BCM88470

300Gbps 10/100 Gigabit Ethernet StrataDNX® Qumran-AX Ethernet Switch Series

Currently Viewing:

Broadcom's BCM88470 Series, also known as the StrataDNX® Qumran-AX switch series, can help build highly scalable, feature-rich, centralized, fixed or modular aggregation switches to enable cloud-scale networking and Carrier network applications. The BCM88470 devices process up to 300 Gbps traffic, supporting up to 48 full-duplex 10G Ethernet (GE) ports, 16 full-duplex 40GE ports, or 4 full-duplex 100GE ports at Layer 2 through Layer 4 with integrated deep-buffer traffic management capabilities, and a fabric interface.
The BCM88470 series is based on the seventh generation of the Dune scalable switching product line.
It is used to build a variety of network switch solutions with flexible I/O interfaces, such as Ethernet or OTN.

Features
