GPON Uplink 

The GPON system is a single-fiber bidirectional system. It uses wavelengths 1310 nm in TDMA mode in the upstream direction and wavelengths 1490 nm in broadcast mode in the downstream direction. Maximum downstream rate at the GPON physical layer is 2.488 Gbit/s, maximum upstream rate at the GPON physical layer is 1.244 Gbit/s.

Supports a maximum logical distance of 60 km and a physical distance of 20 km between theremotest ONT and nearest ONT, which are defined in ITU-T G.984.1. Supports a maximum of eight T-CONTs. Supports T-CONT types Type1 to Type5. One T-CONT supports multiple GEM ports (maximum of 32 GEM ports are supported).Supports three authentication modes: by SN, by password, and by SN+password
