Fitel technical support network in Europe, the Middle East and Africa

At Furukawa, we pride ourselves on providing our customers with excellent technical support, not only directly but also through a network of distributors who are experts on Fitel fusion splicers. Many of our distributors in Europe and the Middle East have their own repair centres, which provide technical support and carry out repair and servicing on our machines. All authorised repair engineers are fully trained on maintenance of our splicers and cleavers in our training centre in the UK.

Should you require advice on how to use your Fitel splicer, or if your machine does not give you entire satisfaction, please contact your local Fitel distributor. Please refer to the "Service Centres" section to find your nearest distributor.
