Applications of Different Package Type PLC Splitters

Applications of Different Package Type PLC Splitters

As one of the most important component of PON (Passive Optical Network) system. The market of fiber optic splitters has grown rapidly. The most commonly used type of fiber optic splitters are FBT (Fused Biconical Taper) coupler splitter and PLC (Planar Lightwave Circuit) splitters. But with the maturity and development of the splitter producing process, the cost of PLC splitter is close to FBT splitter’s. Thus, people are more prefered to use PLC splitters instead of FBT splitters because of the better performance of PLC splitters. In today’s market, there are many package type of PLC splitters which are designed for different applications. Today, we talk about something about the package type of PLC splitters.


If you are the newbie and first time to buy PLC splitters, you might be curious about the package type of the splitters. Actually, it is not as complex as you think. At present, there are six major package type of PLC splitters according to different applications, i.e. bare fiber splitter, module splitter, rack-mount splitter, fan-out & blockless splitter, Tray splitter and LGX splitter. Of course, these five types are the basic type and there are upgrade version on their foundation offered by different vendors. For example, the following shows us the PLC splitters of Fiberstore with different package types.

  • Bare fiber optical splitter
  • ABS splitters
  • Blockless fiber splitter
  • Fanout splitter
  • Tray splitter
  • Rack-mount splitter
  • LGX splitters
  • PLC splitter in mini plug-in type

The bare fiber splitter is a type of splitters without connectors. Its input and output are designed with bare fibers (generally use ribbon fiber to output). Bare fiber splitters are used for small spaces that can be easily placed in a formal joint boxes and splice closure. In order to facilitate welding, it does not need specially designed for space reserved.


Module splitter, also called cassette splitter, is designed with direct 2.0nm or 3.0nm fiber output. This type of splitter is usually used for patch panel use, such as network cabinet and optical distribution box. It does also need to splice and can better protect the fiber when using. The typical type of module splitter is with ABS box package.


Rack-mount splitter is splitter designed in 19 rack mount metal box. In general, it is with fiber optic adapter in the front panel. Rack-mount splitter is used in 19″ ODF (Optical Distribution Frame).

Blockless fiber splitter and Fan-out splitter are generally called Mini fiber splitter. The former is designed as direct 900μm buffered fiber output pigtail. The latter is designed with 900μm buffered fiber input and fan-out output which can support higher split ratio. They can both be used in splice closure, optical distribution box, as well as installing in tray and rack-mount splitter box to form the tray splitters or rack-mount splitters. Their advantage is that we have no need to splice.

In tray splitter, input fibers and output fibers are preinstalled on a tray which easily fit within ODF, the Cross Connection Cabinet and other optical fiber distribution equipment. The splitters are secured within the trays and the trays are tamper-proof to prevent unwanted entry.


LGX splitter is design in a LGX module which is used for LGX chassis application. It is also terminated with adapters and according to different requirements, LGX modules can be inserted into the chassis. In addition, LGX splitter can also installed in rack mount chassis.


There’s no one-size-fits-all solution. Thus, so many pacakge type of PLC splitters have been launched to the market to satisfy all kinds of application requirements. Fiberstore offers a comprehensive solution of fiber optic splitters. If you have any requirement of splitter or other components related to PON systems, please visit

Advancement of technology answered many difficult queries inside a second. Multiplexer and demultiplexer (Mux Demux) may be the one that is a sophisticated creation that can help in transferring the data extremely fast. There are lots of sites that may be browsed and also the gradel quality of Mux Demux solutions is obtained that suit with all the network hardware brands. All these products are available with a good warranty and therefore are very much reliable products. An individual can mail if the product is required and then order for the same.

Mux Demux is the device that will help within the selection of most of the analog or even the signals from the digital inputs and these are then forwarded and single lines are obtained. Multiplexer will enable many signals that combine particular resource or equipment. This helps in minimizing one device per input signal to one informing line. A multiplexer that has double inputs has many select lines that will select the kind of line that holds the input pins and forward it to the pins from the output side lines. The job of the multiplexers is to make the level of data to higher amount and is passed across the network in a with time and the bandwidth.

