Triax TVC 04 virtual quad converter.
Converts the optical signal from an opticalLNB to 4 (quad) electrical outputs (the same as a quad LNB)

Optical LNBs are needed for long cable runs. If the cable run is over 70m an optical LNB may be needed.An optical fibre cable connects to the LNB and this can go direct to this interface or it can be split using optical splitters.Either way it must connect to an optical to electrical interface (called a Virtual Converter")and there are two types. This one has a quad output (the same as a quad LNB).The other type (below) has a quatro output (same as a quatro LNB). The quad output can feed 4 single tuner satellitereceivers or two twin tuner satellite receivers. The quatro interface ("Virtual Quatro Converter") below feeds intoa multiswitch and then as many outputs as are needed can then be provided by the correct multiswitch.Multiswitches can have up to 48 outputs but more than one multiswitch can be used if more than 48 outputsare required. Optical fibre cable is difficult toterminate without the correct tool and so it is best to order pre-made optical cableswith the connectors already fitted. Make sure the pre-made cable is long enough for thejob! Too long is not a problem as there is zero loss. It is also possible to overload the electrical interface and so anoptical attenuator should be fitted. This is needed if only one optical fibre cable runs from the LNB directly to theinterface ("virtual converter"). It may not be needed if optical splitters are being used as they may provide sufficientattenuation. Our technical department can provide advice on balancing the system's gain and attenuation levels.

Triax TVQ 04 virtual quatro converter.

Converts the optical signal from an optical LNB to 4 (quatro)electrical outputs (the same as a quatro LNB). Outputs are vertical high band,vertical low band, horizontal high band and horizontal low band.

If the cable run is over 70m an optical LNB may be needed.An optical fibre cable connects to the LNB and this can go direct to the electrical interface or it can be split usingoptical splitters. Either way it must connect to an optical to electrical interface called a "virtual converter". Thereare two types. This one has a quatro output (the same as a quatro LNB) and the other (above) has a quad outputand is called a Virtual Quad Converter and is the same as a quad LNB. This quatro interface ("Virtual Quatro Converter") feeds into a multiswitch and then asmany outputs as are needed can then be provided by the correct multiswitch.

Triax pre-made optical fibre cables.

Use between optical fibre LNBs, splitters if required and virtual converters.Optical LNBs are needed for long cable runs. If the cable run is over 70m an optical LNB may be needed.An optical fibre can be a kilometre long and still have zero loss. An optical fibre cable connects to the LNB and thiscan go direct to the electrical interface or it can be split using optical splitters. Either way it must connect to anoptical to electrical interface (called a "Virtual Quad Converter") and there are two types. One has a quad output(same as a quad LNB) and the other has a quatro output (same as a quatro LNB). The quad output can feed 4 singletuner satellite receivers or two twin tuner satellite receivers. The quatro interface ("Virtual Quatro Converter") feedsinto a multiswitch and then as many outputs as are needed can then be provided by the correct multiswitch.Multiswitches can have up to 48 outputs but more than one multiswitch can be used if more than 48 outputsare required. Optical fibre cable is difficult to terminate without the correct tool and so it is best to orderpre-made optical cables with the connectors already fitted. Make sure the pre-made cable is long enough for thejob! Too long is not a problem as there is zero loss. It is also possible to overload the electrical interface and so anoptical attenuator should be fitted. This is needed if only one optical fibre cable runs from the LNB directly to theinterface ("virtual converter"). It may not be needed if optical slitters are being used as they may provide sufficientattenuation. Our technical department can provide advice on balancing the system's gain and attenuation levels.

Triax TOL52 Optical LNB

Optical LNBs are needed for long cable runs. If the cable run is over 70m an optical LNB may be needed.A high output LNB like a titanium 0.1dB 2nd edition and very low loss cable is fine up to 70m and perhapseven a little further but certainly for cable runs of 100m + an optical equipment is needed.An optical fibre can be a kilometre long and still have zero loss. The optical fibre LNB works from 12 voltsand so a 220-240V to 24V power supply is included. This supply should be situated as close to the LNB aspossible. Clearly if it is not close the LNB, the 12 volts may be reduced by the time it reached theend of a long cable (due to the voltage drop in the cable). If the LNB does not receive a enough voltage itmay not work correctly. An optical fibre cable connects to the LNB and this can go direct to the electricalinterface or it can be split using optical splitters. Either way it must connect to an optical to electrical interface(called a "Virtual Quad Converter") and there are two types. One has a quad output (same as a quad LNB)and the other has a quatro output (same as a quatro LNB). The quad output can feed 4 single tuner satellitereceivers or two twin tuner satellite receivers. The quatro interface ("Virtual Quatro Converter") feeds intoa multiswitch and then as many outputs as are needed can then be provided by the correct multiswitch.Multiswitches can have up to 48 outputs but more than one multiswitch can be used if more than 48 outputsare required.

Triax optical splitters.

Use to split optical fibre cable.Our technical department can provide advice on balancing the system's gain and attenuation levels.





Triax optical attenuator.

Use between optical fibre LNBs and virtual converters.It is also possible to overload the virtual converter and so an optical attenuator should be fitted. This is usually neededif only one optical fibre cable runs from the LNB directly to the converter. It may not be needed if optical slitters arebeing used as they may provide sufficient attenuation.
