Blue Box SMPTE Hybrid Cable 4 channel link Dual Link/HD-SDI/SD-SDI/ASIpdf

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

Each signal within a Hybrid fibre has a different optical wavelength, enabling interference free transmission over longer distances. The system is available in different configurations all operating over a single SMPTE Hybrid 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 are sent in one direction with a reverse path monitor feed for example.

Applications have been found in many Outside Broadcast vehicles, special event companies and in pre-fibred venues.
Units can also be used in conjunction with a standard Bluebell BC100 frame.

Each Blue Box enclosure is a robust aluminium enclosure suited to the demands of constant rigging/derigging.

blueboxEach Hybrid 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 three signals are being transmitted in one direction with another signal being transmitted in the reverse direction. See the Ordering Information below for the different options.
