There are many products in the field of optical communications that vary in quality. Take the jumper as an example, the first thing to ensure is its plug back loss and quality weight, because the jumper is mainly used in the central room to connect OLTs or other devices, if the jumper parameters do not meet the standards, it will increase the optical power loss, resulting in the impact on the entire network. Here are our tips for purchasing a dual band combiner manufacturer:

1. High precision plug is used to reduce plug loss. For example, the standard of plug loss in the market is ≤0.3dB, and the jumper produced by Kehai can fully meet this standard, or even ≤0.2dB if customized by customers. Some products on the market often use recycled plug, connector, optical fiber and so on to reduce costs, but will bring great plug loss.

2. Core-to-core degree is also a very important parameter index.0 is a value of ideal state, and the core-to-core degree of our jumper is 1.0um. Kehai can also customize some jumpers with the same core degree of 0.5um or even 0.3um for customers. Because the same core degree is small, the data transmission will be better.

3. The good of the spare parts is not only because of the high loss, but also because it is difficult to plug and pull. The spare parts of the jumper produced by Kehai are all independently produced, reaching the international standard. The requirements are met.

4. In addition, the composition of the spare parts, the grinding of the connector, etc., will affect the quality and weight of the jumper. Kehai has a set of jumper production line to ensure the quality and weight of the jumper. Before the jumper leaves the factory, we will have a series of testing equipment such as 3D measuring and adjusting, inserting loss instrument, optical fiber magnifying glass and so on to test the quality of the jumper.
