all signals over just one fiber core
FieldCast Mux/Demux Three 3G
buy16 channels of 3G SDI video over one fiber optic channel
Mux Three Plus 3G and its twin brother Demux Three Plus 3G allow you to transport sixteen independent channels of 3G SDI video over just one fiber optic channel.
Is your infrastructure such that you have limited access to individual fiber optic connections? Mux Three and Demux Three can help you run multiple video channels without the need for separate cables.
Or else, do you want to roll out a minimum number of cables in live event environments,
just use Mux Three and Demux Three, multiplex up to sixteen channels of video,
and get all data from A to B using only one
strand of fiber!
No hidden processing involved! All 3G video
signals preserve full data integrity! What goes in
comes out, unchanged.
Features
Transport over long distance
The mux/demux pair can transport video over distances of up to 40 km/24 mi for 3G SDI. The mux is typically placed at the camera side, and the demux at the control room side.
16 independent video channels with loop-through and dual output
The set supports 16 independent SDI video channels. The SDI inputs have a reclocked loop-through. The SDI outputs are dual. Hence, monitoring on both sides (input and output) is possible. The SDI input is typically connected to the camera’s SDI output. The SDI output is generally connected to the SDI input of a monitor or switcher.
Transport over one fiber optic core
All information for up to 16 SDI video channels, back and forth, runs over a single fiber optic core. This means a simplex fiber optic cable is sufficient to bridge the distance between the mux and the demux, saving on fiber optic cable costs. Alternatively, if you have a fiber optic cable with 2 cores, you have 1 core (or channel) left for other fiber optic transport. You might, for example, use the free fiber optic core to connect to a second, similar Mux/Demux pair to add redundancy to your setup.
No compression
There is no signal processing involved, so there is no compression; full data integrity is guaranteed.
Unidirectional video by default
The standard model is unidirectional, meaning that 16 SDI signals go from mux to demux; it’s denoted as 16i/o, where ‘i’ stands for input and ‘o’ stands for output.
Bidirectional video on request
Upon request, the direction of the SDI signals can be changed to bidirectional. Customization is done at the factory level and built as requested.
Custom bidirectional models can be configured in any way, for instance, 8 channels mux to demux and 8 channels demux to mux (8i/8o), or 14 channels mux to demux and 2 channels demux to mux (14i/2o, which is technically the same as 2i/14o).
Logically, all possible custom solutions for a 16-channel multiplexer set can be configured as follows: 1i/15o, 2i/14o, 3i/13o, 4i/12o, 5i/11o, 6i/10o, 7i/9o, 8i/8o. The next logical successor, 9i/7o, is the same as 7i/9o and was already listed before.
LC fiber by default
By default, the mux/demux set is supplied with an LC single mode fiber optic port. On request, other fiber ports, such as SC or ST connectors, can be built in.
