The utility model relates to a fiber communication's transmission reception device, including emitter and receiving arrangement, emitter includes host system, temperature detection module, modulation module, light source module and drive module, emitter is through fiber connection receiving arrangement, temperature detection module connects host system, host system connects the modulation module, light source module and drive module, it the problem that information is disorderly and can not regulate and control automatically appears to have solved current fiber communication effectively when carrier wave information is too much, think about ingenious and intelligent control, the singlechip U1 that the adoption model is AT89C52 is as microcontroller, each circuit module of emitter forms wholly, can realize the function of automatic regulation and control, application AT89C52's singlechip U1 control model CD4046's phase -locked loop chip J1, when carrier wave information is too much, information also can not be disorderly, receiving arrangement adopts the receiver tube as the demodulator, external output port, demodulation carrier wave information that can be fine, very big practical value and spreading value have.
