野战光端机

According to the demand for field operation of army, Sinotech Intellisoft launches the Field Intelligent multi service Optical Transmission Equipment. E1 signal, audio signal, telephone/magnet signal and line speed 100M Ethernet signal are multiplexed in STM-1 (155Mbit/s) fiber or E1 channels for transmission. IDM MTP-155 supports the transmission channel of STM-1 and E1 is intelligent mutual backup.
