Model: LM-SF02LM-SF02LM-SF02
User Manual
Product Overview
LINK-MI LM-SF02 The HD/3G-SDI to fiber converter includes a
transmitter and receiver, which is a low cost transfer
device for unidirectional HD/3G-SDI video ,1ch 10/100M
ethernet and 1ch rs422 data over a single mode and
multimode optical fiber cable transfer. It is designed by
digital optical transfer technology and supports SMPTE292M
/SMPTE259M /SMPTE424 signal.
And the receiver can be put into a standard19” 3.5U rack
mount chassis,which support 16PCS receiver insert cards
with 2pcs 90~240V power supply.
