Broadcom BCM5315x Series Ultra-Low Power GE Switches

Broadcom BCM5315x Series Ultra-Low Power GE Switches featuring 10GE Uplink Ports are optimally designed for low-power SMB, enterprise, service provider, and industrial applications that rapidly transition to gigabit-ethernet connectivity and beyond. These highly integrated Ethernet Switches are designed using the 28nm RoboSwitch™ architecture and include models with 10 and 11 ports that support 100M/1GE/2.5GE and 10GE speeds.

The BCM5315x are ideal for low-power applications that include unmanaged and web-managed SMB switches, port-extender (PE) enterprise switches, enterprise routers, and security appliances, next-generation industrial solutions with Time-Sensitive Network (TSN) support and service provider access equipment. The BCM5315x Series is supported by a multitude of software suites for different operational modes.
