Ethernet Media Converter
This Ethernet Media Converter is an all-digital fiber transmission device,with world class non-compression, all digital video correction technology and Gigabit fiber transmission technology. It can transmit long distance, non-distortion and real-time 1~64 channels of video signal (or data, audio, Ethernet, alarm, phone if necessary) by one-core fiber.
Features
1.Uncompressed 8 bit video and 24bit audio encoding, High-speed synchronous digital transmission technology.
2. Fiber optic transmission of four video signals on one fiber with RS485,RS232 and RS422 data
3. signals(three of each)which may be one way with the video or optionally duplex.
4. Super optical dynamic range, no adjustment needed
5. Status indication for power supply, optical signal and video
6. No electromagnetic interference, radio frequency interference and ground current
7.Safe transmission guaranteed under poor electromagnetic environment
8. Maximum tolerable link loss for single mode single fiber is 18db
9. Range of up to 100km is possible with optional 1550nm operation
10. Optional duplex operation over one fiber
Application
1.CCTV networks
2.video conferencing
3.Industrial monitoring systems
4.Distance learning
