Why ArmourLux with F BEAM®?

The most Reliable Fibre Connection

The F BEAM® connector is an Expanded Beam connector that utilises Advanced Alignment Technology. Expanded Beam lessens the contamination risk associated with physical contact connectors so is suited to the most rugged and demanding of applications.

A key advantage of this fibre connector design is that the fibres are protected from the elements and each other. Rather than the traditional butt joint which requires each fibre core to be precisely aligned (to within a micron), expanded beam employs a precision lens to optically expand the light from each core by approximately 40 times its original size, and then refocus back into the mating connector.

A small gap is maintained between the lenses, this minimises the effect of dust, debris, temperature variation, vibration and dirt on the lights path. The lens also means it can be easily cleaned without risk of damaging the fibre – if a connector is dropped into mud, it can simply be washed or wiped and reconnected.

As the lens magnifies the light from the fibre cable (potentially from just 9 microns) accurate alignment of the lens and the fibre is critical to a high-performance connection. Much of the development of the F BEAM has been in this area, enabling insertion losses to be class-leading.

IP68 rated for peace of mind

The F BEAM connector has been tested to an immersion depth of 15m operational (EN 61300-2-45) and is IP68 standard.  You can read more about IP ratings here.

Greater reliability in harsh environments

The ArmourLux range uses a tough, durable Miltac cable that tightly packs bend insensitive fibres in aramid yarn, ensuring minimal signal loss even if accidentally kinked.
