Product description
The Optical Transmitter is the core component on the headend side of the TOF (Triax Optical Fibre)
system. This plug-and-play optical headend unit converts RF Wideband or Quattro SAT-IF and
terrestrial FM, DAB, DVB-T or CATV signals to multiple optical wavelengths for transmission over a
PON (Passive Optical Network). The TOST Optical Sat Transmitter uses two DFB lasers of wavelength
1310 and 1330nm for the V and H SAT-IF wide-bands. The TOCT Optical Combined Transmitter
additionally has built-in a 1550nm laser for the CATV or terrestrial signals.
The optimal quality of the output signal is processed by Automatic Gain Control (AGC) and
Automatic Slope Control (ASC) and enables the transmitter to drive up to 64 optical splits to
the optical re-converters TDC 3 or 4
Up to 128 splits are possible when using the wideband optical receivers TWOC and TWCT.
Terrestrial antennas connected to the “C” (CATV/TERR) input of the TOCT must be connected
via a 4G filtered, selective pre-amplifier like the TMB 2500UK (360238).
