Abstract
The invention provides a light-splitting WDM device structure, comprising a double-fiber end optical fiber pigtail, a lens, a collimator, a glass tube, a sheath and a steel tube. The double-fiber end optical fiber pigtail and the lens are fixed through UV solidifying glue to form a reflecting end, and two end faces of the lens are plated with spectro-film layers. The reflecting end and the collimator are fixed in the glass tube through the UV solidifying glue. The reflecting end, the collimator and the glass tube are fixed in the steel tube through silica gel. Two ends of the steel tube are provided with the sheath. The reflecting end and a fiber of the collimator respectively extend from the sheath. Light-splitting WDM device structure is simple and reasonable, and has good light splitting effect. A filter is not needed since the spectro-film is plated on the lens, thereby reducing manufacture cost.
Description
Technical field
The present invention relates to optical-fibre communications field, relate in particular to the beam splitting type WDM device of optical-fibre communications field.
Background technology
Beam splitting type WDM (Wavelength Division Multiplexing, Wave division multiplexing) device has been widely used in the wavelength-division multiplex optical fiber communication system as one of primary element of optical passive component.Its effect is that perhaps the light of compound a plurality of wavelength transmits together with the separately transmission separately of light of a plurality of wavelength in the circuit.
Present beam splitting type WDM device adopts diaphragm type structure mostly; Optical fiber pigtail, lens and filter plate are adhesively fixed by the UV solidified glue; Device is directly through the filter plate beam split; Its defective is that the production cycle is long, raw materials cost is high, production efficiency is low, poor-performing, influences the normal use of product.
Summary of the invention
The object of the present invention is to provide a kind of when satisfying device reliability, simple in structure, with low cost beam splitting type WDM device architecture.
Technical scheme of the present invention is following:
A kind of beam splitting type WDM device architecture comprises two fine end optical fiber pigtails, lens, collimating apparatus, glass tube, sheath and steel pipe; Said two fine end optical fiber pigtail and lens are fixed through the UV solidified glue, form reflection end, and the both ends of the surface of lens are coated with spectro film; Said reflection end and collimating apparatus are fixed in the glass tube through the UV solidified glue, and in steel pipe, the two ends of steel pipe are equipped with sheath through silica stationary for said reflection end, collimating apparatus and glass tube, and the optical fiber of said reflection end and collimating apparatus stretches out from sheath respectively.
Useful technique effect of the present invention is:
The present invention is simple and reasonable for structure, and spectrophotometric result is good.Through on lens, plating spectro-film, avoided the use of filter plate, thereby reduced manufacturing cost.
Description of drawings
Fig. 1 is a cut-open view of the present invention.
Fig. 2 is an outside drawing of the present invention.
Embodiment
Further specify below in conjunction with the accompanying drawing specific embodiments of the invention.
Like Fig. 1, shown in Figure 2, the present invention is made up of two fine end optical fiber pigtails 1, lens 2, collimating apparatus 3, glass tube 4, sheath 5 and steel pipe 6.Two fine end optical fiber pigtails 1 and lens 2 are through the UV solidified glue formation reflection end that is fixed together.The both ends of the surface of lens 2 are coated with spectro film (the black part of lens 2 right ends among Fig. 1).With UV solidified glue fixation reflex end, collimating apparatus 3 and glass tube 4.Then with above-mentioned total with silica stationary in steel pipe 6, at the two ends of steel pipe 6 sheath 5 is installed, reflection end and collimating apparatus are stretched out optical fiber by the two ends sheath respectively, formation light inlet and bright dipping end.Spectro-film is those skilled in the art's a known products, in the present embodiment, accomplishes the work of plating spectro film by Fujian photoelectricity company limited.
Above-described only is preferred implementation of the present invention, the invention is not restricted to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from basic design of the present invention, all should think to be included within protection scope of the present invention.
