Satellite signal distribution via fibre optic cable

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.

Optical receiver for 4 subscribers - type OR 4 S

The OR 4 S optical receiver converts the incoming optical signal for direct connection of upt to four receivers or TV sets.
The subscribers can receive all programmes with a standard digital receiver or TV set with an built-in digital tuner. It is irrelevant whether the individual programs are broadcast in HDTV, as pay TV or as free-to-air signals.


4 subscribers resp. devices

Optical Receiver for Multiswitch systems - type OR 5 QT

The OR 5 QT optical receiver converts the incoming optical signal back into the four SAT polarization levels and a terrestrial signal.
The output signals can be fed into multiswitch distribution systems or headends.

  • Conversion of the optical signal without quality loss
  • For connection to a multiswitch system
  • Built-in CWDM
  • Power supply with 20 VDC
  • SC/APC connector
  • Delivered with power supply



Multiswitch system

OPM-QTS optical converter QUATTRO

POLYTRON OPM-QTSThe con­verter OPM-QTS is a terminal station of the fibre-optic network which converts the light-wave signal back into the original satellite signal with terrestrial signal.

The OPM-QTS quattro converter gives out the four sat levels:  HH, VH, HL, VL and a terrestrial signal, which allows for the direct connection to a multiswitch system.

CATV and SAT IF Mini Node

The mini receiver of the AON126 series receives optical signals and delivers both SAT IF and CATV signals at the output.

CATV and SAT IF mini transmitters

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

Optical splitters OSF ... SC/APC

The splitters OSF ... SC/APC split an optical signal to 2, 3, 4 or 8 outputs. Each connection is equipped with a SC/APC socket. The incoming and outgoing optical cables can be connected directly to the splitter avoiding faults and needless couplings.

Asymmetric 2 way splitters

The splitters OSF ... SC/APC split the optical signal asymmetrical to 2 outputs. Each connection is equipped with a SC/APC socket. The incoming and outgoing optical cables can be connected directly to the splitter avoiding faults and needless couplings.
