Function
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 ( and other kinds of signals when they are needed) in one-core fiber.
Features
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.
