The FiberTechnic® FD16XX GPON OLT (Optical Line Terminal) is the main unit of fiber optic PON network. PON (Passive Optical Network) is a single-fiber bidirectional optical access network with a point to multipoint (P2MP) structure with a typical tree-type topology. The system consists of OLT (Optical Line Terminal), ONU (Optical Network Unit), and ODN (Optical Distribution Network) which provides a transmission channel.
FiberTechnic® FD16XX OLT GPON device meets the ITU G.984/G.988 standard and provides downstream 2.5 Gbps and upstream 1.25 Gbps. In downlink direction (OLT to ONU), the signal sent by the OLT reaches each ONU through the ODN. While, in uplink direction (from ONU to OLT), the signal sent by the ONU reaches only the OLT, not other ONUs. To avoid data conflict and improve network efficiency, the uplink direction adopts TDMA mode and manages the data transmission of each ONU. ODN provides an optical channel between OLT and ONU.
Fibertechnic’s FD16XX GPON OLT has several versions in which the system supports up to 2048 GPON ONU terminals. The devices offer the possibility of connecting a 2x10Gb UPLINK, which increases the efficiency and competitiveness of the operator’s network. The OLT terminals have two types of power supply, AC 230V and DC 48V.