The demultiplexer or even the double multiplexer may be the device that will absorb the one particular signaling which involves the input and can select the majority of the output lines of the data that are plugged towards the input device. The majority of the multiplexers are mainly coupled with a dumex at the conclusion to get data. The symbol that is representative of the Mux is really a two sided equal trapezoid which has the length wise side that contains the pins of input and the narrow side that contains the pins of output.

A Mux Demux will work largely by combining and separating the two optical signals which are present on different band widths that potentially double the amount capacity from the data, that is installed on the fiber plant. The only Mux terminal goes through both the bandwidths. The Demux that is of two fiber segregates particular bandwidth signal and passes onto a dedicated fiber strand and just the passive cable will allow the flow both in the directions. Both Mux and Demux are transparent to many of the networks and protocols. The reflections that are obtained by the signals are deleted by the existence of angled polished connectors that are present in the interface. Utilization of these cables will help in high segregation and occasional polar dependence.

FiberStore is definitely an China company that specialises in selling quality network connection parts. All of our multiplexer and demultiplexer possess a best warranty and incredibly competively priced as well as being of the most useful. For instance, the 100G DWDM Mux Demux can be used to provide 100G transport solution for DWDM networking system. The most popular configuration is 4, 8, 16 and 32 channels, and that we also provide 40, 44 channels. These DWDM modules passively multiplex the optical signal outputs from 4 or even more electronic devices, send them over a single optical fiber after which de-multiplex the signals into separate, distinct signals for input into electronics in the opposite end from the fiber optic link. Our standard 100G DWDM Mux/Demux package types are ABS box package, LGX package and 19 1U rackmount. We also supply custom package to meet your requirement. Here you can purchase DWDM Mux Demux modules from fiber optic products worldwide online shop with confidence.

Industrialization of PLC splitter chip technology

Industrialization of PLC splitter chip technology

Fiber optic communication network has become the cornerstone of today’s world of information transfer. With the further development of the network and market demand for communication bandwidth increases, the entire communication network to the part between the user’s last ten km and last km, the network part is also being optical fiber. FTTH becomes an important direction of the development of fiber optic communication network.

FTTH mainly uses PON network technology, which requires a large number of low-cost optical splitters and other optical passive. Optical splitter device is an integral part of FTTH, and with the promotion of FTTH, there would be a great market demand. The traditional preparation of optical splitter technology is fiber fused biconical taper (FBT) technology. Its characteristics are mature and simple technology. The disadvantage is that the assigned ones too large, and the device size is too large, which causedthe decrease in yield and the rising cost of single channel, shunt reactive stars uniformity will deteriorate. FBT technology based fiber optic splitter preparation techniques have been unable to adapt to the market demand.

As you can see from the perspective of development of optical devices, PLC technology has become a mainstream technology for large-scale preparation of high-performance and low-cost optical splitter. It is the use of PLC technology, to produce the optical splitter chip, coupled with the optical fiber array package, complete the preparation of the optical splitter. Its features are: small size of the device, the cost is relatively low, splitter good uniformity, at the same time, the technical threshold is relatively high, especially for production of more than large ones optical splitter, suitable for mass production. It can ensure that the light emitting device miniaturization, low cost and high performance. Analysis of PLC technology, you can see that the glass-based PLC technology has great advantages in terms of equipment investment, production costs, the optimal choice of production required for fiber-to-the-home, low-cost optical devices such as optical splitter.

International, PLC technology has been widely used in the miniaturization, high-performance optical device fabrication and production, in particular, the optical splitter chip. In China, however, the reality is that we have become a PLC encapsulation big country, but is limited to the optical splitter and optical device fabrication device coupled packaging and downstream industry chain, no one PLC chip Health line, PLC core device chip entirely dependent on imports. Which there is a problem that the core preparation technique of the PLC device lies in the outward, this has resulted in major cost control of the device is limited in the chip at the same time, which also led to the lack of technical support further to the high-end integrated chip development, severe hinder the development of our country in the PLC application.

