Link Microtek previews Azdec optical comms system at DSEI 2019

At this year’s DSEI exhibition (Excel, London, UK, 10-13 September 2019), Link Microtek will highlight the Azdec optical mobile local communications (MLC) system. This allows secure cable-free voice communications for a range of military applications

The secure, non-RF, cable-free voice comms system was originally developed using infra-red technology to provide secure bridge communications on board naval vessels. The Azdec system has now been adopted in other military scenarios where RF transmissions might jeopardise security.

From submarines to unmanned aerial vehicle (UAV) control rooms and from satellite payload test facilities to forward command centres, operators can use the Azdec system to communicate securely while roaming from their base positions, without trailing wires.

Micro-LED arrays provide optical transmissions at a wavelength determined by the requirements of the specific application, explains Link Microtek. According to the company, the Azdec system delivers crystal-clear, short-range voice communications. It also carries a Class 1 product designation as defined by the EN 60825-1 standard, which means it presents no ocular or other health hazard to users.

The optical digital encoding technology used is immune to radio, radar and electrical noise – even severe energy pulses – and has no effect on sensitive electronic equipment, flammable atmospheres or munitions. There are no RF emissions and the signals cannot be intercepted by any conventional method, so the transmissions cannot be jammed or subject to eavesdropping, claims Link Microtek.

Capable of providing secure multi-channel communications for areas of up to 4,000 square metres, an Azdec system typically comprises a compact basestation, a number of fixed antennae, headsets, operators’ belt-mounted battery-pack or control units and a central battery charger unit.

Link Microtek’s stand will also highlight other Azdec developments of a
through-water system allowing short-range underwater optical communications, a long-range system for use on ships’ heli-decks, and a secure cable-free data link capable of transmitting command signals, video, sound and other data to, say, unmanned ground vehicles involved in explosive ordnance disposal.

Link Microtek will exhibit at DSEI 2019, stand S3-435.
