4-CH Digital Video Converter/Transmitter

4-CH Digital Video Converter/Transmitter
Product Detailed
Video Converter/Transmitter all-digitally&non-compressingly transmit 4-CH videos in 1-core fiber; CE, FCC, RoHS.

Video Converter/Transmitter


CY-9804 series Digital Video Optical Converter is used for real-time, high-resolution, long-distance and non-distorted transmission of 4-channel video signals in one-core fiber.


1. Automatically adapt to data rate, without setting;

2. Automatically compatible to PAL, NTSC, SECAM systems;

3. APC circuits support constant output optical power and wide Dynamic Range;

4. No inter-modulate interference problem in other optical converters of non-simulate frequency modulation, phase modulation, amplitude modulation;

5. Technical grade modulation design makes it easier to expand the functions;

6. Unique 3-level surge protection design for High voltage, Low voltage, and static;

7. Power supply with AC 220V, DC-48V, 24V, 12V, 6V, 5V available, and low power consumption;

8. Stand-alone unit and 1U/2U/4U rack mount available;

9. High stability, without on-site electrical and optical adjustment;

10. Specially designed matching circuit of optical module, with low heat emission;

11. With TDM, ADM, and CWDM techniques, especially applicable for the environment not suitable for wiring.
