Blue Box 4 channel link 3G-SDI/HD-SDI/SD-SDI/ASIpdf

The Bluebell Blue Box QUAD 3G is a 4 channel multiplexer/demultiplexer that makes 3G-SDI to fibre conversion over hybrid or military tactical cable possible. The Blue Box QUAD 3G provides a compact conversion unit which allows the outputs from up to four cameras to be transmitted over a single standard hybrid or military tactical cable.

Each signal within a fibre core has a different optical wavelength, enabling interference free transmission over longer distances. The system is available in different configurations all operating over a single cable link.

● Four signals can be sent from the remote or camera end to the OB Truck
● Two signals can be sent in either direction
● Three signals in one direction with a reverse feed

Power is provided via the PS10/XLR unit supplied with the system. The PS10/XLR has an IEC mains inlet allowing easy adoption into standard equipment bays. The QUAD 3G has a 4 pin XLR allowing power from a variety of external DC sources in the range 4.5 to 17 V.

Applications have been found in many Outside Broadcast vehicles, special event companies and in pre-fibred venues, particularly with the advent of 3D and the move to a 3G infrastructure.
Units can also be used in conjunction with any standard Bluebell frame or enclosure.
Each Blue Box enclosure is a robust aluminium enclosure suited to the demands of constant rigging/derigging.

blueboxEach Hybrid or Tactical Fibre cable contains two singlemode fibres.
The Blue Box multiplexes two separate wavelengths or services onto each fibre.
Each wavelength is independent.

In the case above four signals are being transmitted in one direction.
