The present invention is directed to a Fiber Selective Control Switch system for simulating human intervention during a test process for fiber network environments. The Fiber Selective Control Switch system may comprise a MCU, and at least one FSCS module mounted on a SFP device. The MCU is download programmable with basic code, which remotely controls FSCS modules. Each FSCS module coupled to the MCU may include two MOSFETs and a pull down resistor. A positive signal voltage from the MCU to the FSCS module mounted on SFP device will disconnect the fiber connection. A low signal voltage from the MCU to the FSCS module will re-connect the fiber connection. Advantageously, the FSCS system may not affect normal fiber operations due to fast switching characteristics of MOSFET devices and the MCU's low power requirement.
