tEnclosure box material is made of aluminum, elegant appearance, light weight
tPCB boards made with environment friendly pb-free and RoHS compliant
tConvenient instructions of LED status, video/audio activity, optical link, power supply etc.

Introduction
tDoteck A4 series is high performance digital fiber optic transmission system. The transmitter input 4-channel composite analog video and 8-channel analog audio. The receiver output 4-channel composite analog video and 8-channel analog audio.
tThe quality of video, audio non-compressed transmission with digital designs is much superior to the analog transmission based on amplitude frequency modulation designs.
tDue to the advanced digital fiber optic transmission technology, almost you need not make any adjustments, simple to set up, easy to operate.
