State of the art in satellite fibre optics transmission

TOFsat is the scalable system for reception and passthrough transmission of satellite and terrestrial broadcast services distributed over a Fibre Optic (FO) network, to a virtually unlimited number of homes.

It is intended to be used in multi-dwellings or multiple service FO networks.

The TOFsat advantage

Fibre cabling has some significant advantages compared to coax cabling in general:
  • Higher bandwidth — a 3mm fibre cable substitutes 5x7mm coax drop cables for transmission of the full bandwidth for one Sat position and the terrestrial signals
  • Allows enlarged cabling distances because of the low attenuation of a fibre cable – about 0.35dB per 1 km
  • Prevention of electromagnetic ingress noise from LTE mobile services, for example, and disturbance from DC potential and transient currents because of the natural galvanic isolation of fibre cables
High flexibility
  • Reception of the vertical and horizontal polarised frequency ranges of a satellite position, plus terrestrial FM, DAB and DTT bands over one mutual fibre line
  • Optional use of different LNBs: Standard wideband LNB, K-band LNB or dCSS LNBs for operator-specific satellite programme bouquets
  • Enlargement of the FO networks by active FO Repeaters or EDFAs
Cost saving
  •  TOFsat is highly competitive because it uses frequency stacking and de-stacking for the Sat-IF-High, -Low and TER bands using specific ASIC chips. Thus only one laser transmitter and one optical receiver is sufficient for one entire Sat position and terrestrial transmission. (Comparing frequently-used wavelengths multiplexing in alternative systems needs 3 laser transmitters and 3 optical receivers in the re-converter for the same constellation. This increases the cost on the reception side, especially if large numbers of re-converters are connected.)
  • FO networks require less maintenance effort, and also less power consumption.
