  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.

Features of  BCM5553x series

  • IEEE 802.3av, SIEPON P1904.1/D3.0, China Telecom 3.0, and Cable Labs® DPoE TM compliant
  • Simultaneous 10G symmetric and asymmetric operation with 1.25 Gbps/2.5 Gbps co-existence
  • 8x 10G IEEE 803.3av-compatible MACs with integrated 10G and 1G Burst-mode OLT SerDes
  • Supports up to 512 subscribers per 10G port with up to four classes of service per subscriber
  • Network Synchronization support for Mobile Backhaul over PON (1588 v2, ToD/1PPS, SyncE)
  • Support for extended-reach PON up to 100 km
  • Support for DOCSIS® Mediation Layer (DMLTM) middleware for Cable MSO applications

BCM55030: Multirate 10G/1G EPON Optical Network Unit With L3-Aware Switching And Traffic Management

Broadcom BCM55030 portfolio

  The BCM55030 is an IEEE 802.3av-compliant 10G-EPON ONU device supporting a 10G-EPON MAC, an integrated EPON SerDes, and four 10/100/1000 SGMII ports, all offered in an ultra low power and low-pin-count package.

Designed specifically to address the high-speed connectivity requirements of converging triple-play services (video-on-demand, HD-IPTV, voice over IP and high-speed Internet), together with 3G/4G mobile backhaul and business services, the 10 Gigabit per second (Gbps) BCM55030 SoC solution delivers ten times more bandwidth than current 1G EPON solutions.

  The BCM55030 supports both 10G and 1G upstream, so it can be used for both 10G/1G asymmetric and 10G/10G symmetric ONU designs. By leveraging Broadcom’s industry-leading support for multiple logical link identifiers per ONU and superior quality of service (QoS) feature set, the BCM55030 is capable of managing simultaneous transport of traffic from residences alongside mission-critical business services and cell tower backhaul services, all over a common infrastructure. This means time-sensitive mobile backhaul traffic and synchronization data may share the network with video, voice, and Internet data, without added delays, data loss, or QoS degradation, making it an ideal solution for OEMs and service providers serving dense urban areas.

Features of BCM55030

  • Delivers Broadcom’s highest EPON ONU integration, including a 10 Gbps media access controller, 10 Gbps EPON serializers/deserializers and forward error correction, a four-port Gigabit Ethernet switch, line rate packet classification and traffic management, and on-chip memory for both CPU and packet buffers, resulting in no external memory components.
  • The device is fully compliant with the new IEEE 802.3av 10G EPON standard including support for 10G EPON and 1G EPON co-existence on the same fiber. The chip supports both 10G/10G symmetric and 10G/1G asymmetric modes of operation The device supports Broadcom’s 2.5G TURBO-EPON® in addition to both standard 1G and 10G modes
  • Supports 16 logical links per chip, enabling the ONU to perform as if it were 16 independent ONUs, and providing consistent performance and service (Service Level Agreements) independent of network traffic and loading. Multiple logical links per ONU is a mandatory requirement in the CableLabs specification
  • Flexible support for reference clock, 1 PPS, and ToD transport, and system integration with Broadcom 1588v2 devices, provides an ideal solution for 3G and 4G mobile base station backhaul networks
  • Feature-rich firmware including IPTV support (IGMP v2/v3), IPv4/v6, VLANs, and QoS policy enforcement, enabling fast time to market of leading edge CPE solutions
