- DVOP-VE-AI08 8 Lu Aifeng intercom optical terminal
-
DVOP-VE-AI08 is an 8-way Aifeng intercom dedicated optical terminal with complete core intellectual property rights of Guangxiang. It can transmit up to 16 channels of Aifeng intercom signals on a single fiber. Through unique voltage, signaling and audio demultiplexing technology, it can convert Aifeng analog intercom signals into optical signals in real-time, synchronous, distortion-free and high-quality transmission. Without making any changes to the Aifeng intercom host and extension, it can adaptively identify and be compatible with the audio and control protocols of the three series of Aifeng LEF, NEM and LEM, and can achieve all functions of the three series of Aifeng stably and reliably. DVOP-VE-AI08 is specially designed for the harsh environment of lightning, surge, electrostatic ESD, the use of bridge multi-level protection makes the equipment can operate stably and reliably in the environment of strong electric field, and realizes the all-round protection treatment of all external ports of the equipment telephone, audio, data, network, alarm volume, power supply, etc., reaching the three-level lightning protection standard.
DVOP-VE-AI08 optical terminal support centralized management card application, support network management function, can be seamlessly connected to our centralized management platform e-MS, support remote and local computer integrated transmission system network management function, open interface design allows integration into a higher level of network management system.
