Fiber PLC splitter is a kind of fiber optic light into a certain percentage of the device. For example, when a bundle of fiber light is emitted from a 1X4 equal-splitter, it will be split into 4 fiber lights in equal proportions, ie, each light beam is 1/4 or 25% of the original light source. Optical splitters and WDM different. WDM can be divided into different wavelengths of optical fiber channel. Optical splitters separate optical power and send it to different channels.
Optical networks require that the signal be split somewhere in the design to serve multiple customers. Splitter technology has taken a big step forward in the past few years by introducing a PLC (Planar Lightwave Circuit) splitter. It has proven to be a more reliable device than the traditional FBT (melt double cone) separator. Although similar in size and appearance, these two types of separators provide data and video access to commercial and private customers. However, the technologies behind these types are internally different, so service providers may choose the more appropriate solution.
The FBT splitter is made of readily available materials such as steel, fiber, hot dorm and more. All of these materials are low-priced, which determines the low cost of the device itself. Device manufacturing technology is relatively simple, the price has an impact. The size of the device can be a problem when multiple splits are required. It is important to remember that the splitter is being deployed in the area of cabinets or wiring harnesses so the size of the device plays a crucial role.
Fiber PLC splitter manufacturing technology is more complicated. It is manufactured using semiconductor technology (lithography, etching, development technology) and is therefore more difficult to manufacture. Therefore, the equipment is more expensive. However, this device has many advantages. Compared with the FBT separator, the device is compact and suitable for density applications. In addition, due to the technical implementation, the signal can be divided equally. Offering a range of wavelengths (1260 - 1650 nm), the wavelength can be adjusted. The key points for equipment that may fail are input and output, so the general risk of failure is low.
