Optical splitters play an important role in the PON infrastructure. These splitters are actually beam splitters and split a beam of a certain frequency into smaller optical signals that pass through a single optical fiber to the ONU. In this way, by deploying separate optical components for each end user, the needs of a large number of three play service users are met without disrupting the network.
The technology for making PLC dispensers is a bit more complicated than the techniques used in FBT. So PLC dispensers are more expensive than the latter. However, this is the only difference that favors the FBT splitter. The result achieved at this extra cost is even more wonderful, which can be called an advance in PLC technology. With the help of etching, semiconductor technology is better understood, and lithography and development are not easy. This will definitely increase the cost of the equipment.
However, the benefits of buying a fiber PLC splitter are numerous. First, it allows the device to have a smaller and more compact shape. As a result, it can be used in denser applications and more compact spaces, helping to add more modularity to the entire PON fabric. PLC operating temperature range is -40 to 85 degrees Celsius. This of course is wider than the FBT can work in. Although there are many split ratio options in the FBT, the PLC can deliver up to 1:64 rationing and accommodate up to 1024 end users.
Fiber PLC splitter show better signal management and provide uniform signal separation. This helps to achieve better performance and more capacity in the network. PLCs are more flexible than FBTs in that they can support a wider range of wavelengths between 1260nm and 1620nm. Therefore, the wavelength adjustment is no problem.
