We specialise in the termination of optical fibres, connectors and devices across diverse sectors, medical, aerospace, sensor, telecommunications, defence and more.
Alker is pioneer in the field of innovation, design and manufacture of fibre optic assemblies for harsh environments. There are many applications requiring fibre optics to work in extreme temperatures, wet or dry environments, or enduring excessive vibration. We are continually expanding the array of connectors we can successfully armour to withstand the demands expected in extreme conditions.
Stainless steel armouring
Alker can provide stainless steel armouring in a range of diameters. For applications which have weight limitations or are within a confined space, our Micro Armouring™ range is the ideal solution. Starting with 1.5mm through to 3mm diameters, this specially designed armouring offers the high level of protection required. For larger applications, we can provide 4.5mm through to 25mm diameter for either single or multi fibre assemblies. This range is the perfect choice for fibre optic looms or harnesses, which can include both fibre and electrical contacts.
Splitters and Dividers
Alker has developed a series of multiway breakout splitters and dividers which enables us to manufacture complex breakout assemblies. We also have the facility to design and manufacture custom splitters and dividers.
Polarisation Maintenance (PM) Armoured Optics
The Alker Polarisation Maintenance (PM) Armoured Optic process can be used on a range of connectors. With high extinction ratios, our rigorous orientation specification and added protection because of the armouring, all allow Polarisation Maintenance (PM) fibres to perform in environments not previously possible. The orientation of the fibre is available in fast, slow or custom axis in either FLAT, UPC, 8° FLAT or APC polished finish. The range of connectors includes FC, SC, LC, MU and E2000. A bespoke design and manufacturing facility for custom requirements is available.
Armoured leads for high temperatures (HT)™
Armoured HT Optics™ is a range of assemblies using connectors specifically designed for the power turbine and the jet engine sensor industries. The insulation process protects the entire length of the assembly and allows their use within higher temperatures.
Micro armoured 90° curved connector boot
This innovative compact connector has been designed and constructed by Alker technicians. A customer-driven concept that became one of our standard products. It has a unique curving system (with a choice of angle from 0° to 90°) and is an ideal solution where space is limited. The distinctive curve will also prevent the cable from being trapped or damaged. Insertion loss is less than 0.2dB. It is currently available for the LC, FC, SC, MU, ST and SMA connectors and most fibres.
