Abstract:
An optical circuit module comprising:optical signal emitting means for emitting an optical signal; a first sleeve, which includes a first end surface; an optical device, which includes a reflection surface, wherein the reflection surface abuts against the first end surface of the sleeve; a first lens located between the optical signal emitting means and the optical device, wherein the first lens converts the optical signal emitted from the optical signal emitting means into a collimated optical signal and emits the collimated optical signal to the optical device, wherein the optical device reflects the collimated optical signal with the reflection surface, and the first lens converges the reflected collimated optical signal and generates a converged light signal; and optical signal receiving means for receiving the converged light signal, wherein the first lens is fixed in the first sleeve such that the focal point of the lens aligns with the reflection surface of the optical device, and wherein the optical signal emitting means and the optical signal receiving means are fixed in the first sleeve such that the converged light signal is coupled into the optical signal receiving means.
