Light reflection that adjustable mirror can transmit first lens is stated to first lens or the second lens；It is described adjustable anti-
When penetrating mirror and being in first angle, described first is incident to thoroughly after the first collimating mirror of optical signals collimation of first optical fiber output
Mirror is reflected back first lens, then collimate via described first after first lens via the adjustable mirror
After mirror collimation, from second optical fiber output；When the adjustable mirror is in second angle, the light of first optical fiber output
Signal is incident to first lens after being collimated by the first collimating mirror, after first lens, via the regulating reflection
Mirror reflexes to second lens, then after being collimated via second collimating mirror, from the third optical fiber output.
Preferably, further include MEMS chip, the adjustable mirror overturns the energized state for passing through the MEMS chip
It is controlled, when the MEMS chip powers off, the adjustable mirror is in first angle；When the MEMS chip is powered
When, the adjustable mirror is in second angle.
Preferably, when the adjustable mirror is in first angle, the adjustable mirror and horizontal plane are perpendicular.
Preferably, first collimating mirror have the first substrate, first substrate for fix first optical fiber and
Second optical fiber, first optical fiber and the second optical fiber central symmetry in first substrate arrange；The second collimation utensil
There is the second substrate, second substrate is for fixing the third optical fiber.
The utility model has the beneficial effects that：The case where being different from the prior art, the utility model pass through adjustable mirror
Light letter is realized in the transmission path of switching optical path, the same side that the first collimating mirror and the second collimating mirror are set to adjustable mirror
Number output and input, thus reduce the volume of photoswitch, it is poor so as to solve performance, volume is big, be difficult to encapsulate and
Problem not easy of integration.Adjustable mirror is at first angle after photoswitch power down, and optical signal can be from output optical fibre
Middle output, follow-up system will not paralyse completely.
