Moreover, the provided module has advantages of simple structure and low manufacturing cost.
Description
Technical field
The utility model relates to a kind of dispersion compensation module.
Background technology
In optical communication, when a pulse is inputted from optical fiber, after the Optical Fiber Transmission through a segment length, the light pulse meeting of its output broadens, and obvious distortion has even been arranged, and this explanation optical fiber has the broadening effect to light pulse, and namely optical fiber exists dispersion.The dispersion of optical fiber is the main cause that causes that fiber broadband narrows down, fiber broadband narrow down can limit fibre transmission capacity, and optical fiber dispersion has limited the distance that signal can transmit, therefore chromatic dispersion problem is ubiquitous in the high-speed optical signal transmission, must there be dispersion compensation device in system, and system is carried out the transmission capacity that dispersion compensation can improve system effectively.
At present, in optical transmission system, the method for dispersion compensation can be used dispersion compensating fiber, Reverse Dispersion Fiber, but dispersion compensating fiber and mirror based fiber optica price are more expensive, and cost is higher.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, dispersion compensation module that cost is low.
To achieve these goals, the utility model is by the following technical solutions:
A kind of dispersion compensation module, be arranged between input optical fibre and output optical fibre, it comprises the glass matrix, is respectively equipped with on the two sides of described glass matrix to be linearly aligned etalon more than two, and is provided with between adjacent two etalons of homonymy to the inner isolation channel that extends of glass matrix; Etalon on the two sides of described glass matrix is crisscross arranged; Be equipped with conducting strip between described two above etalons and glass matrix, conducting strip is provided with thermistor and heating resistor.
Described glass matrix is 2, and 2 the sheet glass matrix is bonded to each other is integral.With two glass matrix composition dispersion compensation modules that are integral bonded to each other, good manufacturability, production efficiency are high.
The length of described glass matrix is 32 ~ 38mm; The width of described isolation channel is 0.1 ~ 0.3mm, and the degree of depth is 3 ~ 5mm, and the spacing of adjacent two isolation channels is 1.0 ~ 1.2mm.
The width of described etalon is 0.8 ~ 0.9mm.
Etalon on the two sides of described glass matrix is 8.
The utility model adopts above technical scheme, light signal after the etalon on the two sides of glass matrix carries out a series of reflections, thereby the dispersion of optical fiber is compensated, this dispersion compensation module is simple in structure, low cost of manufacture.
