Fusion Splicing Versus Mechanical Splicing

Fusion Splicing Versus Mechanical Splicing – Which is Better?

Fibre optic cables are the best choice for the fastest data transmission technology. The installation process of the optic fibres requires skilled hands. The most crucial part is to skillfully fuse the two stubs or ends of the fibres. Any kind of failure or fault makes the entire network weak. The chaotic network signal is the end result.

Cable splicing is the procedure that helps to join or fuse two or more ends of the optical fibres. Cable fusion procedure requires optimum care for super-fast network performance.

Fibre optic cables do not come in the required length of the network. This calls for fusing two ends of fibres to make a long fibre cable matching the requirement. There are two popular methods for termination of the fibre optic cables:

  • Mechanical Splicing – cables are joined with the help of fibres
  • Fusion Splicing – cables are joined by welding over an electric furnace

Both the processes score on advantages but do have their share of disadvantages. Here’s an attempt to study the same and find out which method of cable splicing cable network installers’ first choice.

Fusion Splicing & Mechanical Splicing

Fusion Splicing seems to be a better option than mechanical splicing. The following points will justify the same:

  • Level of precision during installation – Fusion splicer is used to fuse or weld to perfectly aligned optical cable fibres unlike the connectors used in mechanical splicing which just holds the two fibres.
  • Mass Fusion Operation– 12 optical cable fibres can be fused together in a single operation by the fusion splicing method. Single fusion can also be done in fusion splicing.
  • Permanent Solution – Fusion splicing permanently welds two fibres as compared to a mechanical method which is meant for temporary holding of fibres.
  • Reliable Network Connectivity – In the fusion splicing method there is no chance of moisture or dirt leakage. This ensures the smooth transmission of light signals through the fibres of the cable network. In the case of mechanical splicing, connectors may suffer damages. Faults developed in due course of time are sure to diminish the quality of network signals.
  • Lower Variable Cost – Investment in fusion splicer equipment makes fusion splicing method a pricey option. But this method has a lower variable cost. The charge perfusion splice is $ 0.50 to $ 1.50 as compared to mechanical splicing whose variable cost is in the range of $ 10 to $ 30 per slice.
  • High-level Performance – The insertion loss for fusion splicing is lower than the mechanical splicing method. In the mechanical procedures, fibres are not joined permanently (they are just aligned). This results in a loss of signal power. Infusion splicing the connection of the fibres of the cable is continuous. Thereby, network failure and weak signals are almost ruled out.

Concluding Lines

Fusion Splicing is a popular choice. But when the temporary restoration is required it is better to opt for mechanical splicing. The mechanical method definitely seems cost-effective in respect of upfront value (no expensive equipment is required).

Mechanical splicing is not a suitable choice when installers need to splice cables on a large scale. A large number of splices mean a higher variable cost.  Fusion splicers are nowadays available at a reduced price or on a rental basis. These account for making fusion splicing method a budget-friendly choice for fibre cable network installers. Until the time newer data cable installation technologies, evolve fusion splicing is sure to enjoy the limelight.

Cable fusion specialist engineers have the best knowledge and skills in cable installation. Seek professional help when you need to deploy a new network or wish to expand an existing network.
