FBT Splitter and PLC Splitter
A splitter is a component of a PON network and is a passive device that connects the OLT to the ONU. Its function is to distribute downlink data and concentrate uplink data. The splitter has one uplink optical interface and several downlink optical interfaces. The optical signals coming from the uplink optical interface are distributed to all downlink optical interfaces for transmission, and the optical signals coming from the downlink optical interface are aggregated to the only uplink optical interface for transmission. Only when the optical signal is transferred from the uplink optical interface to the downlink optical interface, the optical signal strength/optical power will decrease, and the same applies when transferring from the downlink optical interface to the uplink optical interface. The strength of the optical signal can be the same or different from one downlink optical interface to another. Splitter principle of operation In single-mode optical fibres conducting optical s...
