Product Description




SFP 10/100/1000M Fiber Media Converter



JYT-GS803 series Gigabit Ethernet SFP fiber media converters bridge the gap between copper and fiber infrastructures. The SFP fiber media converters are designed for maximum convenience for fiber to copper Ethernet conversion applications which require flexibility in transmission rates, working distances, and fiber network types which can be realized by simply changing the hot-plug-and-play SFPs.


· Telecommunication Networks

· Schools, Offices, CyberBars



· High flexibility with hot plug-and-play SFP

· 1600byte super data packet transmission

· Full duplex-flow control, Half duplex-back pressure

· Link fault pass through (LFPT)

· Full- positioned LEDs to indicate power and network status
