Classification and use of PLC optical splitter

Planar waveguide optical splitter (PLC Splitter) is an integrated waveguide optical power distribution device based on a quartz substrate, which is suitable for connecting central office and terminal equipment in passive optical networks (EPON, BPON, GPON, etc.) and FTTx networks. Realize the branching of optical signal.

It is one of the important passive optical components in fiber optic links, with one or more input ports and multiple output ports. Its three most important components are the input end, output end and chip of the optical fiber array. The design and assembly of these three components play an important role in whether the PLC optical splitter can work stably and normally.

Classification and specific usage of PLC optical splitter:

First of all, let’s first understand that there are two types of PLC optical splitters: centralized distribution and cascade distribution. Next, let’s talk about classification and usage .

【1】Bare fiber type

The bare fiber PLC optical splitter is directly led out by optical fiber (generally ribbon optical fiber), and the two ends are not terminated. It is mainly suitable for occasions that are not frequently disassembled. It is installed in various types of pigtail boxes by welding or cold splicing. or test instrumentation.


Micro PLC refers to a small optical splitter assembly that is packaged in steel pipe and uses a 0.9mm loose tube for fiber output. It is mainly suitable for tight installation space and does not need to be welded or cold spliced, such as optical cable splicing boxes, optical fiber splitting boxes, and can also be installed in plug-in and rack-mounted optical splitter combination boxes.

【3】ABS cassette

It is packaged in an ABS plastic box, and the port is led out by a pigtail. It is mainly used in the rack, and installed in the optical cable transfer box when the optical fiber branch enters the home.

【4】Insert type

The plug-in PLC is packaged in an ABS plastic box, and the port is end-type. It is used for the user access point that needs to be split in the FTTX system. Its main function is to complete the termination of the optical cable entering the community or building. It has the functions of fixing, stripping, welding, jumper, and splitting the optical fiber. form into the end user.

【5】Rack mount

Passive PLC filter, rack-mounted, PLC split, 1×32 standard split (equal split), SC-APC connector Rack-mounted PLC is packaged in a metal box and can be installed in a 19-inch 1U cabinet.
