§1.1 Introduction EB-DV series digital fiber multiplexer (Fiber mux for short) is complete digital high speed fiber transmission product. Using advanced fiber communication technology, digital video technology and data communication technology and adopting reliable large scale special integrated circuit and whole surface by decoration, it is one of the most advanced transmission product for long-distance and high- fidelity video monitoring at present. This product is made up of fiber transmitter and fiber receiver and can transmit 16 channels broadcasting positive video signal, 1 channel high-speed positive and negative asynchronous data signal. §1.2 Characteristics ² ASIC design SMT craftwork ² Complete digital fiber transmission platform and flexible configuration of different signal ² Two types: standalone, desktop; card, rack ² Independent intellectual property large-scale special-purpose integrated circuit core ² Transmit on one fiber, double fibers is also selected. ² PAL/NTSC/SECAM auto-negotiation, broadcasting transmission quality ² Provides bi-directional asynchronous data (positive and negative) ² Provides one channel asynchronous data, the transmit speed can reach more than 115.200Kbps. ² Asynchronous data are RS232/RS485/RS422/ Manchester code. §1.3 Technical Specification Optic fiber Connector: FC Transmission range: 0~120Km (single-mode fiber, for option) 0~2Km (multi-mode fiber, for option) Note: Transmission range is affected by loss of optic fiber and other index, so the actual range may be different from the above data.
