It is extensively known that there are three famous brands of optical communication industry, Cisco, H3C and Huawei, whose products take the full advantage of popularity of brand. While the real needs of consumers are easier to be ignored, what do they most care about in fact? Is that Brand or Price? In my view, It is the comprehensive cost performance of products.

Nowadays, an increasing number of customers takes the compatibility into their consideration, as a result of the fact that the OEM fiber optic transceivers are extremely expensive at price and the second-hand ones usually can not be used over half a year even though the price is low. In spite of compatible products getting popular, there also exists differences in their performance and prices due to the different chips and techniques used by different manufacturers. So here we work out some useful tips to help you have a happy purchase.

How to choose a proper fiber optic transceiver?

1. The after-sales service

Generally, fiber optic transceivers can be used at least for 5 years. For most of them, people can not tell their real performance until the second or third year of use. Therefore, if you buy this product for the first time, you can choose providers with longer warranty. And if it’s not the first purchase, you should know the after-sales service is pretty important for a cost-effective purchase. Especially when there is trouble with the product, it is a good chance to identify if you had a right choice. So make the most use of your experiences on after-sales services, which will give you useful points.

2. Compatibility between fiber optic transceiver and device

Because of the diversity of device from different manufacturers, the compatibility between transceiver and device becomes one of the major issues for consumers. This issue can be easily solved through communicating with providers prior to purchase, and you are also suggested asking for a test of the true device before shipping, thus you will have a more accurate evaluation.

3. Compatibility

Types of fiber optic transceivers are getting richer, but the compatibility between different types always makes more or less effect on the network. It should be known that this product is standardized in terms of the related international criteria, so compatibility is not a problem as long as products meet with the criteria and are certificated by FCC.

4. Temperature adaptation

The generated temperature inside fiber optic transceivers is low, while they are more often used in the Switches and computer room, which causes the temperature get high or lower. When temperature gets too high or too low, it will affect the parameters such as optical power, optical sensitivity and so on.
