GPON OLT Testing
The passive component in the GPON – the optical splitter – is actually bi-directional: It divides the downstream signal from the OLT to the ONUs/ONTs and combines the upstream signals from the ONUs/ONTs into one signal, which is sent to the OLT. The splitter is therefore sometimes called a splitter/coupler. As there are no amplifiers inside the optical part of the network a GPON with N ONUs/ONTs will ideally send 1/Nth of the optical power from the OLT to each ONU/ONT – in reality they will receive less than that due to loss in the splitter and the optical fibers. As there has to be sufficient signal for the ONU/ONT to detect the signals this limits the number of ONUs/ONTs in the GPON as well as the reach of the GPON.
The Internationally certified Saturn OLT meeting the requirements of ITU-T G.984/G.988 with carrier-class reliability and complete set of security functions. this product is designed with focus on quality performance and features. Based on advanced technology and supporting powerful Ethernet services and QoS features, the Saturn OLT runs highly flexible software in order to satisfy custom operator requirements.
The PON and GPON market will grow in the coming years driven by the increasing number of internet based applications used by private and small business internet customers and the wide spread use of smart phones. In a market research report Radiant Insights estimates the PON market to grow at a CAGR of 3.6% until 2018 with GPON having a larger market share and growth than another PON technology – the Ethernet Passive Optical Network (EPON). In another report Global Industry Analysts projects the global GPON market to reach US$10.5 billion by 2020 with Asia Pacific being the largest market.
