Background technology
Along with the proposition of " integration of three networks ", the fusion that how to realize telecommunications network, Broadcasting Cable Network, internet technically is a big problem that needs solution at present.
Before, telecommunications and broadcasting and TV all have network separately, and both are transferred to user side by circuit independently with service signal separately." integration of three networks " requires miscellaneous service to merge, and arrives user side by a transmission lines.
Optical Fiber Transmission becomes the first-selection of " integration of three networks " with the performance of its high capacity, two-forty, safety and stability, and miscellaneous service information can be by different optical wavelength transmission.Transmission when solving each wavelength, and be sent to different end respectively, just need a kind of new device to realize this function.
Closing glistening light of waves shunt is that the various wavelength signals of a kind of realization are fused to together, and the optical passive component that again the signal body of this burst fusion is transferred out by the optical power intensity of different weight percentage.It can solve professional converging in " integration of three networks " scheme, and is assigned to the technical task of different user sides.
Summary of the invention
Technical matters to be solved
The technical problem to be solved in the present invention provides the optical communication passive device of a kind of being used for " integration of three networks ", has different wave length and closes ripple, and will close ripple and close glistening light of waves shunt by luminous power percentage score multiple output function.
Technical scheme
The technical solution adopted for the present invention to solve the technical problems is: a kind of glistening light of waves shunt that closes is provided, and its waveguiding structure comprises WDM structure and light shunt structure.Described WDM structure is the wavelength division multiplexer of 1*M (M 〉=2), and the light shunt structure is fused tapered or the planar waveguide-type optical branching device of 1*N (N 〉=2), and wavelength division multiplexer and optical branching device form optical waveguide structure by the fusing mode combination.This waveguiding structure is packaged in the same box body, and input end exposes corresponding M road tail optical fiber, and output terminal exposes corresponding N road tail optical fiber.Described tail optical fiber diameter is Φ 0.9mm, Φ 2.0mm or Φ 3.0mm, can select tape FC/SC/LC/MU type connector.
