UT-King's FBT (fused biconical taper) is the traditional technology in which two fibers are placed closely together, typically twisted around each other and fused together by applying heat while the assembly is being elongated and tapered. A signal source controls the desired coupling ratio. The fused fibers are protected by a glass substrate and then protected by a stainless steel tube, typically 3 mm diameter by 54 mm long. FBT splitters are widely accepted and used in passive optical networks. The following picture shows a 1×2 FBT splitter single-mode three window fiber splitter with ABS box.

Note: 1. All parameters are for device without connectors.
2. Special specifications can be customized according to customer requirements.
FBT splitter only supports three wavelengths: 850nm, 1310nm, and 1550nm, which makes its inability to work on other wavelengths. The PLC splitter can support wavelengths from 1260 to 1650nm. The adjustable range of wavelength makes PLC splitter suitable for more applications.
Splitting ratio is decided by the inputs and outputs of an optical cable splitter. The maximum split ratio of FBT splitter is up to 1:32, which means one or two inputs can be split into an output maximum of 32 fibers at a time. However, the split ratio of PLC splitter is up to 1:64 - one or two inputs with an output maximum of 64 fibers. Besides, FBT splitter is customizable, and the special types are 1:3, 1:7, 1:11, etc. But PLC splitter is non-customizable, and it has only standard versions like 1:2, 1:4, 1:8, 1:16, 1:32, and so on.
The signal processed by FBT splitters cannot be split evenly due to a lack of management of the signals, so its transmission distance can be affected. However, PLC splitter can support equal splitter ratios for all branches, so it is more stable.
FBT splitter is typically used for networks requiring the splitter configuration of less than 4 splits. The larger the split, the greater the failure rate. When its splitting ratio is larger than 1:8, more errors will occur and cause a higher failure rate. Thus, FBT splitter is more restricted to the number of splits in one coupling. But the failure rate of PLC splitter is much smaller.
In certain areas, the temperature can be a crucial factor that affects the insertion loss of optical components. FBT splitter can work stable under the temperature of -5 to 75℃. PLC splitter can work at a wider temperature range of -40 to 85 ℃, providing relatively good performance in the areas of extreme climate.
Owing to the complicated manufacturing technology of PLC splitter, its cost is generally higher than the FBT splitter. If your application is simple and short of funds, FBT splitter is definitely a cost-effective solution.
