Broadcom Spins New EPON OLT System-On-Chip

Broadcom introduced its BCM55524 Quad Port Ethernet Passive Optical Network (EPON) Optical Line Terminal (OLT), packing twice the density and power per port of its existing EPON OLT system-on-a-chip (SoC). The new SoC combines the functionality of up to seven application-specific standard parts (ASSPs) and eliminates seven on-board memory devices, dramatically reducing system costs by up to 50 percent.


The BCM55524 quad OLT is designed to work in tandem with Broadcom's StrataXGS aggregation switch series and is backwards compatible with the existing TK3723 OLT chip. It offers four IEEE 802.3ah-compliant EPON MACs with Broadcom Turbo-EPON support as well as integration of four 1.25 Gbps/2.5 Gbps Burst-mode SerDes and four NNI-side SGMII SerDes. http://www.broadcom.com
