What is the difference between FBT optical fiber seminars and PLC fiber fiber?

The fiber seminars play an increasingly important role in today's optical network. From the FTTX system to the traditional optical network, it can not only enable many users to share a fiber interface, but also help users to expand the function of optical network circuits to the greatest extent. Today we will briefly introduce the fiber fiber.

With the continuous development of modern technology, a variety of optical fiber segments appear in the market.

The two most common types are: melting cone fiber fiber seminars (FBT fiber seminars) and plane waveguide optical fiber seminars (PLC optical fiber seminars).

In addition to the difference between size and appearance, there are many differences in other places.

1. Material

FBT fiber seminars are made of steel, fiber, thermal tube, and other common materials. Because the cost of these materials is not high and the device manufacturing technology is relatively simple, the price of the FBT fiber seminars is cheaper. The technology of the PLC fiber seminars is more complicated and expensive. It uses semiconductor technology for production, which greatly increases the difficulty of manufacturing, so its cost is high.

2. Work wavelength

FBT optical fiber separators only support three wavelengths: 850nm, 1310nm, and 1550nm, and cannot work in other wavelength environments.

The PLC optical fiber seminars can support work at the wavelength of 1260nm to 1650nm. It can be seen that the wavelength range supported by the PLC fiber optic width is more extensive.

3. Diversion ratio

The diversion ratio of FBT optical fiber seminars is as high as 1:32, and the PLC optical fiber seminars can rise to 64, which allows the PLC optical fiber to provide higher reliability. In addition, based on higher technology, the PLC optical fiber seminars can split the signal equivalent.

4. Temperature

Temperature is a key factor affecting the performance of optical devices. Therefore, it plays a vital role in the performance of the equipment. The FBT optical fiber seminars can work stable at -5 ℃ ～ 75 ℃, while the PLC optical fiber seminars can work at a wider temperature range of -40 ℃ ～ 85 ℃, and they can play well in such an extreme environment. performance.

In addition to the above differences, there are other differences in the FBT fiber seminars and the PLC fiber seminars. For example, the size of the PLC optical fiber seminars is more compact than the FBT optical fiber. Therefore, the PLC optical fiber seminars are more suitable for high -density applications.
