5 Using the DVI Optical Transmitter/Receiver
You can use the 621T and 621R to configure a DVI optical transmitter and
receiver system as illustrated in Figure 5: the source connects to the 621T, the
621R connects to the display, and both transmitter and receiver are
interconnected via fiber optics and UTP cabling.

It is recommended to test your system configuration by first connecting the
entire system (as illustrated in Figure 5), using short copper cables instead of
optical fiber cables
5.1 Connecting the 621T/621R DVI Optical Transmitter/Receiver
To connect
1
the 621T DVI Optical Transmitter with the 621R DVI Optical
Receiver, as the example in Figure 6 illustrates, do the following:
1. Connect the DVI source (for example, a set top box
2
) to the 621T DVI IN
connector, using the DVI cable.
Make sure that the system is not powered up when connecting the DVI source.
2. On the 621R, connect the DVI OUT connector to the DVI acceptor (for
example, a display), using the DVI cable.
3. Remove the module dust covers and connect each duplex LC fiber cable
one-by-one to each of the four LC receptacles of the 621T and 621R.
4. Carefully recheck the polarities and ensure that the duplex connectors are fully
engaged.
Do not look directly into the LC receptacles of the 621T, while powered on,
although this product is regulated strictly enough to operate under the Laser
Class 1, classified by CDRH/FDA for eye safety
1 Switch OFF the power on each device before connecting it to your 621T and 621R. After connecting your 621T and 621R,
switch on its power and then switch on the power on each device
2 Alternatively, you could connect a computer or other DVI source