PLC splitter chip manufacturing process PECVD (plasma enhanced chemical vapor deposition) and FHD (flame hydrolysis deposition) and ion exchange. The former two with the substrate material is a silicon-based silica, and the latter with the substrate material is glass. AWG (arrayed waveguide grating) chip production, Silica optical waveguide splitter chips can be produced on silica on silicon waveguide or glass waveguide. Production by ion exchange glass waveguide PLC chip domestic number of colleges and universities have been conducting research and development, technical appraisal sample has been reached the international advanced level of similar products. The breakthrough of the results from the glass material, preparation equipment, process conditions designed to chip a full range of core technology to master the the buried low loss and low polarization characteristics PLC chip core preparation techniques.

Characteristics of the technology investment, equipment operation and low maintenance costs, simple process conditions, the production of optical passive low transmission loss and polarization characteristics with matching coupling of the fiber loss, environmental stability, and manufacturing costs low, very suitable in need of the PLC production line, can be used for producing low-cost fiber-to-the-home integrated optical splitter chip. Further pilot research and development, to solve adapted to the production of core technology, will be able to achieve your PLC splitter chip mass production.

In fact, in addition to the production of optical splitter chip, glass-based PLC technology R & D production environment with a wide range of other potential applications, for example, can be applied to detect the required light sensor.

Production Process of Fiber Optic Splitter with Advantages and Disadvantages

Production Process of Fiber Optic Splitter with Advantages and Disadvantages

Fiber optic splitter (optical splitter) is also known as “non-wavelength selective optical branching device”. It is a fiber optic device used to achieve a particular band optical signal power splitter and redistribution.

Optical splitter can be used as a stand-alone device in the OLT node, the light distribution point and the FTTH point. It can also be placed in the central office wiring facilities, the light distribution points and FTTH points within the facility (integrated design or plug-in).

In accordance with the production process, optical splitters are divided into Fused Bi-conical Taper (FBT Splitter) and Planar Lightwave Circuit (PLC Splitter).

FBT Splitter (FBT Coupler)

Fused Bi-conical Taper technique is tied to two or more fibers, and then melted in a cone machine, pull tensile and real-time monitoring of changes in splitting ratio, the splitting ratio to meet the requirements after the end of the melt stretching, and wherein one end of a fiber optic reserved ( The remaining cut off) as the input terminal and the other end a multitude of road outputs. Mature tapering process can only pull 1 × 4. 1 × 4 or more devices, with a plurality of 1 × 2 connected together. Then the overall package in the splitter box.

(1) pull taper coupler over twenty years of history and experience, many equipment and processes simply follow the only development funds only a few of the PLC tenth or hundredth of a few
(2) Raw materials only readily available quartz substrate, fiber optics, heat shrink tubing, stainless steel pipe and less plastic, a total of not more than $ 1. Investment in machinery and equipment depreciation costs less, 1 × 2,1 × 4 and other low-channel splitter low cost.
(3) splitting ratio can be real-time monitoring, you can create unequal splitter.

(1) Loss of light sensitive wavelength ships according to the wavelength selection device, in this triple-play during use is a fatal defect, since the triple play of light transmitted signal 1310nm, 1490nm, 1550nm, and other multiple-wavelength signal.
(2) poor uniformity, 1×4 nominal about 1.5dB away, 1 × 8 or more away from larger, can not ensure uniform spectroscopic, which may affect the overall transmission distance.
(3) Insertion loss varies with temperature variation is greater (TDL)
(4) multi-demultiplexer (e.g., 1 × 16,1 × 32) volume is relatively large, the reliability will be reduced, the installation space is restricted.

PLC Splitter

Planar waveguide technology is the optical waveguide branching device with a semiconductor production process. The branching function is completed on the chip. On one chip to achieve up to 1X32 splitter, then, at both ends of the chip package input terminal and an output terminal respectively coupled multi-
Channel optical fiber array.

(1) The loss of transmission is not sensitive to the wavelength of light, to meet the transmission needs of different wavelengths.
(2) spectroscopic uniform signal can be uniformly allocated to the user.
(3) compact structure, small size, can be installed directly in the existing junction box, no special design leave a lot of space for installation.
(4) only a single device shunt channel can achieve much more than 32 channels. (5) The multi-channel, low cost, stars ones more and more obvious cost advantages.

(1) Device complex production process, high technical threshold, the chip is several foreign companies to monopolize domestic bulk package production companies only Borch rarely several.
(2) relative to the higher cost of Fused Splitter more at a disadvantage, especially in the low channel splitter.
