Also known as an optical splitterSplitter Also known as an optical splitter, this is a passive device (i.e. not requiring a power supply) used in PON technology to sort and combine light wave energy. A splitter replicates the optical signal from one fibre to a predefined number of other fibres (splitter 1 to 8, 1 to 4 and so on) and combines the optical signals from the different clients., this is a passive device (i.e. not requiring a power supply) used in PONPON PON stands for Passive Optical Network, which describes all types of optical networks that have no active equipment between the start and end point. One of these is the network used to bring the fibre-optic link to the end-user by means of point-to-multipoint architecture in which a single fibre is used to reach several recipients via non-powered optical splitters. technology to sort and combine light wave energy.
