Optical SAT distribution

The distribution of satellite signals via fiber optic cables offers technical and economic advantages, especially for larger distances / distribution networks and a large variety of programmes. In addition to the high data capacity and the almost loss-free signal transmission, the quick installation and reliability of pre-assembled fiber optic cables play a decisive role.

The POLYTRON system with CWDM technique

TThe optical transmission system from POLYTRON is based on a Sat-IF / optic converter and optic / Sat-IF converters. The satellite signals are received via a conventional Quad or Quattro LNB.
The optical system from POLYTRON uses the proven CWDM technology for the transmission of the SAT IF levels. Each SAT IF level is assigned a fixed optical wavelength and the signal is made available at an optical output.

The fixed assignment of the individual levels allows to distribute signals without frequency shift in the SAT IF levels, especially in frequency ranges above 2000 MHz that are difficult to control.
All components of the POLYTRON system are equipped with SC / APC connections. This means that the preconfigured patch cables and passive distribution components can be installed quickly and easily.
As the system works with conventional LNBs, it is easy to convert existing systems to optical systems.

Quattro and Quad LNB compatible

The OT 9-5 CWDM transmitter is used to receive signals in the 47–2150 MHz range and convert them into optical signals in the 1330–1390 nm and 1510–1570 nm range, which can then be fed into an optical distribution network.

Eingebautes CWDM Technologie mit DFB Laser 

The OT 5-5 CWDM optical transmitter is used to receive 4 SAT input signals and terrestrial signals and convert them into an optical signal. The input signals are assigned to separate wavelengths in the range 1510 ... 1570 nm. 

Bandwidth CATV 47 to 862 MHz and SAT IF 950 to 2150 MHz

The mini transmitters of the AOT126 series transmit both SAT IF and CATV signals via optical cables. They represent a cost-effective solution and impress with their excellent performance.

Compact design and low power consumption

The mini transmitters of the AOT126 series transmit both SAT IF and CATV signals via optical cables. They represent a cost-effective solution and impress with their excellent performance.

Zum Anschluss von Multischalter-Systemen. Quattro or quad LNBs can be connected. 

The OR 5 QT II and OR 4 S II optical receivers are used to reconvert the optical signal into the SAT and terrestrial signals in the RF range. 

High return loss and linearity

The OR 9 QT optical receiver converts the received optical signal into an RF signal and outputs it to eight outputs with fixed SAT polarization planes and one terrestrial output for connecting multiswitch devices.

For direct connection of receivers/TV sets

The OR 5 QT II and OR 4 S II optical receivers are used to convert the optical signal back into the SAT and terrestrial signal in the HF range.
