ZTE GTBO Overview:
ZTE GTBO Service Board is an 8-port XGPON OLT interface board, which cooperates with ONU to realize GPON access service for ZTE C320 C300. ZXA10 C320 is new-generation compact OLT, only 2U high, saving installation space; high line card density: industry-leading 16-port GPON/EPON and 48-channel P2P board capability, single-frame can provide 32 G/EPON ports and 96 channels P2P GE port. ZTE ZXA10 C300 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.
