description: This topic is devoted to the study of the possibility of using SFP ONU for upgrading FTTB networks with switching access switches to GPON networks. And determining the optimal schemes for connecting FTTB switches to the GPON tree. Purpose: to investigate how to connect an access switch to an existing PON tree with GPON subscribers. This can be an existing port with PON subscribers, or they should be connected to a separate port on the line card. Task: calculate the maximum traffic per subscriber for IPTV and Internet services. Analyze how and how many switches can be connected. Conduct laboratory tests on the ability of the switch to work when connected to the PON tree in a mixed mode with other GPON subscribers. To make a conclusion about the feasibility of switching from the FTTB technology to the updated connection scheme via the SFP ONU module. The data for calculating the network load was taken from the analysis of the traffic of actually connected subscribers. The work was carried out at the Rostelecom company, where the necessary equipment for testing was provided: a traffic generator, ONT of various models, a Laptop, OLT. Switch, SFP ONU. As a result, the FTTB and GPON technologies, their connection structures, and the equipment used were analyzed. The maximum load traffic was calculated for the full number of connected subscribers. Tests were carried out on the possibility of connecting the access controller to the GPON network and its stable operation together with the rest of the GPON subscribers. We also tested the maximum throughput of the provided SFP ONU in both directions of the data flow. In the end, conclusions were drawn about the possibility of re-connecting subscribers using FTTB technology on the PON tree, without changing the configuration of devices on the subscriber's side.
