The fibre kit replaces the standard multiple coax cables from the below deck equipment (BDE) to the above deck equipment (ADE – the antenna), with a single fibre optic cable.
It is suitable for use with the Sea Tel 4012GX, XX12, XX09G2/XX10 and 97XX antenna systems.
“Running multiple coax cables over significant distances on large vessels can be very problematic in terms of the initial installation, maintenance and antenna performance, which may impact on quality and availability of the voice calling and data connectivity on board,” says Darren Manning, senior product manager, Cobham SATCOM.
Each kit contains a 1U rack mountable BDE interface, which receives the coax cables and is linked by fibre cable to an ADE interface that is typically installed in the radome base. Cobham says that no modifications or additions to the equipment frame are needed and that necessary interface cabling is included making the kits suitable for existing and new installations.
Status LEDs on the front panel of the BDE enclosure and on the top of the ADE interface box provide visual status of the fibre optic link, enabling engineers to check the connection between the BDE and ADE should an issue with the vessel’s communication service arise.
“Using a single fibre optic cable is a much smarter, more efficient solution than running multiple cables over very long distances, which can be a huge challenge when developing communication networks for large ships, offshore vessels and platforms,” says Mr Manning.
