A cold connection, also known as a fiber optic cold connector, is used when connecting a fiber optic docking fiber or a pigtail. This method is essentially creating a joint without the need for fusion splicing. The typical attenuation is 1dB per connection. The incoming optical fiber or indoor optical fiber can be inserted into the mechanical. Here we mainly introduce three commonly used fiber optic connection methods. In fact, standard interface connectors are simply not robust enough to. Fischer Connectors offers not only standardized products that operate within certain temperature ranges, e.
