However well you plan your installation, fiber cable is rarely the right length for each run, and is inherently difficult to join. Consequently, cables have to be connected or cut in the field, with the potential issues this entails. This blog post looks at the various options available to installers for responding to these issues; from splicing and field-fit connectors to factory-terminated or pre-connectorization.
1. Splicing in the field
When fiber was first deployed, it was mechanically spliced, meaning that fibers were butted together as tightly as possible and then mechanically encapsulated. Due to the potential for signal loss and poor reliability this was soon superseded by fusion splicing. This offers the best quality connection of all in-field options in that the fiber ends are lined up and welded together. No excess cable is left over when the process is complete.
