Optical transmitter OT301
Optical receivers OR301, OR301M
Product description
The optical transmitters series OT and the optical receivers series OR are intended to distribute SAT IF and DTT (Digital
terrestrial TV) signals through a fibre optic.
The transmitter OT301 converts 2 SAT IF sub-bands and DTT band into an optical signals.
AGC (automatic gain control) provides for automatically controlled constant RF level to the laser.
The receivers OR301, OR301M convert optical signals into 2 SAT IF sub-bands and DTT band.
OLC (optical level control) provides for fixed RF output level at different level of optical input.
Receiver with letter M (OR301M) have built-in multiswitch (quad outputs).
The product is intended for indoor usage only.
