To ensure the highest quality products, Westermo has a state of the art industrial electronics manufacturing facility in Sweden. To maximize the reliability of the product, testing is carried out at many stages of the manufacturing process. To demonstrate this confidence in our products, all Westermo products are warranted against defects in design, materials or workmanship for a time period of five years. The warranty also covers fibre transceivers, which is seen as an accessory by many other vendors and therefore not covered.
