Introduction
Planar lightwave circuit (PLC) splitter is a type of optical power management device that is fabricated using silica optical waveguide technology to distribute optical signals from Central Office (CO) to multiple premise locations.
PLC splitters are commonly found in PON(Passive Optical Networks), Datacom, LAN(Local Area Networks), CATV(Cable TV), LCP(Local Convergence Points), FTTx, and more applications, suitable for communication, medical, bank, building, large Office buildings, offices and other places with high-quality network requirements.
Blockless PLC splitter is mainly used for the connection of outdoor optical distribution boxes or network cabinets, aiming to improve the utilization rate of customer ports.
Application
In passive optical networks, PLC splitters are usually installed between an Optical Line Terminal (OLT) and an Optical Network Unit (ONU) or Optical Network Terminal (ONT) near the end user. The input end of the PLC splitter is connected with the optical fiber link of the OLT in the central office (CO), and multiple optical signals are split and transmitted to the end users of the optical network.
The PLC optical splitter can realize optical signal splitting in two ways: centralized distribution and cascaded distribution. Centralized distribution means that the PLC optical splitter is centrally installed at a certain position between the optical line terminal (OLT) and the optical network unit (ONT), centrally performs optical splitting processing on the signal at the central office and then transmits it to each end user.
At this time, the central office often uses a 1x32 or 1x64 PLC optical splitter. Different from the centralized distribution, the PLC splitters in the cascade distribution are distributed more and scattered, and the structure is complex. In this structure, there is both primary and secondary splitting. Normally, a 1x4 PLC splitter (connected to the OLT port) is used for the first-level split, and a 1x8 PLC splitter (connected to an external terminal) is used for the second-level split.
