■ Product introduction:

CJ series Digital Fiber Optical multiplexers were independent developed by CJ-LINK, using advanced large scale programmable circuit and total digital uncompressed technology, with high performance special design for small scale fiber transmission of video, audio, data, Ethernet and switching simultaneously; High integration and stability, low power consumption, high adaptive capacity, total surface decoration and simple structure satisfy customer various demands in many occasions.
■ Product Characteristics:

◆Industrial design, SMT craftwork.
◆1.5Gbit/s complete digital fiber transmission platform, Multi- Service and flexible configuration.
◆Standalone, chassis for option.
◆Single fiber transmission, optional for double fiber.
◆PAL/NTSC/SECAM all compatible, carrier-grade quality
◆Dynamic indication of operating status
◆Field deployment without adjustment.
◆Auto reset function more stable.
