The fiber optic splitter, optical coupler, also known as beam splitter, is a passive optical device that can split an imput optical signal on a fiber cable into multiple output signals at a certain splitting ratio. The fibre optical splitter is a key component in passive optical network(PON), especially widely used in GPON FTTH (fiber to the home), FTTC (fiber to the cabinet), and FTTB (fiber to the building) solutions.
Various packaging types including bare fiber type, mini steel tube type, ABS box type, cassette insertion type, tray type, and rack-mounted type can be chosen.
Classified by manufacturing technique, there are two commonly used types of optical splitters:
✔ Planar Lightwave Circuit Splitter (PLC Optical Splitter)
✔ Fused Biconical Taper Splitter (FBT Optical Splitter )
✔ Planar Lightwave Circuit Splitter (PLC Optical Splitter)
Planar Lightwave Circuit (PLC) splitter is a passive optical device based on based on planar lightwave circuit technology, which is available in a variety of split ratios. A typical PLC splitter consists of a PLC chip and an array of inputs and outputs, the number of which depends on the splitting ratio.

A typical PLC splitter consists of a PLC chip and an array of inputs and outputs, the number of which depends on the splitting ratio.
It also known as mini plc splitter, micro plc splitter or blockless plc splitter. The mini PLC splitter is very similar to the bare fiber splitter, while the former doesn't need fiber optic fusion during installation. This steel tube splitters are commonly used in fiber optic distribution box(ODB), optical patch panel and fiber joint splice closure.
The ABS splitter is packed by a ABS box, which has a solid protection for internal optical components and fiber cables. It is universally used in fiber optical terminal boxes for GPON FTTx Solutions.
Also called insert type splitter, insertion cassette splitter, it is packaged With mini plug-in style, it can be installed in the cassette splitter distribution box and splice cabinet.
The Rack Mounted PLC Splitters consist of the PLC splitters and the metal enclosure. Well-packaged in a 19-inch rack mount panel, the rack PLC splitters suit for the indoor or outdoor applications in FTTx projects, CATV or data communication centers.
Bare Fiber PLC Splitter
There is no fiber optic connectors terminated on the bare fiber PLC splitter ends. That's to say all ends of this splitter is bare fiber, which is easily spliced and takes the least space while reducing installation costs. It is widely installed informal splice boxes and splice boxes in passive optical networks.
Tray Type PLC Splitter
The Tray type PLC splitters are widely installed in ODF racks, standard network cabinets, standard integrated cabinets and other series of products. Bare fiber type /steel tube type /box type optical splitter can be installed in the tray and flexibly configured as required.
(Ps. Fiber optic splitter box is usually used with 2mm or 3mm outer diameter cable, while the other is normally used in combination with 0.9mm outer diameter cables.)

A fiber optic splitter also called an optical splitter, is a passive power distribution device that can split or divide a light beam into multiple light beams by a certain ratio. The optical splitter plays a crucial role in the passive optic network (PON) systems, like GPON, FTTH, FTTB, FTTC, etc.
The device contains multiple input and output ends. Whenever the fiber beam transmission in a network needs to be divided, fiber optic splitter can be implemented for the convenience of network interconnections. As one of the most important passive devices in the optical fiber link, the optical splitter, an optical fiber tandem device with many input and output terminals, plays a crucial role in the optic network systems to connect the main distribution frame and the terminal equipment and to branch the optical signal.
A fiber optic splitter is a passive optical contrivance, generally, the basic working principle of the optical splitter is to distribute or split a light signal into two or more light signals by a certain ratio through the fiber.
When the light transmits signals in a single-mode fiber, its energy can’t entirely concentrated in the fiber core, thus a small amount of energy can be spread via the cladding of fiber. In other words, if two optical fibers are close enough, the transmitting light in an optical fiber can enter into another fiber, which make the reallocation technique of fiber signal achieved in multi fibers.
There are two types of optical splitter, PLC splitter and FBT splitter, so there are two ways of working modes. PLC splitter is based on planar lightwave circuit technology, and it’s composed of an optical splitter chip and an optical fiber array at both ends. The splitter chip is the core that can divide one incoming signal into multiple output signals.
While FBT splitter, or coupler, is two or more fibers are joined together by melting using fusion technology. The changes of the splitting ratio are monitored in real-time. Once the splitting ratio achieves the requirements, the taper process will end. The input port is one fiber, and the multi-outputs are in the other side.
PLC means Planar Lightwave Circuit. It's a planar arrangement of waveguides on a substrate, which is widely used in fiber optical networks. The PLC splitter is of uniform splitting ratio with high reliability.
FBT also called Fused Bicnoic Taper, is a traditional and mature technology to weld several fibers together closely. The FBT splitter is protected by a steel tube or an ABS module because the fused fibers are very fragile.
Kindly check the differences listed below:

● Wide range of operating wavelength (1260nm~1650nm)
● Simple and easy installation for a variety of fiber optic distribution box, distribution frame and fiber optic cabinets.
A qualified PLC splitter should be compliant with The GR-1209 standard. There are 5 main factors that determine the quality, they are optical bandpass, insertion loss, return loss, uniformity & directivity.
The insertion loss can be tested by a power meter and the reference power level can be obtained when measuring all the outputs of the splitter. In a similar manner, we can use a return loss meter to test the return loss. The way is to connect the return loss meter with the input port of the splitter and combine the outputs to a non-reflective index matching gel.
The directivity of the splitter can be measured and the way is similar to the insertion loss test. While the power meter and light source are connected to each of the input ports of two output ports.
The maximum allowable insertion loss can be calculated by the following formula:
1×N Optical Splitter | 0.8 + 3.4 log2N |
2×N Optical Splitter | 1.0 + 3.4 log2N |
(Note: "N" refers to the number of output ports.)
Here offer you the insertion loss reference table for these 2 types of splitters.
