BCM5553x Family

High-Density 10G-EPON Optical Line Terminal Family

Currently Viewing:

The BCM5553x series allows OEMs to address telco and cable MSO 10G FTTx deployments with one silicon platform.
Broadcom’s BCM5553x series is a family of complete Systems on a Chip (SOCs) that deliver 10x bandwidth and higher subscriber count per fiber network. Designed to address high-speed connectivity and Quality of Service (QoS) requirements of residential triple-play services including Video on Demand (VoD), HD-IPTV, Voice over IP (VoIP) and high-speed Internet, the BCM5553x series of OLT SOCs delivers 10x more bandwidth. When combined with the BCM88350 family of integrated single-chip traffic manager/packet processors and the ultra-low-power, small-footprint BCM55030 Optical Network Unit (ONU) SoC, the BCM5553x 10G EPON Optical Line Terminal (OLT) family delivers a complete high-performance chipset platform.
