The Difference Between PLC Splitter and FBT Splitter

With the huge demand for electronic communication in modern society, fiber optic cable splitter play an important role in optical propagation. We know that fiber splitter can be divided into PLC Splitter (Planar Lightwave Circuit Splitter) and FBT Splitter (Fused Biconical Taper Splitter) according to the manufacturing process. This article will explain the difference between PLC Splitter and FBT Splitter and how to choose the right fiber optic splitter.

What is PLC Splitter?

As an optical power distribution device, <a href=””>PLC optical splitter</a> is used to connect the optical signal from the entrance end, and then transmit it uniformly to the optical fiber from the output end. It is made by semiconductor technology, and it is usually made of quartz. Due to its small size, high stability, and uniform light distribution, it has gradually become a popular choice in communication networks.

What is FBT Splitter?

A fused cone splitter bundles two or more fibers together, then melts and stretches them, leaving one fiber as the input and the other as the output. FBT fiber splitter appeared decades earlier than the PLC fiber splitter, so both the proficiency and popularity of his production process are better than the PLC optical splitter. It can be said that it is still the most common splitter in current communication.

Differences Between PLC Splitter and FBT Splitter

  • Spectroscopic uniformity

The uniformity of the FBT optical splitter is poor and cannot ensure uniform light splitting, which may affect the overall transmission distance. The PLC optical splitter can split the light evenly and distribute the signal evenly to the users. PLC splitter loss is also small.

PLC Splitter vs FBT Splitter

  • Production Cost

The raw materials for FBT fiber splitter are cheap and easy to obtain, and there are many years of manufacturing technology, while the process of the PLC splitter manufacturing is complicated and the technical threshold is high. So, compared with PLC optical splitter, the production cost of FBT splitter is smaller.

  • Installation Space

The PLC splitter is compact in structure and small in size, and does not require a large installation space. The FBT splitter is generally larger in size and needs to reserve a larger installation space.

  • Signal Transmission

Reading the above, it can be seen that the PLC splitter is very stable, and the optical signal can be transmitted evenly at the output end. Due to the influence of the manufacturing process, the FBT splitter is difficult to transmit the optical signal uniformly in the optical signal transmission.

  • Suitable Working Temperature

Temperature may be a key factor affecting optical devices. The normal operating temperature range for FBT splitter is -5 to 75°C. PLC splitter can work in a wider temperature range of -40 to 85 °C, so PLC splitter have a wider range of use than FBT splitter, such as providing relatively good performance in extreme climate areas.

  • Application Field

Both are widely used in FTTH optical splitter fiber communication system, optical fiber local area network, CATV, FTTH. In addition, PLC optical splitter has wider application than FBT optical splitter because of its small size.

How to Choose the Right Fiber Optic Splitter

After reading the above content, I believe that everyone has a basic understanding of the fiber optic splitter. As an optical power splitter device, <a href=””>PLC splitter</a> and FBT splitter in the fiber optic splitter. So how to choose the most suitable fiber optic splitter?
First of all, you can choose according to the level of the budget. If the budget is high, you can choose the PLC splitter, and if the budget is low, you can choose the FBT splitter.
Secondly, you can look at the wavelength requirements and transmission distance. If the transmission distance is long, the PLC splitter should be selected. If the transmission distance is short, the FBT splitter will be a good choice. If it is used in normal areas, then both can be selected. But in some areas with severe weather, it is better to choose PLC splitter. The last but important point that is easily overlooked is how much installation space is needed. If the installation space is small, the PLC splitter must be selected. If the installation space is large, both can be selected.

         All in all, the FBT splitter is cheap and the manufacturing process is mature, but there are many limitations, while the PLC splitter is more expensive, but has better performance. In recent years, compared with the traditional FBT splitter, the excellent quality and excellent performance of the PLC splitter have made it appear more in people’s field of vision, and many developed countries have almost chosen more cost-effective PLC splitter. It is believed that in the near future, PLC splitter will gradually replace FBT splitter and become the mainstream of the market.

As a professional plc splitter manufacturer, Baudocm can provide types PLC optical splitter, 1×2 plc splitter, 1×4 plc splitter, 1×8 plc splitter, 1×16 plc splitter, 1×32 splitter.

Lomoveishiy – Finland

I needed those to connect my PC on the third floor to have internet access in that room, and ISP installed their modem on the first floor only. After dropping fiber patch cables, plugged in all cables into these media converters at both sides, and link came up instantly. Was much easier than I thought!

Raymond – USA

Great experience – units worked straight out of the box – just needed plug in cables and we were done. I also like the possibility to enable jumbo frames, while we do not have a need for this feature at the current moment it’s great to have this option.
