Distribution, Optical, 1208/9A


The ptf 1208A (transmitter) and ptf 1209A (receiver) provide a convenient and simple way to transmit high quality RF signals over long distances, without the concerns associated with electrical interference and pick-up.
The ptf 1208A accepts an RF input in the range from 1kHz up to greater than 10MHz and provides a combination of 8 local, high isolation, RF distribution outputs and 4 optical transmission outputs for distances up to 2 kilometers.
The ptf 1209A accepts an optical input (transmitted from the ptf 1208A) and provides 12 local RF outputs, either digital (TTL into 50 ohms) or low noise sine wave signals driving 1V rms into 50 ohms (with the PLL option), or both.
These systems are especially designed to accommodate IRIG B DCLS, 1PPS and other RF signals in the range from 1kHz to 20MHz.
The modular construction allows for a variety of input/output configurations to provide a fully tailored application solution.
