The right way to Choose Fiber Optical Splitter

How to Choose Fiber Optical Splitter

Fiber optic splitters play an increasingly significant role in many of today’s optical network topologies. They provide capabilities that help users maximize the functionality of optical network circuits from FTTx systems to traditional optical networks. And usually they are placed in the central office or in one of the distribution points (outdoor or indoor).


What Is Fiber Optic Splitter?


A fiber optic splitter is a passive optical device that can split or separate an incident light beam into two or more light beams. These beams may or may not have the same optical power as the original beam, based on the configuration of the splitter. By means of construction, the outputs of an optical splitter can have varying degrees of throughput, which is highly beneficial when designing optical networks, whether the optical splitter is used for network monitoring or for a loss budget in passive optical network (PON) architecture. Generally, there are two types of fiber optic splitters, which are FBT splitters and PLC splitters.


FBT Splitter


FBT splitter is one of the most common splitters, which is widely accepted and used in passive networks. FBT splitter is designed for power splitting and tapping in telecommunication equipment, CATV network, and test equipment.


PLC Splitter


PLC splitter is a hot research at home and abroad today, with a good prospect of application, which is used to distribute or combine optical signals. It is based on planar light wave circuit technology and provides a low cost light distribution solution with small form factor and high reliability.


Applications for PLC Splitter


Bare Fiber PLC Splitter


Bare fiber PLC splitter has no connector at the bare fiber ends. It can be spliced with other optical fibers in the pigtail cassette, test instrument and WDM system, which minimizes the space occupation. It is commonly used for FTTH, PON, LAN, CATV, test equipment and other applications.


Blockless PLC Splitter


Likewise, blockless PLC splitter has a similar appearance as bare PLC splitter. But it has a more compact stainless tube package which provides stronger fiber protection, and its fiber ends are all terminated with fiber optic connectors. Connectors are commonly available with SC, LC, FC and ST types. Thus, there is no need for fiber splicing during installation. Blockless PLC splitter is mainly used for different connections over distribution boxes or network cabinets.


ABS PLC Splitter


ABS PLC splitter has a plastic ABS box to protect the PLC splitter to adapt to different installation environments and requirements. Common splitter modules are 1×4, 1×8, 1×16, 1×32, 1×64, 2×4, 2×8, 2×16, 2×32. It is widely used with outdoor fiber distribution box for PON, FTTH, FTTX, PON, GOPN networks.


Fanout PLC Splitter


PLC splitter with fan-out is mainly used for 0.9mm optical fiber where the ribbon fiber can convert to 0.9mm optical fiber through fan-out. 1×2, 1×4, 1×8, 1×16, 1×32, 1×64, 2×2, 2×4, 2×8, 2×16, 2×32, 2×64 fanout types are all available with PLC splitters. Fiber adapters can also be used for the input and output ends of this kind of splitters to directly meet the demand on smaller size of splitters.


Tray Type PLC Splitter


Tray type PLC splitter can be regarded the fiber enclosure which contains PLC fiber splitter inside a enclosure. It is often directly installed in optical fiber distribution box or optical distribution frame. FC, SC, ST & LC connectors are selective for termination. Tray type PLC splitter is an ideal solution for splitting at the places that are near OLT or ONU.


Rack-mount PLC Splitter


Rack-mount PLC splitter can be used for both indoor and outdoor applications in FTTx projects, CATV or data communication centers. It uses the 19-inch rack unit standard to contain the PLC splitter inside a rack unit.


LGX PLC Splitter


LGX PLC splitter or LGX box PLC splitter has a strong metal box to house the PLC splitters. It can be used alone or be easily installed in standard fiber patch panel or fiber enclosure. The standard LGX mental box housing provides a plug-and-play method for integration in the network, which eliminates any risk during installation. No filed splicing or skilled personnel is required during deployment.


Mini Plug-in Type PLC Splitter


Similar to the LGX PLC splitter, mini plug-in PLC type splitter is its small version with a compact design. It is usually installed in the wall mount FTTH box for fiber optic signal distribution. Using the mini plug-in PLC type splitter saves time and space but still provides reliable protection for the fiber optic splitter.

Common Armored Fiber Optic Cables

  Armored fiber optic cables are often installed in a network for added mechanical protection, as they have extra reinforcing in the cable housing to prevent damage. Two types of armored fiber optic cables exist: interlocking and corrugated. Interlocking armor is an aluminum armor that is helically wrapped around the cable and found in indoor and indoor/outdoor cables. It offers ruggedness and superior crush resistance. Corrugated armor is a coated steel tape folded around the cable longitudinally. It is found in outdoor cables and offers extra mechanical and rodent protection.   The Structure of an Armored Fiber Optic Cable In basic armored fiber cable designs, the outer sleeve provides protection against wind, solvents, and abrasion. This outer sleeve is usually made of plastic such as polyethylene. The next layer between the sleeve and the inner jacket is an armoring layer of materials that are difficult to cut, chew, or bu

what the Differences Between FBT Splitter and PLC Splitter

  In FTTx and PON architectures, optical splitter plays an increasingly significant role to create a variety of point-to-multipoint fiber optic networks. But do you know what is a fiber optic splitter? In fact, a fiber optic splitter is a passive optical device that can split or separate an incident light beam into two or more light beams. Basically, there are two types of fiber splitter classified by their working principle: fused biconical taper splitter (FBT splitter) and planar lightwave circuit splitter (PLC splitter). You may have one question: what’s the difference between them and shall we use FBT or PLC splitter?   What Is FBT Splitter? FBT splitter is based on a traditional technology to weld several fiber together from side of the fiber. Fibers are aligned by heating for a specific location and length. Because the fused fibers are very fragile, they are protected by a glass tube made of epoxy and silica powder. And then a stainless steel tube covers the inner glass tu

Introduction of Optical Fiber Couplers and How Do They Work?

 What are optical fiber couplers? A fiber optic coupler can be defined as an optical component used with one or more input fibers and several output fibers in fiber optic systems. A coupler essentially puts two or more cores of fibers together to connect. The simple coupler is the fused fiber 2x2 coupler. Couplers are used as multiplexers that are resistant to certain wavelengths. A fiber output depends on the wavelength of light and the frequency of polarization. The fiber refractive index also plays a significant role in the performance. Let’s checkout how do optic couplers work to understand this better. How do fiber optic couplers work? Either fiber optic couplers separate optical signals into multiple paths or combine multiple signals in one direction. Optical signals are more complicated than electrical signals, making it more difficult to design optical couplers than their electrical copy. Unlike electrical currents, the optical signal consists of a stream of signal carriers, in
