Simultaneously transmit up to two discrete 12G-SDI signals over single mode fiber cable with the Freakshow HD 12G-SDI Dual SDI to Fiber Transmitter with Locking Power Connector. This low-power consumption transmitter features a LEMO power connector to help avoid accidental pull-outs. The transmitter re-clocks the BNC SDI inputs and converts the signal to fiber, transmitting it up to 6.2 miles. You will need a receiver at the other end to decode the fiber signal and output SDI video.
