Splicing •A way of connecting two
individual optical fibers
together.
•Basically, splicing is used for;-
-to repair a damaged cable.
-to establish long-haul
optical fiber links.
-to join two different cable
types. FITL Fusion Splicer

What is a Loss Budget
calculated by adding the average losses of all the components used
in the cable plant to get the total estimated end-to-end loss.
That’s Include all Connections between Tx and Rx, Such like:-
Number of Connectors, Couplers.
Number of Splices.
Length of Fiber optic cable.
Tx Output Power – Rx Power = Loss Budget
