The BCM54880B0KFB from Broadcom is a high-performance 8-port Gigabit Ethernet transceiver that combines eight 10/100/1000BASE-T and BroadR-Reach™ PHYs on a single, power-efficient 65 nm CMOS chip. It’s designed for compact, high-density networking equipment, offering extended cable reach, low power consumption, and full IEEE Ethernet compliance in one integrated solution.
As part of Broadcom’s BroadR-Reach™ family, this transceiver extends Ethernet connectivity far beyond standard limits. It supports data transmission over both twisted-pair and coaxial cables for distances of up to 1,000 meters, depending on the cable type and quality.
This makes it an excellent choice for switches, broadband access systems, and industrial IP networks that need dependable, high-speed connections across larger areas.
Let’s take a closer look at what makes this 8-port transceiver a reliable choice for modern Ethernet infrastructure.
