The PON network consists of OLT, ODN and ONU. OLT belongs to the service node side of the access network and is connected to the corresponding service node equipment through SNI interface to complete the service access of the access network. In the PON technology application, OLT equipment is an important local-end dev. In order to facilitate a clearer understanding, we provide examples of manufacturers' equipment for a detailed explanation.OLT usually consists of the following parts: 1. Control board (also called the main control board or super control unit) generally an OLT has a main board and a backup board. 2. DC power supply board (from the negative 48 volts of the switching power supply to the power supply) is also generally 2 boardsof themain and backup. 3. Fan unit (the main. In OLT deployment, different access strategies should be selected according to different service types, customer needs (long term goals) and regions, etc. 1.
