OPTICAL Systems Design has announced the availability of its OSD290 FM-FDM multiplexer for real time transmission of four video signals over multimode or singlemode optical fibre cables.
The system can be supplied with a variety of optical devices which allow it to operate over 3 to 5km of multimode fibre and up to 150km of singlemode fibre.
The unit is a simplified and downsized version of the OSD390 video/audio/data multiplexer and is available as a small standalone module or a card which plugs into the OSD370 chassis.
A feature of the product is that, in terms of hardware, it is cost comparable with four individual single channel links.
The OSD290 is an economic choice when three or four signals need to be transmitted more than 500 metres.
