Comparison of ZTE C300 Series Boards

Comparison-of-ZTE-C300-Series-Boards

ZTE’s ZXA10 C300 series solution is very threatening to competitors in the global FTTP market. The new ZXA10 C300 platform is one of only a handful of FTTP OLT solutions that supports both standards-based GPON and EPON, not to mention point-to-point active Ethernet (AE) FTTP and 10G EPON. This gives ZTE a solid competitive advantage in terms of deployment flexibility vis-à-vis rival vendor OLTs, most of which will support only one or two of the various FTTP connectivity options. This article will introduce you ZTE C300 series boards.

 

Switching and Control Cards

 

The ZXA10 C300/C350/C320 supports the following switching and control cards:

  • SCTM: supports 2.56 Tbps switching capacity, 256k MAC address table.
  • SCXN: supports 480 Gbps switching capacity, 32k MAC address table, and VoIP function (with VoIP daughter-card).
  • SCXM: supports 480 Gbps switching capacity and 32k MAC address table.
  • SCXL: supports 800 Gbps switching capacity and 32k MAC address table.

SMXA: supports 128 Gbps switching capacity, 32k MAC address table.
