Fibre optic patch cords
We specialise in the termination of optical fibres, connectors and devices across diverse sectors, medical, aerospace, sensor, telecommunications, defence and more.
Alker fibre optic patch cord
The term fibre optic ‘patchcord’ is also referred to as a Jumper, Jumper cable, Lead, Assembly, Cable, Patch cable and more. They traditionally refer to a length of fibre optic cable which has been terminated at both ends with fibre optic connectors. Their aim is to lose as little light as possible, measured as a decibel (dB) loss or attenuation.
At Alker we have operated in the fibre optic field for over 35 years so if you have any requirement outside of our advertised ranges please contact us on 01342 870 941 and we will be happy to talk through your requirements.
Patchcords & Pigtails
At alker we offer a range of standard patchcords and pigtails. These utilise common fibre optic connectors and optical fibre including 9/125 OS1 (OS2) Singlemode, 50/125 OM2,3 and 4 Multimode and 62.5/125 OM1 Multimode and are available in 1,2,3,5 and 10m configurations to suit most installation needs. If you require a bespoke patchcord or pigtail use our ‘build your own’ service.
In 5 easy steps, we will guide you through the available choices of 13 fibre optic connectors, 3 optical fibres modes and 5 ruggedisations. Ordering hybrid patchcords or custom fibre optic assemblies online has never been so easy and at no additional premium over our standard patchcord configurations.
PM Patchcords & Pigtails
Polarisation maintaining patchcords and pigtails are manufactured by terminating tight tolerance keyway fibre optic connectors onto Bow-tie, Panda and Elliptical PM fibre. This results in a Patchcord with excellent extinction ratio and insertion loss results.
High extinction ratios, typically above 20dB
Low insertion losses, typically <0.2dB
We supply Polarisation Maintaining Fibre and can offer termination to the largest range of connectors available to any specification, everything bespoke to your requirements right here in the UK. Full armouring service also available for use in harsh environments.
Our products are globally competitive and are designed for repair to extend the in-service life of our products.
Fibres available from:
Attenuated patchcords reduce the light transmitting through the fibre, reducing the insertion loss from anything between 1dB to 20dB. Higher dB values can be manufactured if required. Fixed attenuator – off-set splice.
Variable optical attenuator (VOA) can be adjusted from 1dB to 20dB.
Either fixed or variable attenuators can be terminated with most fibre optic connectors within our UK Termination House.
Angled Connector Patchcords
We have developed a standard connector range to exit the connector and go round a 90-degree bend, therefore shortening the overall length of the connector. This 90-degree bend can be orientated north/south/east/west as required.
We ensure quality, reliability, and safety for complex and sensitive fibre optic assemblies in spacecraft engineering and research.
Armoured assemblies, inspection and cleaning solutions are proven to add value to your military assets.

Richard Alan Kershaw
Our brief to Alker was to design & manufacture fibre optic assemblies in preparation for our ultrasonic sensor technology to be used in harsh and extreme environments. Despite the challenge and changing requirements, Alker was always very accommodating with the aim of providing consistently high-quality service in a short time frame.read more
