120Gbps 1/10 Gigabit Ethernet StrataDNX® Qumran-UX Ethernet Switch Series

Currently Viewing:

Broadcom's BCM88270 Series, also known as the StrataDNX® Qumran-UX 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 BCM88270 devices process up to 120 Gbps traffic, supporting up to 28 full-duplex 1G Ethernet (GE) ports, 8 full-duplex 10GE ports or 2 full-duplex 40GE ports at Layer 2 through Layer 4 with integrated deep-buffer traffic management capabilities, and a fabric interface.
The BCM88270 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 Ethernet port rates.
