Verify Splicing and Heating Settings: If the splicer is set to Auto, change the programs to align with the fiber type you are using. Confirm the Cleave Angle is Accurate: Proper cleave angles ensure better fiber splicing, leading to lower loss levels. That is usually done for permanent connections, but it may be possible to dismantle a splice without spoiling the fiber ends. This leads to particularly low insertion loss and high return loss. Fiber optic splicing combines precision mechanics, material behaviour, and environmental factors, all of which influence the result. These precision tools align and fuse optical fibres together using an electric arc to form a single long fibre. Two different methods exist for splicing fibers: Typical splice loss values (the measure of loss in optical power across the splice point) are usually lower for fusion splices (typically less than 0.
