Description
Technical field
The utility model relates to full glass matrix dense wave division multiplexer, it adopts the Thin Film Filter technology, can carry out multiplexing to a plurality of ITU channels, can select arbitrarily C-band and L-band operation wavelength, have low insertion loss, low PDL, high-isolation, high stability, high reliability, the wide characteristics of bandwidth.
Background technology
Along with developing rapidly of data communication, particularly Internet fast development, bring the Internet traffic carrying capacity to be explosive increase, therefore more and more higher to the wide demand of transfer of data guipure.At present, existing optical fiber telecommunications line its use that clearly is nowhere near.Yet, lay the cost that optical fiber telecommunications line has not only increased communication again, and take the material effort.
Though at present many manufacturers have developed and have begun to have produced some dense wave division multiplexer kinds, but existing dense wave division multiplexer has used glass and metal mixed matrix, temperature consistency to product exerts an influence like this, and unfailing performance can not guarantee.
Summary of the invention
The purpose of this utility model provides a kind of full glass matrix dense wave division multiplexer at above-mentioned weak point, this dense wave division multiplexer adopts full glass matrix, so, entire device is in full glass matrix state, avoided thermal coefficient of expansion between the different materials different and influence the problem of device performance, thereby improved stability and the reliability of product, also reduced production cost of products simultaneously temperature.
Full glass matrix dense wave division multiplexer is to take following mode to realize: full glass matrix dense wave division multiplexer structure mainly is made up of Thin Film Filter, double-fiber collimator, single fiber collimater and glass bushing.Thin Film Filter is adhesive on the double-fiber collimator, and the double-fiber collimator and the single fiber collimater that are pasted with Thin Film Filter are sleeved in the glass bushing, and the gluing one that is packaged into constitutes full glass matrix dense wave division multiplexer individual devices.
Thin Film Filter is bonded on the double-fiber collimator with glue, to post the filter double-fiber collimator and the single fiber collimater is separately fixed on the support, regulate backing positions, with two collimaters to light, make the transmission light value maximum as far as possible, put glass bushing, glass bushing and two collimaters are sticked together with glue.
Several full glass matrix dense wave division multiplexer individual devices series connection fixed sealing are contained in and constitute the multichannel dense wave division multiplexer in the glass matrix draw-in groove module.
Full glass matrix dense wave division multiplexer key technology is at the Thin Film Filter superior with it, Thin Film Filter is the deielectric-coating of the different materials, different refractivity and the different-thickness that are combined by designing requirement by layer up to a hundred, every layer thickness is 1/4 wavelength, one deck is a high index of refraction, and one deck is that low-refraction is superimposed and forms.When light incided high refracting layer, reverberation did not have phase shift, when light incides forming low-refractive-index layer, and the 180 degree phase shifts of reverberation experience.Because bed thickness 1/4 wavelength, thus after the light experience 360 of low refraction is spent phase shifts with the reverberation of high refractive index layer with superimposed.Near centre wavelength, the stack of each layer reverberation forms very strong reverberation at the filter end face like this.Outside this high-reflection region, reverberation reduces suddenly, and most of light becomes transmitted light.Adopt the DWDM diaphragm of unique film system design, Insertion Loss, flatness, pass band width, the equal approximation theory limit of cut off band width, thus undershoot decreases, the dense wave division multiplexer spare and the module of high-isolation are laid a good foundation in order to produce.
Full glass matrix dense wave division multiplexer characteristics:
1, full glass matrix dense wave division multiplexer is in full vitreousness, has avoided thermal coefficient of expansion between the different materials different and influence the problem of device performance, thereby has improved stability and the reliability of product to temperature.
2, change metal material into glass material, reduced production cost of products.
3, simplify production technology, enhance productivity.
