Terra OT401 Manual

Optical transmitters OT401, OT501W
Optical receivers OR401, OR401M, OR501W, OR501MW
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.
Transmitters series OT4 convert 4 SAT IF sub-bands into an optical signal.
Transmitters series OT5 convert 4 SAT IF sub-bands and DTT band into an optical signals; for converting SAT and DTT bands separate lasers are used. To combine two
optical cariers into one single-mode fibre WDM diplexer is used.
AGC (automatic gain control) provides for automatically controlled constant RF level to the laser.
Receivers series OR4 convert optical signal into 4 SAT IF sub-bands.
Receivers series OR5 convert optical signals into 4 SAT IF sub-bands and DTT band; for converting SAT and DTT bands separate photodiodes and WDM diplexer are used.
OLC (optical level control) provides for fixed RF output level at different level of optical input.
Receivers with letter M (OR401M, OR501MW) have built-in multiswitch (quad outputs).
The product is intended for indoor usage only.
