Abstract

A planar optical waveguide splitter applied to a Fibre To The Home (FTTH) system is disclosed. The splitter is mainly composed of a housing (1), a single input optical fibre (2) and an output optical fibre array (3). The single input optical fibre (2) and the output optical fibre array (3) are located on the same side of the housing (1). A 1*N type optical waveguide chip (4) is arranged in the housing (1). The single input optical fibre (2) is connected to the input end of the 1*N type optical waveguide chip (4), while the output optical fibre array (3) is connected to the output end of the 1*N type optical waveguide chip (4). The splitter disclosed by the invention is capable of splitting one branch of optical signal into 64 branches of optical signals at most, thereby solving the problem of FTTH of 64 families simultaneously. By employing the planar optical waveguide splitter, the network construction cost can be greatly reduced and the use cost of each user is reduced; and meanwhile, more network bandwidth can be provided for the users so that the user can enjoy more network resources.

Description

technical field [0001] The invention relates to an optical waveguide splitter, in particular to a planar optical waveguide splitter applied to an FTTH system. Background technique [0002] Fiber to the home, also known as FTTH (Fiber to The Home), refers to the installation of optical network units at home or business users. The remarkable technical feature of FTTH is that it not only provides greater bandwidth, but also enhances the transparency of the network to data format, rate, wavelength and protocol, relaxes the requirements for environmental conditions and power supply, and simplifies installation, use and maintenance. [0003] People's demand for multimedia applications such as distance education, telemedicine, and video conferencing has increased significantly, and e-commerce is a typical hot spot of network applications. At the same time, people have put forward higher requirements for network bandwidth and speed, prompting the rapid development of the network fr...
