Optical Fiber Fusion Splicer Types (Fusion Splicing Machines) Explained in Detail

:: What is Fusion Splicing? Fiber splicing is the process of permanently joining two fibers together. Unlike fiber connectors, which are designed for easy reconfiguration on cross-connect or patch panels. There are two types of fiber splicing – mechanical splicing and fusion splicing. Mechanical splicing doesn’t physically fuse two optical fibers together, rather two fibers are held butt-to-butt inside a sleeve with some mechanical mechanism. You will get worse insertion loss and back reflection in mechanical splices than in fusion splices (the second type we are introducing below).Mechanical splicing is mostly used for emergency repairs and fiber testing. You can

Mode Field Diameter Mismatch Loss Between Two Single Mode Fibers

The loss associated with mode field diameter (MFD) mismatch between single mode fibers is Differences in the mode field diameter between single mode fibers (of the same type or different types) lead to a signal loss. The above equation can be used to estimate the loss and can be used with the measured or specified MFD, or the uncertainty of the MFD. The user should realize that MFD is a function of wavelength and changes across the G and L bands, as illustrated below.     There are several companies manufacturing dispersion devices. Each company should supply MFD and Aeff

Optical Fiber Stripping

You can get optical fiber stripper from Fiber Optics For Sale Co. >> Single Fiber Coating Structure Depending on fiber’s application, different optical fiber coating designs exist. However, 250um UV coating is the most popular among today’s single mode and multimode bare fibers. The following illustration shows this common design. The polymer coating is a soft, UV cured, urethane acrylate. It has a higher refractive index than the cladding layer, so it can strip out unwanted light. This polymer coating may consist of one or two layers. If there are two layers, the inner layer is called primary coating and

How to Achieve Lowest Fiber Splicing Loss

:: What factors affect optical fiber splicing loss? There are two types of factors that fiber splice loss depends on: intrinsic factors and extrinsic factors. So let’s talk about intrinsic factors first. :: Mode Field Diameter Mismatch Intrinsic factors are parameters that you can not control. These factors are determined when the fiber is manufactured and Mode Field Diameter (MFD) is the most critical one. Differences in the mode field diameter between single mode fibers lead to a signal loss. More splice loss can be observed for higher difference in MFD values. Here is the formula that calculates splice loss
