Optical fiber communication network has become the cornerstone of today's information dissemination world. With the further development of the network and the increasing demand for communication bandwidth, the user's last ten kilometers and last kilometers of the entire communications network are using fiber. FTTH has become an important direction for the development of optical fiber communication network.
FTTH mainly uses PON network technology, which requires a large number of low-cost optical splitter and other optical passive devices. The optical splitter is part of the FTTH network. With the promotion of FTTH, the market demand will be even greater. From the perspective of optical device development can be seen, fiber PLC splitter has become a high-performance, low-cost optical splitter large-scale preparation of the mainstream technology. Through the production and optical fiber array package combined optical splitter chip, completed the optical splitter preparation, is the use of fiber PLC splitter. Its characteristics are small size, low cost, good uniformity of the spectroscope. But at the same time the technical threshold is relatively high, especially for mass production of large optical splitter production.
In the international arena, fiber PLC splitter has been widely used in small-scale, high-performance optical device manufacturing and production, especially optical splitter chip. However, in China, the actual situation is that we have become a PLC encapsulation power, but only limited to the PLC chip health line without optical splitter and optical device manufacturing equipment coupled package and downstream industry chain. While the PLC core device chip is completely dependent on imports. PLC equipment, the core preparation technology exists in the external problems, leading to equipment cost control, leading to high-end integrated chip development to further lack of technical support. This seriously hinders our development in PLC applications.
Today, a variety of fiber PLC splitter with optical splitter chips have different network connections in the market. The bare fiber splitter has no connector at the bare fiber end. The blockless PLC separator has a compact stainless steel tube package that provides a stronger fiber protection belt terminal.
