Flight simulation

Existing fibres within the cockpit of a flight simulator were being broken due to “jack-knifing” during the removal and replacement of the individual Cockpit Modules (CPM’s).

Military aviation

We designed and manufactured each of the inspection and cleaning guides for all the known fibre optic connectors, both male and female within the Typhoon Fighter Jet.

Mission-critical repair

Working with a leading aerospace client, we provided a solution to replace existing fibres which were being jack-knifed within their flight simulator cockpits.

Serving the Military with mission critical requirements

Alker Fibre Optics is an approved supplier direct to the UK MOD and a trusted partner for a number of specialist prime contractors within the military sector.

Our team are highly skilled fibre optic designers and manufacturers, with expertise in producing reliable high-performing rugged solutions that are of a mission-critical nature.

From emergency repairs and upgrades to bespoke solutions and products, we will improve performance and reliability, extending the in-service life of your assets containing fibre optics in harsh and extreme environments.

Specialist consultancy, tailored solutions

The applications that require stable, dependable high-performing mission-critical fibre optics are ever-increasing and show no sign of slowing in all industries, including academia, research and development.

With over 40 years’ experience, our team of engineers have a legacy of developing bespoke fibre optic solutions for a wide range of market sectors. We hold several protected patents, a testament to our fibre optic expertise and reputation as industry leaders. Once we commit to a client, we’ve yet to encounter a fibre optic problem we couldn’t solve.

Precision manufacturing for critical applications

At Alker, we are proud to produce our tailor-made range of fibre optic solutions at our manufacturing facility in Surrey. Our UK facility means we can fast-track mission-critical components for high-pressure projects including ones destined to the military, this also avoids the complications that ITAR is associated with.

Alker fibre optic splice pipe enclosure

Our fibre optic splice enclosure is a device specially designed to provide maximum protection for vulnerable fibres when splicing is required.

We have designed an innovative range of inline enclosures that are superior to any competing products currently available in the market. The enclosures have numerous advanced features that greatly emphasise the practical benefits.

Sacrificial Fibre Optic Adaptors

Tailored to each specific set of fibre optic connectors or bulkheads, sacrificial adaptors are an excellent solution to eliminate damage to fibre optic harnesses or bulkheads, which are often attached to mission critical assets.

Responsive repair and trusted support

In response to growing customer demand, we provide comprehensive emergency fault finding and repair support for damaged and faulty fibre optic connections.

The skilled team at our UK manufacturing facility will assess faults onsite to quickly determine the root cause of any issue, carry out repairs, and get you up and running to minimise downtime and disruption.

It’s our commitment to provide a quality service, to minimise future recurring problems and to extend the in-service life of your products.
