM88770 fabric element (FE) device and the BCM88670/88680 fabric access processor (FAP) devices, it is used to build a variety of network switch solutions:
• Over 100 Tbps core/edge switch with single-stage fabric for data center, packet transport, or carrier network applications
• Multiple interconnected chassis of different capacities that use BCM88680, BCM88476 and BCM88770 fabric to create a scalable core platform, delivering up to 9,000 ports of 100GbE or their 40GbE/10GbE equivalents
