Quality and Warranty

1. Quality & Reliability

We’ve heard many stories of quality issues from new clients with third-party transceivers being supplied with inferior “low quality” components.

The optical transceiver market is being flooded with cheaper, low quality products from vendors. The main reason for this is the availability of lower quality lasers and receivers which are the key components in optical transceivers. Many of these “pioneering start-up” transceiver manufacturers design their own circuit boards and manufacture their own transceivers for resale, albeit at considerable risk of failure or outright incompatibility with their end-user’s products. Using substandard components and technology, these start-ups are able to “buy into” the market by pushing their products at near cost price. Most of the time, these companies survive only a couple of years and leave a trail of substandard products in the field and the stories of failing systems we hear so often.

Most of KINSOM new business comes from our reputation for quality and reliability. We are proud of our sterling reputation in the market and would never consider taking risks by using low quality components. We have extensive knowledge and years of industry experience to make sure we only deliver the highest quality products and service. All of our optical transceivers come with a lifetime warranty, and because we test every single product individually at our test labs, we can be certain that every product we sell meets our own exact standards.

2. Warranty Backed

KINSOM warranty covers all defects in materials and workmanship for all products sold and manufactured by KINSOM. Only original, unaltered, and unmodified materials and workmanship are covered by this policy. This warranty does not cover damage caused by improper deployment, misuse, accidents, neglect, or the natural breakdown of materials over time. Products should be returned to us for evaluation. Items with defects in materials and workmanship will be repaired or refunded.

In KINSOM, we offer a lifetime warranty and limited warranty for different products varying on the materials, workmanship, usage rate, and the availability of the spare parts for each product.

2.1 Lifetime Warranty

  • What is Lifetime Warranty?

    A Lifetime Warranty means that products enjoy a warranty within their own practical life. For example, the practical life of transceivers is about 5 years in normal applications, so the lifetime warranty on transceivers would be 5 years.

  • Lifetime Warranty varies by products:

2.2 Limited Warranty

  • What is Limited Warranty?

    A Limited Warranty means that products enjoy warranty periods that are less than their practical life as they are consumable products.
