Understand The Technology Of The Fiber Plc Splitter

Glass ion exchange technology has been used for hundreds of years. It was first used to change the light absorption characteristics of glass and then used to color glass. The technology is widely used to process the surface of glass surface (such as hard touch by touch screen). With the development of optical communications, its good environmental stability and compatibility with optical fibers are beginning to be widely used in the manufacture of optical communication components (such as self-focusing lenses, optical splitters, optical amplifiers, etc.) and in the field of sensing Such as various biological and chemical sensors, current sensors based on fading light waves, etc.). The current PLC distributor chip mainstream technologies include: PECVD technology, flame hydrolysis technology, glass ion exchange technology. Ion exchange glass technology and process technology. Comparison of process characteristics in Table 1. From the service life and reliability of the experiment, the two technologies PECVD / flame hydrolysis technology is characterized by equipment and raw materials are the existing materials, but the process is complex, long production cycle, the processing error is small; glass ions Switching technology is characterized by equipment and raw materials need special customization, but its technology is relatively simple, high efficiency, larger process tolerances, lower chip costs. Fiber PLC splitter is a fiber optic light into a certain percentage of the equipment. The simplest coupler is a PLC splitter. These devices have at least three ports, but may have more than 32 ports for more complex devices.Fiber PLC splitters are important passive components used in FTTX networks. However, two types of fiber optic splitters are commonly used, one is a conventional type PLC splitter (FBT splitter) at a competitive price, and the other is a PLC splitter which is small in size and suitable for density application. Both have their advantages to meet different requirements. Typical parameters for a fiber PLC splitter include the cable length of the input and output sections, splitting ratio, operating wavelength, and what kind of fiber optic connectors. Like fiber jumpers, fiber optic splitters typically use 0.9mm, 2mm or 3mm cables. The outer diameter of 0.9mm cable is mainly used for stainless steel tube package PLC splitter, and 2mm and 3mm cable is mainly used for box-type optical splitter. Based on the difference of working wavelength, there are single window and double window PLC splitter. A single-mode fiber optic splitter and multimode fiber splitter.
