With the advent of 4K/UHD television, distribution of higher data rate video signals up to 11.88 Gb/s (12G-SDI) has become necessary which can't
always be achieved via coaxial cable. |
NOTE: |
1 |
16 dB path loss at HD/SD, 15 dB at 3G and 12 dB at 12G/6G. Fitted with PIN detector. |
2 |
When operating as a pair, one IRT-6642-DTR must be fitted with a 1510nm/1550nm transceiver pair and
the other with a 1530nm/1570nm transceiver pair. |
