Here we have for sale our 1500mm long M.O.S.T fibre optic POF Polymer (or Plastic) Optical Fibre extension cable with brass ferrule ends suitable for use in automotive MOST fibre optic rings to control audio/visual equipment. We can also supply the following cable lengths: 250mm, 500mm, 750mm, 1000mm, 2000mm and 4000mm, please see our other listings for other cable lengths. Our high quality cables are manufactured to exacting standards under strict Quality Assurance procedures. Please be aware that some fibre optic cables originating from the Far East are inferior in quality and the ferrule ends may not be fusion welded. This can result in data being 'dropped' on the fibre optic ring causing spurious faults. 

We have sold over 2000 of our fibre optic products to DIY enthusiasts, garage workshops, specialist audio installers, the automotive trade and even BMW & Mercedes Main Dealers; many of these are repeat customers. We have exported our products to over 40 countries across the world and pride ourselves on the speed of our despatch (normally the same day as payment is made if during office hours Mon to Fri). Our UK customers normally receive their order within 2 working days of payment. We provide full after-sales technical support for our products and are proud of our 100% positive eBay feedback.

European vehicle manufacturers including Mercedes, BMW, Porsche, Audi, Jaguar, Land Rover and Volkswagen interconnect the audio/visual equipment within their vehicles using a M.O.S.T (Media Orientated Systems Transport) fibre optic ring. We have been advised that other vehicle manufacturers also use the M.O.S.T ring with Tyco (TE) connectors including Aston Martin, Honda, Toyota, Volvo, Saab, General Motors, Hyundai and Kia. We can see no reason why this extension cable should not also be fully compatible with these vehicles.


The common modules connected on a vehicle M.O.S.T ring are: CD Changer, Video Display, GPS Navigation, Mobile Phone, Voice Recognition, Amplifier and Digital/FM/AM Tuner.

If you wish to repair, adapt or extend an automotive fibre optic ring (i.e. to add an additional module to the ring) you will require additional fibre optic cable with ferrule end connectors to repair, extend or modify the existing M.O.S.T ring while maintaining the integrity of the ring. We can also supply at extra cost Tyco (TE) male connectors, Tyco (TE) female connectors and Tyco (TE) in-line connectors to extend the ring or bypass a faulty section of the M.O.S.T ring. Please ask for further details.

Vehicle M.O.S.T rings include a male Tyco connector at each module location which plugs into the back of the modules.  This male connector has a fibre optic "in" and "out" cable forming a fibre optic ring connecting all the modules together with the head unit.

A typical application for the use of this cable is to extend the existing fibre optic ring to add a new module to the ring i.e. a CD changer or to bypass a faulty section of the ring. The existing fibre optic ring cable and the new extension cable can be joined by a Tyco in-line connector (which we can supply at extra cost). This connector will correctly align the two ends of the fibre optic cables to ensure no data loss or corruption at the joint. Please note that your vehicle may need to be 'programmed' to recognise the new module fitted.

For further background information we have included links to the manufacturer's drawings for the male Tyco connector, Tyco cable terminator and female Tyco connector so that you can ensure compatibility with the type of MOST fibre optic ring and connectors fitted in your vehicle.

Mercedes Owners Only

Early Mercedes vehicles fitted with a fibre optic ring employed the D2B system which used a different type of cable ferrule end connector. Between 2004 and late 2006 Mercedes transferred to the standard M.O.S.T fibre optic ring system. So if your Mercedes is a pre-2007 model, please check if your Mercedes is fitted with D2B or MOST connectors prior to ordering.
