The DGX-I-DXF-MMD is a DXLink Fiber input board with field serviceable SFP modules designed for use with multimode fiber, and is compatible with the Enova DGX 8, 16, 32 and 64 Digital Media Switcher Enclosures. Use it as part of an integrated system to receive audio, video, control and Ethernet over multimode fiber from up to 300 meters from a DXLink Transmitter. Fiber uses light to send data, rather than electric signals making it both the highest quality and most secure way to transmit video as it is not susceptible to electronic noise or non-intrusive physical wiretapping.
