Embodiment
Provide specific embodiment below in conjunction with accompanying drawing, how the integrated micro device ITW that further specifies the utility model realizes.
As shown in Figure 3, the integrated micro of the utility model is learned device ITW, comprises the first twin-core glass contact pin, 1, the first collimated light lens 2, isolator chipware 3, the second collimated light lens 4, the second twin-core glass contact pins 5, and set gradually by left-to-right; And interior envelope glass tube 6, metal external package pipe 7 sets gradually from inside to outside.
The described first twin-core glass contact pin 1 is as shown in Figure 4, comprises the first optical fiber 1-1, the second optical fiber 1-2, and the first twin-core kapillary 1-3, the first glass tube 1-4, first metal tail cover 1-5 forms.
Described isolator chipware 3 is by two vanadic acid yttrium angle of wedge sheets, faraday's revolving fragment, and a PMD compensating plate, a magnet ring is formed.Small-sized its effect of isolator chipware can make the light signal can only forward-propagating and the decay very big to the light signal generating of reverse transfer.
