视频光Multiplexer(8频道）

The Video opticalMultiplexer(Vispace 4000 series) which is from Visint Communication Technology Co.,Ltd can reach thebrocast-level standard, and the audio quality can be CD-level. It supports the digital communication mode such as RS-232, Rs-422, RS-485(2/4line). Manchester code., etc. and connection with Ethernet. Through DIP switch, the data mode atinput port can be different from that at output port. Telephone signal can transmit directly through special telephone transmission module.It has function of dust-proof, smog-proof, anti-mist,etc. guarantees the high-reliable operating under the horible environment. the plug-and-play desigh makes installation much more convenient.There is no need for any optical or electric modulation. All the instruction LEDprovides quick system diagnose function. Functional Features: 1. All the transmission takes in only one fiber with non-compression data transmission 2. The MAX 64-channel video transmits data in real time, and the video SNR is ≥70dB. 3. The video transmission standard is above the EIA RS-250C short-distance video transmission requirement. 4. It can be compliant with the video format which CCIR allows such as PAL, NTSC and SECAM simultaneously. 5. It supports the data communication format such as: RS-232, RS-422, RS-485(2/4line), Manchester code, etc. 6. The Ethernet and telephone signal can transmit simultaneously and supports network management. 7. The MAX transmission distance without trunk can be 120km.(can add trunk site) 8. Without electromagnetism interference, emitting frequency interference or ground current. 9. The video, audio, data, and Ethernet ports have lighting protection function. 10. It has the identification function, and is confidential to prevent illegal filching video. 11. It is plug-and-play and supports hot-swap, convenient for fixing without modulation.
