The invention discloses a split type electromagnetic shielding table cabinet which comprises an office table and a first electromagnetic shielding cabinet. The first electromagnetic shielding cabinetand the office table are in a split type. The first electromagnetic shielding cabinet comprises an electromagnetic shielding cabinet body and an electromagnetic shielding cabinet door; an optical fiber transceiver TX (optical fiber transmitter) is arranged in the electromagnetic shielding cabinet body, and an optical fiber waveguide tube is arranged on the electromagnetic shielding cabinet body. According to the split type electromagnetic shielding table cabinet, the optical fiber transceiver TX is arranged in the electromagnetic shielding cabinet; therefore, all signals can be connected onlyby connecting the optical fiber with an optical fiber transceiver RX outside the electromagnetic shielding cabinet during use, the electromagnetic shielding cabinet such as a computer host electromagnetic shielding cabinet does not need to be integrated with the office table, the occupied area is small, and use is more flexible and convenient.
