Fiber optics for SAT TV and DTT distribution


Fiber optic distribution of satellite TV offers such fundamental advantages like very low distribution losses and operation stability due to high immunity against external electromagnetic fields.
Signals of all four satellite sub-bands could be tailored into one thin fiber optic cable.
Possibility to use multi-fiber cables or add another optical carrier ensure highest flexibility and upgradeability of the installation.
Calculation of the system is really simple because no practically loss in fiber cables and no frequency dependence of RF parameters.
TERRA offers complete system for distribution over single mode fiber of DTT and SAT TV programs from single or several satellites.

excellent quality due to using of separated lasers for SAT and DTT content transmitting
standard quatro LNB could be used
 stability ensured by AGC system on transmitting site and OLC system on receiving site
 21 dB optical budget
