Reliable Connections in Hostile Environments
By utilising advanced UK designed and manufactured Expanded Beam connectors, we are able to ensure the highest level of optical performance and availability/reliability for our fibre optic cable assemblies.
A key advantage of this 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 2000 times it’s 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.
A lens ensures there is no physical contact between the fibres or the mating lenses, so no fragile alignment sleeves and recesses for dirt to accumulate. In summary it provides maximum reliability with the minimum of user intervention.
A typical tactical fibre optic cable systems consist of the following components (click the below images to find out more):

1. The Connectors for Each End of the Assembly |
1, 2 & 4 way Fibre Plug |
The rugged connectors feature a hermaphroditic coupling, fully sealed shell and rubber covered grip ring and are maintenance free.
The hermaphroditic connector design allows simple and quick deployment. If you need a longer length assembly you can simply daisy chain several reels of cable assemblies together.
Options include 1 core, 2 core, 4 core and 6 core in OM1, OM2 and OS1 types of fibre cable.
Hybrid assemblies are also available for increased flexibility, for example:
2x Single-mode Fibre Optic Channels, 2x Size 16 MIL-C-39029 Power Contacts & 2x Size 20 MIL-C-39029 Signal Contacts, IP68 rated

2. The Mil-Tac Fibre Optic Cable |
Fibre Optic Cable |
The cable we use for these assemblies is designed for harsh environments where repeated deployment and retrieval for reuse is needed. It's extremely strong, with a high crush resistance whilst remaining lightweight and flexible.
Tested and in use for military tactical fibre optic cable field applications, they are also suitable for petrochemical, mining and broadcast requirements.

3. The Complete Assembly on a Deployable Reel |
Hand Carry Reel |
A variety of portable deployable reels are available to suit different lengths of fibre cable. These can be lightweight durable plastic or metal in construction, and have a hand carry handle or a frame and straps for back mounting.
|
|
4. Bulkhead + Tail Assemblies |
Bulkhead with LC Tails in Panel |
At each end of the fibre optic cable assembly you will need to convert the expanded beam connector to a more traditional butt-joint connector such as SC, LC, ST, FC etc. For this we offer a bulkhead assembly with ruggedised tails or pigtails.
These can be mounted into a 19" panel (shown) or a bespoke arrangement, or be free ends (unmounted).
