What is a PLC Splitter?

A plc splitter is a micro-optical component that is based on planar lightwave circuit technology and provides a low cost light distribution solution with small form factor and high reliability. It is manufactured using silica glass waveguide circuits that are aligned with a v-groove fiber array chip that uses ribbon fiber.


A plc splitter is one of the most cost-effective LAN components. This is because it can be used in a variety of network types, including GPON, EPON, BPON and FTTX. It can also be used in a distributed or centralized configuration, depending on the requirements of the customer.

PLC splitters are based on planar lightwave circuit technology and have three layers: a substrate, a waveguide and a lid. The waveguide plays a critical role in the splitting process, allowing a specific percentage of light to pass through. Moreover, they come in a wide range of split ratios, such as 1:4, 1:8, 1:16, and 1:32.

The most important advantage of a plc splitter is its ability to distribute or combine multiple optical signals. It can divide a single fiber optic signal into multiple strands, which can be used to transmit the signal to subscribers. This feature makes it a popular choice for telecom companies and fiber to the home (FTTH) networks.

Another benefit of a plc splitter is its low insertion loss, which helps to reduce the number of faults in a network. Moreover, it can work stably in a wide temperature range.

This feature is especially beneficial in harsh environments. In addition, a plc splitter is easy to install and maintain. Its compact structure can help to save space and minimize the installation costs, thereby making it an ideal choice for network transformation projects.

When choosing a plc splitter, a project manager may consider factors such as the type of network, the wavelength that the fiber optic signal must travel, and the port configurations that the fiber will need. Then, he or she can choose the most suitable plc splitter for the application.

As a result, the quality of the plc splitter is more important than its price. A plc splitter that is low quality could cause costly problems in the future, which is why it is important to choose a high-quality plc splitter when planning your network.

The cost of a plc splitter is generally higher than that of an FBT splitter, but this can be offset by the quality of the device and its performance. A quality plc splitter is much more reliable, and will save you money in the long run.


PLC Splitter, based on Planar Lightwave Circuit technology, is a cost effective and space saving networking solution for FTTx & FTTH networks. It enables optical power allocation from central office to number of promises, and distributes the signal evenly through silica optical fibers.

Various types of PLC splitters are available, including bare fiber PLC splitter, blockless PLC splitter with fan-out, fanout PLC splitter and mini plug-in type PLC splitter. Each type of plc splitter has a different package form factor and is designed to meet the specific requirements of different applications.

The most common type of plc splitter is the bare fiber plc splitter. This type of plc splitter has a compact stainless tube package. It is widely used in fiber to the home (FTTH) passive network.

Bare fiber plc splitters are terminated with fiber optic connectors on all sides, which makes plc splitter it easy to be spliced by the network engineers according to their needs and the space required in fiber cabling. In addition, a bare fiber plc splitter requires the least amount of cabling space during installation.

Another popular plc splitter is the fanout PLC splitter, which uses a fan-out block to divide one wavelength into multiple ports. This design saves space by enabling smaller splitter modules.

In addition to these, the fanout PLC splitter also provides a better port uniformity and higher reliability than the other types of plc splitters. It is a space-saving and cost-effective solution for GPON and EPON deployments, and can be installed in underground, aerial, pole, pedestal and rack systems.

As a professional plc splitter manufacturer, Fiberstore offers different types of plc splitters with high performance and good quality. Our plc splitters are able to meet the Telcordia GR-1209-CORE and GR-1221-CORE reliability qualification requirement, and they work in temperatures from -40°C to 85°C.

Besides the plc splitter, we also offer many other types of splitters, such as the sfo (splitter fan out) cable system. This system combines the functions of patch cord, splitter box and fan-out cable in one product, which reduces installation time, improves maintainability and allows for up to 30% rack space savings.

Easy to install

Whether you are looking for a single-mode PLC splitter or a multimode one, there is a variety to choose from. The single-mode ones can have a variety of splitting ratios from 1:2 to 1:64 and are available with either 250 or 900um fiber optic tubes. They also come with a choice of connectors to connect to your fiber optic network such as LC or SC.

The multimode splitters are available in a variety of split ratios as well and are typically designed to be used with LC plc splitter or SC connectors. These devices are suitable for a wide range of applications including passive optical networks (PON).

A plc splitter is a passive component that divides a single strand of fiber optic signal into several strands that can then be shared among multiple subscribers. It is a common device used for the distribution of GPON, EPON and BPON signals.

As a plc splitter is based on planar lightwave circuit technology, it is easy to install. It is often installed in a fiber distribution box or rack to save space and can be paired with other plc modules to increase capacity.

When installing a plc splitter, it is important to remember that unused fibers and connectors should be properly capped. This will keep them clean and reduce the possibility of misconnections.

There are many types of plc splitters to choose from, some of which can be installed in a small plastic box. Others can be installed in a 19-inch rack unit or cross connect cabinet to save space and simplify cabling.

Another type of plc splitter can be installed in a tray. This is a unique design which can be deployed in a 19-inch rack or ODF to save space and simplify cable management. The ports on a tray plc splitter are clearly marked to avoid misconnections and reduce faults.

The PLC chips on these components are manufactured with Plasma Chemical Vapor Deposition (P-CVD) technology and the silica on silica waveguide and optical fiber array are tested to Telcordia GR-1209 and GR-1221 standards. The resulting splitters are highly reliable and offer low insertion loss, low polarization dependent loss (PDL), and high port uniformity.

Easy to maintain

One of the reasons that PLC splitter is so popular in today’s fiber optic network is the ease of maintenance. This is a particularly important factor for FTTx networks that are often in the field for a long time. It’s important to understand how the equipment is maintained to prevent downtime, which can cost money and negatively impact network performance.

One way to maintain the equipment is to use an industrial strength lubricant on the shafts and bearings. This will reduce the wear and tear that can happen over time with the high temperatures that come with long term field deployment. In addition to a regular checkup, a periodic cleaning can help ensure the equipment is performing at its best.

A good lubricant will also help remove the buildup of static electricity on the shafts and bearings, which is another common cause of failure in this environment. This will improve the lifespan of the equipment and allow service providers to focus on providing their subscribers with a great product.

The most difficult task is determining the correct amount of lubricant to use on the shafts and bearings. A judicious application of this solution can save the customer thousands in the long run.

The best way to do this is to purchase a large sized bottle of lubricant and then use a syringe to squirt some onto the shafts and bearings. The resulting lubricant should have a nice sheen to it. This will help eliminate the buildup of static electricity that can lead to costly downtime in this environment.
