Abstract
The present invention relates to a 1*N plastic optical fiber coupler which comprises a main plastic optical fiber and N branch plastic optical fibers, wherein N is a natural number greater than 2. The main plastic optical fiber is connected with the N branch plastic optical fibers through a funnel-shaped waveguide member. The plastic optical fiber coupler has the advantages of uniform light splitting ratio, low insertion loss, simple structure and low preparation cost, and is suitably used as a wave separator or a wave synthesizer in plastic optical fiber networks.
Description
Technical field:
The present invention relates to a kind of fiber coupler, particularly a kind of suitable 1 * N plastic optical fibre coupler of making channel-splitting filter in the plastic optical fiber network or wave multiplexer.
Technical background:
In recent years, plastic optical fiber has become the domestic and international research focus as the transmission medium of broadband LAN, and plastic optical fiber is expected to compete mutually with cable and silica fibre with significant ratio of performance to price advantage, thereby becomes a kind of main transmission medium of high-speed local area network.Because installation cost occupies quite great proportion in the LAN (Local Area Network) total cost, plastic optical fiber will be obtained significant ratio of performance to price advantage in connecting intensive LAN (Local Area Network), need the joints of optical fibre and the coupling mechanism of a large amount of high performance price ratios.
The mixing rod legal system is equipped with plastic optical fibre coupler and has advantages such as simple in structure, easy to make, with low cost.Present employing mixing rod method cost has been prepared N * N, 1 * N plastic optical fibre coupler.There is the splitting ratio lack of homogeneity in these coupling mechanisms, insert the big shortcoming of loss.
Summary of the invention:
The object of the present invention is to provide a kind of low-cost preparation splitting ratio even, insert the low 1 * N plastic optical fibre coupler of loss.
For achieving the above object, the present invention adopts following proposal:
A kind of 1 * N plastic optical fibre coupler comprises main plastic optical fiber (1) and N branch's plastic optical fiber (2), and N is greater than 2 natural numbers, it is characterized in that main plastic optical fiber (1) is connected with N branch's plastic optical fiber (2) by an infundibulate wave guide member (3).The circular end surface (3-2) of above-mentioned infundibulate wave guide member (3) is connected with main plastic optical fiber (1), and the axis of main plastic optical fiber (1) overlaps in line with hopper centre's line of infundibulate wave guide member (3); The annular large end face (3-1) of infundibulate wave guide member (3) is connected with the face of tiltedly carving of N branch's plastic optical fiber (2), and the axis of each branch's plastic optical fiber (2) is paralleled with the funnel bus of infundibulate wave guide member (3).Above-mentioned infundibulate wave guide member (3) is mutually bonding with main plastic optical fiber (1) and branch's plastic optical fiber (2) respectively by the refractive index glue that is complementary.The interior lateral surface of above-mentioned infundibulate wave guide member (3) is coated with the metal film (4) of high reflectance.
The present invention compared with prior art, have following conspicuous outstanding remarkable advantage: 1 * N plastic optical fibre coupler splitting ratio of this aspect is even, and the insertion loss is low, simple in structure, preparation cost is low, is fit to do channel-splitting filter or wave multiplexer in the plastic optical fiber network.
