![]() Splitting an incident light beam into two or more light beams or vice versa, Fiber optic splitter or referred to as beam splitter is a passive optical component. Multiple input and output ends are present in a fiber splitter. For the convenience of network interconnections in a network, a fiber optic splitter is implemented whenever there is a requirement of the division of light transmission. Working of Fiber Optic Splitter Whenever there is the transmission of the light signal in a single-mode fiber, the light energy is not able to concentrate in the fiber core. Through the cladding of fiber, a small amount of energy is spread. The light-transmitting in a fiber adapter can enter into another optical fiber now if two fibers are enough for each other. Therefore, in the optical signal, the reallocation technique can be achieved in multiple fibers. Classification of Fiber Optic Splitter: There are two types of fiber optic splitter, one is a PLC splitter another is an FBT splitter PLC Splitter PLC is referred to as a planar lightwave circuit. There is a light circuit present at the edge of the chip that to in a ribbon form mounted on a carrier and fibers. As the material of lightwave circuit PLC splitter typically adopts silica glass and it also accepts various types of polished finishes. In a PLC splitter the substrate, waveguide, and lid are three basic layers. FBT Splitter To fuse several fibers FBT or fused biconical taper make use of the traditional technology. For a specific location and length, the alignment of fibers is done by heating. Until the parameters of the fiber collimator reach the required standards there will be no stopping for the fusion process. Fused fibers are very fragile; as a result, they are protected by a glass tube that is made of epoxy and silica powder. For the convenience of network interconnections, a fiber optic splitter is used. PLC splitter provides better performance and fewer limitations, but if you have budget limitations then FBT splitter is less expensive. You can even take the help of a professional if you are still not sure which one to choose. Main source: fibermarts.wordpress.com/

![]() An optical attenuator is a device that is used to reduce the intensity of a light beam, i.e., reducing its optical power. The amount of attenuation can be said in terms of an optical density or decibels, at times you can even say it in percent of transmitted or blocked optical power. Basic Requirements In few cases, there is a need for a fixed degree of attenuation, whereas in some other cases one may find the requirement of the variable optical attenuator (VOA), where you can adjust the degree of attenuation, for example manually using any knob. Having a stepwise variable attenuation can be the ultimate solution. You will find that with the help of an electronic signal you can control the adjustment of the attenuation. The device gets converted into an optical modulator if you make this adjustment very fast. The attenuation of power must be done in such a way that the transverse beam profile is not affected. This case happens for example when there is a need for a high-power laser to be characterized with the help of a beam profiler that can handle only a limited amount of optical power. The problem can occur when the beam profile is distorted by the attenuator. When you work with high-power laser beams, the power handling capability of an optical isolator may be another essential aspect that you must consider. Safeguarding the detrimental effects on the attenuated beam, such as thermally induced changes of the attenuation degree of beam distortions along with safely avoiding damage of the attenuator is essential. There are different optical attenuators to free-space beams that are applicable, whereas, for waveguides of other kinds, others are of a fiber-optic type or work. Fiber-optic Attenuators In the context of fiber optics, various types of optical attenuators can be used. Placed between two lenses, a few of them just contain some type of bulk-optical attenuator for collimating the beam. On the other hand, optical circulator is a purely fiber-optic device.
