Your guide to ordering fibre optic PLC splitters

An introduction to fibre optic PLC splitters

Planar Lightwave Circuit Splitters (commonly known as PLC splitters) are a modern technology used to separate or combine optical signals. They divide one or two light beams of data into multiple, or vice versa, and are generally used to provide a low-cost light distribution solution for applications where larger split configurations are required. These applications include Passive Optical Networks (PON), such as EPON, GPON and FTTx. PLC splitters are widely installed between the OLT and ONT in the network.


Different types of PLC splitters

Splitters are categorised by the PLC splitter chip they use. Customers can choose different input and output numbers depending on subscriber conditions / cable length. TXO Optics are flexible and can offer different packages to meet client’s needs. Packages range from small size PLC splitters that are used in small terminal boxes, all the way through to big size rack mounted PLC that can be installed in racks.


PLC splitters available from TXO Optics include:

Bare fibre: Bare fibre optic splitters are generally used in PON networks. They can be spliced freely according to the applications and require the least space during cabling by being installed in the pigtail cassette, test instrument and WDM system.

Blockless: Blockless splitters have a stronger fibre protection than bare fibre. Their main use is in various connection and distribution boxes or network cabinets.

Fanout: Fanout splitters add a length of ribbon fibre terminated with fanout kit behind the PLC split chip.

Your guide to ordering fibre optic PLC splitters

To assure you’re getting the right product for your needs, it is helpful if you can answer the following questions:

  • What split ratio do you require? Common ratios: 1×2, 1×4, 1×8, 1×16, 1×32, 1×64, 2×2, 2×4, 2×8, 2×16, 2×32, 2×64
  • Would you like the PLC splitter to have connectors? The most common types include: ST, LC, FC and SC
  • Do you need the PLC splitter to be ABS box, steel tube or the insert-type package?
