Primarily fusion splicing is required on outside plant installations using single mode fiber as opposed to a Local Area Network installation using multimode fiber.
If, for example a single mode cable run is too long for a straight pull, or if we are working with multiple cable types, or if we are restoring a cable that has been accidentally cut through, we would need to connect fibers by splicing. There are two types of splices: fusion and mechanical. When splicing is required on a single mode installation, our technicians “weld” the two fibers together with the aid of a costly tool known as a fusion splicer.
The mechanical splice requires holding the ends of two fibers together with specific tube or clamping hardware and adhesive of specific formulation for the task, such as index matching gel or glue. In this case practice makes perfect regardless of the fiber mode; therefore it can be stated that the mechanical method would be deployed rarely due to the higher cost per splice.
Furthermore because of low back reflection, fusion splices are optimal for high speed networks on single mode fiber and in for either single or multi mode fiber when cabling splicing would be required underwater or overhead (aerial).
Optinet System’s technicians adhere to manufacturer instructions whether terminating multimode or single mode connectors. In the case of multimode there is more than one type of termination so knowing the difference and employing the most appropriate method is critical to minimizing dB loss. |
