2.11 Optical Signal Output Board (Optional)
The optical signal output is performed by GPA-325 (Figure 2-2) paired with the optical signal
output interface board GFA-340 (Figure 2-11) jointly. GFA-340 can be placed at any one of the
first 4 slots from the left at the back of the product (see Figure 1-4). In practical application, the
optical signal output board sshould be used together with a DVI to optical-fiber receiver (similar
as the transmitter, see Figure 2-10).
Fig.2-11 GFA-340
The specific functions of GFA-340 are as follows:
The long-distance DVI signal transmission can be realized with a single-core and
multi-mode optical fiber cable and the maximum transmission distance can be 300m;
The transmission speed is 4.5Gbps;
Support a HDMI video resolution up to 1080p@60Hz 24-bit color depth;
Meet the requirement on reliability of optical module: TELCORDIAGR-468;
Real plug and play, no manual EDID setting is required;
Signal re-clocking, no TMDS extension, so as to reduce clock deviation;
No RFI/EMI radiation or video quality attenuation, ensuring data security.
