超低速的光纤一体发接收发送器,同于以前的光纤一体化接头都只适用于2M以上的通讯,如需将232等低速信号用光纤传输出,需要加复杂的调制解调电路,网动光电新生产的这款光纤头主要针对低速信号,可以传送DC-500KPS的信号,极大地简化了硬件设计.(Ultra-low-fat whole-speed fiber-optic transmitter receiver with fiber-optic integration in the previous joint only applies to more than 2M communications, etc. For the 232 low-speed optical fiber transmission of signals, the need to increase the complexity of the modulation and demodulation circuit, the net move Photoelectric new production of this first major response to low-speed fiber-optic signal, DC-500KPS can send the signal, greatly simplifying the hardware design.)
