Thanks to small dimensions of device and 1U size, V5824G could be assembled in every rack. At the beginning of installation, 1:8 splitters with attenuator were used because the high level of optical power could damage the receivers due to low distance to pump station (12km). Having used OLT device, the ONT profiles has been created. Therefore, it’s important to note that instead of classic ONU devices the GPON Stick was used. This is a really small ONT device in transceiver form, which complies with industry requirements (range of temperature, voltage, humidity). GPON Stick could be inserted in for instance industry converter, so then this converter would be the GPON end device.
The pump station, which was connected through GPON with sewage farm control was controlled by SPS (Surface Pump Systems). The real speed of transmission of SPS data was slow comparing with other application of GPON technology, however still very significant. That is was why SPS unit constantly checks the availability of station and alarms if one of them does not respond within a few seconds.
The GPON implementation encompasses: the monitoring of the pump station control, the water level from raining pools, the amount of provided and siphoned off water – this kind of information was through fibers transmitted to Controlling Municipal Services Department Centre in Dillingen to process, control, record and archive. The using of GPON technology lets Municipal Services Department in Dillingen-Lauingen minimalize the costs of connection and the selection of Dasan devices causes the high level of reliability of installed system.
