Product description:

OT1 / 1FEC is a converter of terrestrial and satellite TV and radio RF electrical signals for transmission via optical fiber (optical transmitter).
Power supply is possible via a DC connector.
The transmitter is intended for use with single-mode optical fiber (“Singlemode”).
When connecting the optical transmitter and optical receiver directly over a shorter distance without optical attenuation (eg an optical splitter), we recommend inserting at least 3 dB SC/APC optical attenuation between them.
